An air-conditioning unit comprises a compressor component for compressing a refrigerant, a condenser component for condensing the refrigerant, and an evaporator component for evaporating the refrigerant. At least two of the compressor, the condenser and the evaporator components is assembled integrally. This prevents with certainty leakage of the refrigerant that circulates through the air-conditioning unit.
Description
- The present invention relates to an air-conditioning unit.
- Recently, various low-pollution vehicles have been developed as a response to environmental problems. Electric vehicles, one type of low-pollution vehicles, have been developed actively and put to practical use. Each electric vehicle runs a drive motor using a battery as the energy source. A motor-driven compressor, which uses an electric motor as the drive source, is used as a compressor for an air-conditioning systems in electric vehicles.
- For example, Japanese Unexamined Patent Publication (KOKAI) No. Hei 8-216671 discloses an air-conditioning system that uses a motor-driven compressor as shown in FIG. 7.
- A
case 52 of an air-conditioning system 51 houses acondenser 53, anevaporator 54 and a motor-drivencompressor 55. Thecase 52 is divided into first, second andthird chambers first chamber 60 accommodates thecondenser 53, thesecond chamber 70 accommodates theevaporator 54, and thethird chamber 80 accommodates a horizontal type motor-drivencompressor 55 and a four-way valve 56. Thecondenser 53, theevaporator 54, the motor-drivencompressor 55 and the four-way valve 56 are connected together bypipes 57 a to 57 d, which form a passage for a refrigerant gas. A motor-driven expansion valve 58 is provided on thepipe 57 c that connects thecondenser 53 to theevaporator 54. - In consideration of environmental problems, carbon dioxide has recently been used as a refrigerant. In this case, the pressure inside each of the pipes57 a-57 d is higher than that where chlorofluorocarbon, or freon, is used as a refrigerant. This causes refrigerant gas to leak through the joint sections of the pipes 57 a-57 d. When the pipes are long, the probability of cracks and other kinds of damage increases. Such damages including cracks will result in leakage of the refrigerant gas.
- Accordingly, it is an object of the present invention to provide a compact air-conditioning unit that prevents with certainty leakage of the refrigerant that circulates through the air-conditioning unit.
- To achieve the above objective, the present invention provides an air-conditioning unit. The air-conditioning unit comprises a compressor component for compressing a refrigerant, a condenser component for condensing the refrigerant, and an evaporator component for evaporating the refrigerant. At least two of the compressor, the condenser and the evaporator components are assembled integrally.
- Other aspects and advantages of the invention will become apparent from the following description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.

- A first embodiment of an air-
conditioning unit 1 of a vehicle air-conditioning system will be described with reference to FIGS. 1 and 2. - As shown in FIG. 1, the air-
conditioning unit 1 is installed in, for example, the engine compartment of an automobile. The air-conditioning unit 1 has a motor-drivencompressor 2 which compresses refrigerant, acondenser 3, which condenses the refrigerant, and anevaporator 4, which evaporates the refrigerant. The motor-drivencompressor 2 has acompressing mechanism 5, amotor 6 and a drive circuit 7. The drive circuit 7 controls the rotational speed of themotor 6. The discharge capacity of thecompressing mechanism 5 is changed in accordance with the rotational speed of themotor 6. The discharged refrigerant flows from the motor-drivencompressor 2 to thecondenser 3 and from thecondenser 3 to theevaporator 4. Then the refrigerant returns to the motor-drivencompressor 2. - Four brackets8 (three shown in FIG. 1) are integrally formed on a
housing 2 a of the motor-drivencompressor 2. The motor-drivencompressor 2 is attached to thecondenser 3 by thebrackets 8 by unillustrated bolts. Afirst connector 9, where afirst pipe 17 a, including a pipe and hose, is attached, is provided on one end surface of thecompressing mechanism 5. Formed in thefirst connector 9 is aninlet port 10, which communicates with a suction chamber (not shown) in thecompressing mechanism 5. - The
condenser 3 is provided with a gas-liquid separator 11. Thecondenser 3 is also provided with asecond connector 12, where asecond pipe 17 b is attached. Formed in thesecond connector 12 is adischarge port 13, from which refrigerant that has been separated by the gas-liquid separator 11 after condensation in thecondenser 3 is discharged. - The
evaporator 4 is provided with athird connector 14, where end portions of thepipes third connector 14 are aninlet port 15, from which the refrigerant enters, and aexhaust port 16, from which the refrigerant gas evaporated by theevaporator 4 is exhausted. Thedischarge port 13 of thecondenser 3 and theinlet port 15 of theevaporator 4 are connected together by thesecond pipe 17 b. Theexhaust port 16 of theevaporator 4 and theinlet port 10 of the motor-drivencompressor 2 are connected together by thefirst pipe 17 a. Anexpansion valve 18 is provided on thesecond pipe 17 b. Ablower fan 19 is located near theevaporator 4. Theblower fan 19 and theevaporator 4 are located in aduct 20. - A
discharge pipe section 21 is integrally formed on one end surface of thecompressing mechanism 5. Thedischarge pipe section 21 communicates with a discharge chamber (not shown) in thecompressing mechanism 5. Thecondenser 3 has aninlet pipe section 22 integrally formed at a position corresponding to thedischarge pipe section 21. The discharge andinlet pipe sections nipple 23. The discharge andinlet sections nipple 23 form apassage 24. The motor-drivencompressor 2 is connected to thecondenser 3 via thepassage 24. - FIG. 2 shows the cross section of the
passage 24 that connects the motor-drivencompressor 2 to thecondenser 3. Formed on the inner surfaces of the distal end portions of thepipe sections nipple 23 areexternal threads external threads nipple 23 are threaded into their respective internal screws 21 a and 22 a, the twopipe sections nipple 23. A discharge port 25 of thepipe section 21 is connected to aninlet port 27 of thepipe section 22 via acommunication hole 26 formed in thenipple 23. - Since the
pipe sections nipple 23, this embodiment does not use a pipe or a hose. Therefore, the joint in thepassage 24 where high pressure refrigerant gas, discharged from the motor-drivencompressor 2 enters thecondenser 3 is essentially nothing more than thenipple 23. - This embodiment has the following advantages.
- Because the motor-driven
compressor 2 is integrally attached to thecondenser 3, the distance between theinlet port 10 of the motor-drivencompressor 2 and thedischarge port 13 of thecondenser 3 is short. It is therefore possible to employ a structure in which bothpipe sections compressor 2 and thecondenser 3 so that thepipe sections - Since both
pipe sections - The unified motor-driven
compressor 2 andcondenser 3 can be treated as a single component. This makes it easier to install the air-conditioning unit 1 in a vehicle and reduces the installation space required for the air-conditioning unit 1. - The
passage 24 where the refrigerant gas under high pressure, discharged from the motor-drivencompressor 2, travels is not joined to a pipe. It is therefore possible to prevent refrigerant leakage where refrigerant leakage is most likely to occur. When the present invention is used in the air-conditioning unit 1, which uses carbon dioxide as the refrigerant, particularly, refrigerant leakage can be reliably prevented. - The air-
conditioning unit 1 according to a second embodiment of the present invention will be discussed below with reference to FIGS. 3 to 4B. This embodiment differs from the embodiment illustrated in FIGS. 1 and 2 in that the motor-drivencompressor 2 is attached to thecondenser 3 and theevaporator 4 to provide an integral air-conditioning unit 1 and is the same as the latter embodiment in other respects. To avoid a redundancy, like or same reference symbols are given to those components that are like or the same as corresponding components of the first embodiment. - As shown in FIG. 3, the motor-driven
compressor 2 is attached integrally to thecondenser 3 via thebrackets 8 by unillustrated bolts. The motor-drivencompressor 2 is connected to thecondenser 3 by thepassage 24, which is formed by directly coupling thepipe sections nipple 23. Thehousing 2 a of the motor-drivencompressor 2 has four second brackets 31 (only two are shown in FIG. 3) formed at positions corresponding to thefirst brackets 8. The motor-drivencompressor 2 is attached to theevaporator 4 by the foursecond brackets 31 by unillustrated bolts. The motor-drivencompressor 2, thecondenser 3 and theevaporator 4 are therefore unified. - The structure that connects the
exhaust port 16 of theevaporator 4 to theinlet port 10 of the motor-drivencompressor 2 is essentially identical to the structure that connects thedischarge port 13 of thecondenser 3 to theinlet port 10 of the motor-drivencompressor 2 in the embodiment illustrated in FIGS. 1 and 2. Specifically, as shown in FIG. 4(a), adownstream pipe section 32 is integrally formed on one end surface of thecompressing mechanism 5 of the motor-drivencompressor 2. Anupstream pipe section 33 is integrally formed on one side of theevaporator 4 at the position that corresponds to thedownstream pipe section 32. When thenipple 23 is fastened between the twopipe sections inlet port 10 and theexhaust port 16 are connected without using a pipe or hose. - The structure that connects the
discharge port 13 of thecondenser 3 to theinlet port 15 of theevaporator 4 is likewise essentially the same as the structure that uses thenipple 23. Specifically, as shown in FIG. 4(b), anupstream pipe section 34 is formed on one side of thecondenser 3. Adownstream pipe section 35 is formed on one side of theevaporator 4 at a position that corresponds to theupstream pipe section 34. When thenipple 23 is fastened between the twopipe sections discharge port 13 and theinlet port 15 are connected without using a pipe or a hose. Theexpansion valve 18 is located in thefourth pipe section 35. - According to this embodiment, like the embodiment shown in FIGS. 1 and 2, the motor-driven
compressor 2 and thecondenser 3 are connected together without a pipe and refrigerant leakage is prevented. Further, the assembly of the air-conditioning unit 1 is simple and the installation space required for theunit 1 is small. - The unitary assembly of the motor-driven
compressor 2, thecondenser 3 and theevaporator 4 shorten the distances between all the joint sections. This makes it possible to connect all the motor-drivencompressor 2, thecondenser 3 and theevaporator 4 without pipes or hoses. This considerably reduces the likelihood of damage, including cracks in the pipes. Since there are only three joints in the air-conditioning unit 1, refrigerant leakage are further prevented. Furthermore, the air-conditioning unit 1 of this embodiment is more compact than that of the embodiment shown in FIGS. 1 and 2, thus requiring a smaller installation space. - The embodiment may be modified as follows.
- For example, the motor-driven
compressor 2 and thecondenser 3 may be connected by apipe 41 as in the third embodiment shown in FIG. 5. In this case, the discharge port 25 of afirst connector 42 formed on the motor-drivencompressor 2 is connected to theinlet port 27 of asecond connector 43 formed on thecondenser 3 by thepipe 41. The unitary assembly of the motor-drivencompressor 2 and thecondenser 3 reduces the length of thepipe 41. This reduces the likelihood of damage, including cracks in thepipe 41, thus preventing of refrigerant leakage more reliably. - Further, the motor-driven
compressor 2 and theevaporator 4 may be assembled integrally, and the inlet port of the motor-drivencompressor 2 may be connected to the exhaust port of theevaporator 4 without using a pipe as in a fourth embodiment shown in FIG. 6. In this embodiment, the discharge chamber is provided in the inner portion of thecompressing mechanism 5, and the suction chamber is in the outer portion of thecompressing mechanism 5. Apipe section 44 extending from one side of theevaporator 4 and apipe section 45 extending from one end surface of the motor-drivencompressor 2 are connected together by thenipple 23. Thepipe sections nipple 23 form a passage 47. The discharge port 25 of the motor-drivencompressor 2 and theinlet port 27 of thecondenser 3 are connected by apipe 46 a, and thedischarge port 13 of thecondenser 3 and theinlet port 15 of theevaporator 4 are connected by apipe 46 b. This removes the pipe between the motor-drivencompressor 2 and theevaporator 4, thus improving the prevention of refrigerant leakage from the refrigerant passage between the motor-drivencompressor 2 and theevaporator 4. The inlet port of the motor-drivencompressor 2 and the exhaust port of theevaporator 4 may however be connected by a pipe. Because the length of the pipe that connects the exhaust port to the inlet port is shorter in this case too, the prevention of refrigerant leakage from the refrigerant passage between the motor-drivencompressor 2 and thecondenser 3 is improved. - At the time of connecting the unitary motor-driven
compressor 2,condenser 3 andevaporator 4 in the air-conditioning unit 1, a choice can be made between connecting thosecomponents 2 to 4 with or without pipes. - The
nipple 23 may be omitted. For example, thenipple 23 may be replaced with a structure in which one pipe section is fitted into the other pipe section and a lock nut is fastened on a external screw formed on the outer surface of the outer pipe section. - If the motor-driven
compressor 2, thecondenser 3 and theevaporator 4 are unitary as in the embodiment shown in FIGS. 3 to 4B, the means of the unification is not limited to the attachment of the components themselves. For example, thecondenser 3 to which the motor-drivencompressor 2 is attached and theevaporator 4 may be attached to a common support base or a common case. - The position and direction of the attachment of the motor-driven
compressor 2 to thecondenser 3 are variable as are the position and direction of the attachment of the motor-drivencompressor 2 to theevaporator 4. - The compressor is not limited to the motor-driven
compressor 2. For example, it is possible to employ a compressor that uses an external power source, such as an engine, as the drive source. Further, a reciprocal type compressor (e.g., a swash-plate type compressor or the like) or a rotary compressor (e.g., a scroll type compressor or the like) may be selected as needed. - The air-
conditioning unit 1 of the present invention is not necessarily be installed in a vehicle (automobile), but may be adapted to a building air-conditioning system. - It should be apparent to those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit or scope of the invention. Particularly, it should be understood that the invention may be embodied in the following forms.
- Therefore, the present examples and embodiments are to be considered as illustrative and not restrictive and the invention is not to be limited to the details given herein, but may be modified within the scope and equivalence of the appended claims.
