Abstract

An overhead type air conditioner of a bus comprises an air conditioner casing, a condenser core body, a condensing fan, evaporator core bodies, an evaporation fan, a compressor, a power supply and an electric control device. The evaporator core bodies and the condenser core body are arranged abreast in a left-right mode in a direction in which the bus travels, and the condenser core body is arranged in a middle cavity of the air conditioner casing, the evaporator core bodies are respectively arranged in evaporator cavities arranged on two sides of the middle cavity. The evaporation fan is arranged in the air conditioner casing arranged outside the evaporator core bodies, and the condensing fan arranged above the evaporator core bodies. The compressor is connected with the condenser core body through a pipeline, the condenser core body is connected with the evaporator core bodies through a pipeline, and the evaporator core bodies are connected with the compressor through a pipeline so as to form a circulating system in sequence. A liquid storage device, a drying device and an expansion valve are sequentially arranged on the connection pipeline of the condenser core body and the evaporator core bodies in a direction in which media flow. The overhead type air conditioner is compact and reasonable in structure, occupies little space of the top of the bus and reduces energy consumption and cost.

Description

A kind of overhead type coach air conditioner

Technical field:

The utility model relates to a kind of air-conditioning equipment, especially a kind of overhead type coach air conditioner.

Background technology:

At present, the two device assemblies (condenser assembly and evaporator assembly) of the hvac system that overhead commonly used is both at home and abroad installed are generally split type, also are to do the front and back arrangement to condenser assembly and evaporator assembly even if two devices that have are made of one formula.Be provided with like this that to take the roof space big.And it is long that two device assemblies (condenser assembly and evaporator assembly) connecting line is set like this, has that heat exchange efficiency is low, energy consumption is high.And current society, practicing thrift the material consumption and the energy is a main trend, therefore, bus market is badly in need of the new air-conditioning product that updates.At present, good solution is not also arranged.

The utility model content:

The utility model provides a kind of overhead type coach air conditioner, and its compact conformation is reasonable, and it is few to take the roof space; Shortened the connecting line between the two device assemblies; Improve the heat exchange efficiency between the two device assemblies, reduced energy consumption, practiced thrift the material consumption; Reduce cost, solved the problem that exists in the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises air conditioner housing, condenser core, condensation fan, evaporator core, evaporation fan, compressor, power supply and electric apparatus control apparatus; Said evaporator core and condenser core are set up in parallel along about the automobile direct of travel; Condenser core is arranged in the intermediate cavity of air conditioner housing, and evaporator core is arranged at respectively in the evaporator chamber of intermediate cavity both sides; In the air conditioner housing in the evaporator core outside, be provided with evaporation fan, condensation fan is arranged on the condenser core top; Compressor connects condenser core through pipeline, and condenser core connects evaporator core through pipeline, and evaporator core connects compressor through pipeline and constitutes a circulatory system successively; On the connecting line of condenser core and evaporator core, be provided with reservoir, drier and expansion valve successively by the media flow direction.

Each self-enclosed being separated by of the evaporator chamber of said intermediate cavity and both sides.

The utility model coach air conditioner compared with prior art; Have following characteristics: because evaporator core and condenser core are set up in parallel, make the overall structure compact and reasonable more of air-conditioning to take the roof space still less along about the automobile direct of travel; Practice thrift the material consumption, reduced cost; In addition, being set up in parallel of evaporator core and condenser core makes that also the connecting line between evaporimeter and the condenser shortens greatly, improved the heat exchange efficiency between evaporimeter and the condenser, reduced energy consumption.

Description of drawings:

Fig. 1 is the plan structure sketch map of the utility model coach air conditioner.

Fig. 2 overlooks the internal structure sketch map for the utility model coach air conditioner.

Fig. 3 is the syndeton sketch map of the utility model hvac system.

Among the figure, 1, the air conditioner housing; 2, condenser core; 3, condensation fan; 4, evaporation fan; 5, compressor; 6, left evaporator core; 7, right evaporator core; 8, reservoir; 9, drier 10, expansion valve; 11, intermediate cavity.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below through the specific embodiment, and combine its accompanying drawing, the utility model is set forth in detail.

Shown in Fig. 1～3; The utility model comprises air conditioner housing 1, condenser core 2, condensation fan 3, evaporator core, evaporation fan 4, compressor 5, power supply and electric apparatus control apparatus; Said evaporator core and condenser core 2 are set up in parallel along about the automobile direct of travel; Condenser core 2 is arranged in the intermediate cavity 11 at air conditioner housing 1 middle part; Evaporator core comprises left evaporator core 6 and right evaporator core 7, and left evaporator core 6 is arranged at respectively in the left evaporator chamber and right evaporator chamber of intermediate cavity 11 both sides with right evaporator core 7, each self-enclosed being separated by of left and right evaporator chamber of said intermediate cavity 11 and both sides.In the air conditioner housing 1 in the left and right evaporator core outside, be respectively arranged with evaporation fan 4, condensation fan 3 is arranged on condenser core 2 tops; Compressor 5 connects condenser core 2 through pipeline, and condenser core 2 connects evaporator core through pipeline, and evaporator core connects compressor 5 through pipeline and constitutes a circulatory system successively; On the connecting line of condenser core 2 and evaporator core, be provided with reservoir 8, drier 9 and expansion valve 10 successively by the media flow direction.

Described evaporation fan 4, condensation fan 3 and electric apparatus control apparatus are that low-voltage dc power supply drives, and compressor 5 is driven by bus engine.

Compressor 5 sucks the gaseous refrigerant of the low-temp low-pressure in left evaporator core 6, right evaporator core 7 exits, and the gas that is compressed into it HTHP is discharged compressor 5, and the superheated cold-producing medium of HTHP gets into condenser core 2 by the road; The forced flow wind speed of air cools off condenser core 2 when advancing by car, and cold-producing medium is condensed into supercooled liquid by gaseous state, discharges a large amount of heat energy to atmosphere; After the higher liquid refrigerant of temperature and pressure passed through expansion valve 10, pressure and temperature sharply descended, and it is big that volume becomes; Discharge expansion valve 10 with vapour-liquid two phase states, vapour-liquid two phase state cold-producing mediums get into left evaporator core 6, right evaporator core 7 by the road, thus the time cold-producing medium boiling point far below left evaporator core 6, right evaporator core 7 surface temperatures; So liquid refrigerant flashes to gaseous state; A large amount of heat energy that absorb in the surrounding air produce the effect on moisture extraction that cools in evaporation process, through evaporation fan 4 cold air are blown in the carriage again; Thereby; Reach the purpose of cooling in the car, then, the gaseous refrigerant of this low-temp low-pressure gets into compressor 5 again and restarts another circulation.What said process went round and began again goes on, and just can reach the purpose that continues to reduce compartment air temperature, is in the passenger car cold air to be provided through evaporation fan 4.

The utility model does not detail part, is those skilled in the art of the present technique's known technology.
