Problems solved by technology
[0002] The cab structure of some special vehicles is quite special. The middle part of the cab body is concave, and the two sides of the concave shape behind the cab only have a space of 650㎜×700㎜×250㎜ (length×height×thickness), which is limited by the space structure. It is impossible to install integrated air conditioners such as interior and exterior top mounts and wall mounts that meet the temperature regulation capabilities
The air conditioner adopts the split structure of indoor and outdoor units, and because there are many external refrigerant pipelines and high-voltage cables are scattered, there are hidden dangers of easy leakage and low electrical safety assurance

Embodiment Construction
[0015] Such as figure 1 , figure 2 , image 3 , Figure 4 shown. The vehicle-mounted air conditioner for a special vehicle of the present invention comprises two independent air-conditioning units and a temperature-adjusting controller on the left and right. Among them, each air conditioning unit is composed of evaporator, evaporator fan, PTC electric heater, expansion valve 2, integrated scroll electric compressor 3, first parallel flow condenser 4, dry liquid receiver assembly 5, integrated A drive circuit 7, a second parallel flow condenser 8 and a housing assembly 9 are formed. The housing assembly 9 includes a rectangular housing and a cover plate. The housing is a rectangular housing with openings on the upper end surface and the outer surface. The cover plate is an L-shaped cover plate corresponding to the upper end surface and the outer surface of the housing. The two sides of the housing There are fixed ears on the side, and the fixed ears are used for the insta...

The invention provides a vehicle-mounted air conditioner for a special vehicle and belongs to the technical field of vehicle-mounted air conditioners. The vehicle-mounted air conditioner mainly solves the problem that an existing concave cab is limited by the installation space and consequently a corresponding air conditioner is difficult to arrange to meet the temperature adjusting requirement. The vehicle-mounted air conditioner is mainly characterized by comprising a left independent air conditioning unit, a right independent air conditioning unit and a temperature adjusting controller; evaporators, evaporator draught fans and PTC electric heaters are arranged in indoor unit assemblies above shells; expansion valves are arranged on cover boards of the indoor unit assemblies; integrated vortex motor compressors and integrated drive circuits are arranged at the middle lower portions of the shells side by side; drying liquid storage device assemblies and first parallel flow condensers are arranged below the shells; second parallel flow condensers are arranged on the sides of the shells; the shells are provided with condensate fans; and ventilation windows are formed in the shells and the cover boards. The vehicle-mounted air conditioner has the beneficial effects that devices in the units are concentrated, and safety and reliability are high; and the vehicle-mounted air conditioner is mainly used for a cab with the middle portion of a vehicle body concave.
Description
technical field [0001] The invention belongs to the technical field of vehicle-mounted air conditioners, and in particular relates to a high-voltage DC vehicle-mounted air conditioner for cabs or shelters with limited installation space. Background technique [0002] The cab structure of some special vehicles is quite special. The middle part of the cab body is concave, and the two sides of the concave shape behind the cab only have a space of 650㎜×700㎜×250㎜ (length×height×thickness), which is limited by the space structure. It is impossible to install integrated air conditioners such as interior and exterior top mounts and wall mounts that meet the temperature regulation capabilities. The air conditioner adopts the split structure of indoor and outdoor units, and because there are many external refrigerant pipelines and scattered high-voltage cables, there are hidden dangers of easy leakage and low electrical safety guarantee. It is the key point of the present invention t...
