Special vehicle car air conditioner

Abstract

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...
