Problems solved by technology

[0004] Fixed-frequency air conditioners operate at a fixed grid frequency, and the starting current of the compressor is 3-5 times the normal operating current. When the temperature reaches the set value, the air conditioner using the fixed-frequency compressor can only control the compressor to "stop" and "start". To adjust the indoor temperature, it is not only easy to cause the room temperature to fluctuate, but also consumes a lot of power and starts a large current

Embodiment Construction

[0023] see figure 1 , a DC frequency conversion vehicle air conditioner, including a compressor 1, a condenser 2 and an evaporator 4 which are sequentially connected through pipelines, and the connecting pipeline between the condenser 2 and the evaporator 4 is connected with a device for controlling the flow of refrigerant A gas-liquid separator 5 is connected to the connecting pipeline between the capillary 3, the evaporator 4 and the compressor 1 .

[0024] In the present invention, one side of the evaporator 4 is provided with an evaporator fan 6 for circulating ventilation and cooling, and performs ventilation and circulation to the equipment or space to be cooled.

[0025] One side of the condenser 2 is provided with an axial flow fan 7 for taking away the heat of the condenser, so as to speed up the working efficiency of the condenser 2 .

[0026] Compressor 1 adopts a DC inverter compressor.

[0027] The present invention will be further described below in conjunction...

Abstract

The invention discloses a direct-current variable-frequency vehicle-mounted air conditioner which comprises a compressor, a condenser and an evaporator which are sequentially and cyclically connected through a pipeline. A capillary tube is connected with the connecting pipeline between the condenser and the evaporator, and a gas-liquid separator is connected with the connecting pipeline between the evaporator and the compressor. The direct-current variable-frequency vehicle-mounted air condition is simple in structure, mature in refrigeration system technology, easy to manufacture, high in reliability, wide in application and widely applicable to vehicle-mounted air condition using mains supply or oil engines for power supply, and problems that the vehicle-mounted air conditioner loses power source due to long-term shutdown and passengers or electronic equipment standing in a vehicle need to have temperature regulated are effectively solved.

Description

technical field [0001] The invention relates to the technical field of cooling capacity adjustment of a vehicle-mounted air conditioner, in particular to a DC frequency conversion vehicle-mounted air conditioner. Background technique [0002] With the development of modern technology, vehicle air conditioners are widely used to provide a working environment with a suitable temperature for the staff in the cab and the equipment in the vehicle. Generally, the car air conditioner uses the car compressor to provide the power source, and the engine pulley drives the compressor clutch to rotate, together with the condenser, evaporator, condensing fan and evaporator fan, etc. The realization of refrigeration cannot meet the needs of long-term vehicle parking and temperature regulation of the occupants or electronic equipment, and the use of other methods of refrigeration will become an inevitable demand. [0003] Due to the limitations of the use environment and conditions of use,...
