Problems solved by technology

[0002] Some existing domestic automobile engine test rooms mainly use mechanical ventilation and direct exhaust, and the engine intake system also uses high-power fans to directly cool the engine temperature. It is difficult to control the temperature and humidity of the test room within a relatively stable range. Therefore, it directly affects the performance of the engine and seriously restricts the stability of the performance of domestic engines; in addition, some domestic automobile manufacturers currently use refrigeration stations to supply air-conditioning cold and heat sources, and its effect is better than that of mechanical ventilation. still unsatisfactory

Embodiment Construction

[0016] refer to Figure 1 to Figure 2 , this embodiment is a high-precision automobile engine intake air-conditioning unit with a self-contained cold source, which is composed of a unit air supply control system and a unit refrigeration bypass control system; the unit air supply control system includes an electrical control system 1, an outdoor unit 2, Indoor and outdoor connecting pipe 3, fresh air valve 4, air filter 5, internal circulation air valve 6, finned evaporator 7, heater 8, humidifier 9, blower motor 10, blower 11 and internal circulation air pipe 12; unit When the air supply control system is running, the outdoor fresh air is filtered by the fresh air inlet A11 through the fresh air valve 4 and the air filter 5 of the unit, and then enters the air conditioning unit, and then mixed with the internal circulation return air flowing out from the internal circulation return air outlet A14. The air passes through the finned evaporator 7 for cooling and dehumidification,...

Abstract

The invention relates to a high-accuracy automobile engine air inlet air conditioner unit with a cold source. The high-accuracy automobile engine air inlet air conditioner unit with the cold source is composed of a unit air supply control system and a unit refrigeration bypass control system. When the unit air supply control system runs, part of supplied air is conveyed to an engine for testing through an air supply outlet and the other part of the supplied air is adjusted through an inner circulating air returning inlet, an inner circulating air pipe and an inner circulating air valve and flows out through an inner circulating air returning outlet and then is mixed with fresh air which is filtered by an air filter through a fresh air inlet and via a fresh air valve. When the unit refrigeration bypass control system runs, one circuit of exhaust steam of a compressor is connected with a steam-liquid mixing head through a fin type condenser, a liquid feed stop valve, a drying filter and a liquid supply electromagnetic valve, the other circuit of the exhaust steam is connected with a bypass stop valve, exhaust air bypass volume of the steam-liquid mixing head from the compressor can be adjusted by the bypass stop valve. The high-accuracy automobile engine air inlet air conditioner unit with the cold source has the advantages of being high in response speed, high in control accuracy, high in efficiency, saving in energy, and capable of adapting to different weather conditions all year round, and stable in use.
