Novel dual-purpose refrigeration air conditioner system for driving/parking

Abstract

The invention discloses a novel dual-purpose refrigeration air conditioner system for driving / parking. The novel dual-purpose refrigeration air conditioner system for driving / parking comprises a controller, a first compressor, a second compressor, a condenser, a reservoir, an expansion valve, an evaporator and a storage battery. The first compressor, the condenser, the reservoir and the expansionvalve are connected with the evaporator in sequence to form a first return circuit. The second compressor, the condenser, the reservoir, the expansion valve and the evaporator are connected in sequence to form a second return circuit. The storage battery is connected with the second compressor. A cooling fan is arranged on one side of the condenser. When the controller detects a rotating speed signal of an engine, the controller conducts the first return circuit and cuts off the second return circuit, the engine drives the first compressor to work, and the system is in the driving refrigeration mode at present. When the rotating speed signal of the engine is not detected by the controller, the controller cuts off the first return circuit and conducts the second return circuit, the storagebattery powers the second compressor to drive the second compressor to work, and the system is in the parking refrigeration mode at present.

Description

Technical field [0001] The invention relates to the technical field of vehicle refrigeration control, in particular to a novel driving / parking dual-purpose refrigeration and air-conditioning system. Background technique [0002] At present, the air-conditioning products for up-car refrigeration in the market are mature and common, but there are few air-conditioning products used for parking refrigeration in actual use, and there is no consensus on the product form in the industry. As we all know, the compressor of the existing car air-conditioning system is powered by the engine, so in the driving mode, that is, when the car engine is running, it can still work normally, but in the parking mode, that is, when the car engine is not running, because There is no power source, so the air conditioning system cannot be turned on, so that the temperature inside the car will rise sharply in summer. If you want to turn on the system, the car engine needs to keep running, which wastes ene...

Problems solved by technology

[0004] However, the problem with the above method is that the system is relatively complex and costly, and may have potential safety hazards

On the one hand, whether it is to increase the independent all-in-one machine, or increase the related inverter, solar power generation equipment and some other electronic control parts, it will greatly increase the number of components, complicate the system, and increase the cost

On the other hand, the use of external power or solar energy is limited in usage scenarios; if an inverter is used, the power efficiency of the entire system will be reduced

In addition, introducing high voltage into the car also has certain potential safety hazards.
