Abstract

The utility model relates to equipment for refrigeration and regulating indoor temperature and has the full function of refrigerators and air conditioners. All the components of the refrigerator and the air conditioner are connected by three different control valves; as a consequence, the method that when the refrigerator stops and the air conditioner or the refrigerator starts up, the air conditioner stops or crosswise operates can be adopted, and a compressor and corresponding components can be saved. The utility model has the advantages of lower price, less electric power consumption, smaller floor area, etc.

Description

Air conditioner for refrigerator

The utility model relates to the function refrigerator air-conditioner of a kind of current collection refrigerator and air-conditioner.

Now the people's refrigerator that is used to freeze and the air-conditioner that is used to regulate the room temperature be two kinds separate, not have the equipment of getting in touch, be furnished with refrigerating plant separately, therefore, shortcoming such as have that price is higher, power consumption is more, utilization rate of equipment and installations is lower and floor space is bigger.

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, and the function that a kind of current collection refrigerator and air-conditioner be provided, price is lower, power consumption is less, utilization rate of equipment and installations is higher and floor space is less refrigerator air-conditioner.

The purpose of this utility model reaches by following approach: the utility model is made up of all parts of refrigerator and air-conditioner, with the difference of refrigerator be refrigerator refrigeration and the shared compressor of air-conditioning, three six-way valves are installed in the evaporimeter of refrigerator and closed circuit capillaceous, a three-position four-way valve is installed in the condenser of heat pump type air conditioner and closed circuit capillaceous, a two-position four way change valve is installed before compressor, above-mentioned three six-way valves and three-position four-way valve, two-position four way change valve is with the evaporimeter of refrigerator and condenser and the capillary and the compressor formation refrigeration cycle of capillary and heat pump type air conditioner, by controlling three six-way valves, the relevant position of three-position four-way valve and two-position four way change valve, the repertoire of realization refrigerator and air-conditioner.

The utility model compared with prior art has following advantage:

1. all functions that refrigerator and air-conditioner are arranged.

2. owing to can take refrigerator to shut down when being incubated, when air-conditioning start or air-conditioner insulation, refrigerator start or forked working mode can be saved a compressor and corresponding component, and cost is lower.

3. the heat absorption of refrigerator and air-conditioning and heat release, but forked working utilize mutually, as being used for indoor intensification to the condenser heat of refrigerator, the evaporation heat absorption of air-conditioning is used for the refrigeration of refrigerator, and the defrost heat absorption of refrigerator is used for room temperature lowering, the condensation heat release of air-conditioning is used for the refrigerator defrost, so energy resource consumption is lower.

4. volume and floor space are less.
