Description

The difunctional refrigeration machine of refrigerator and air-conditioning

The utility model relates to a kind of compression refigerating machine with two evaporator loops, and particularly a kind of have refrigerator and a bifunctional compression refigerating machine of air-conditioning.

In existing refrigeration plant, refrigerator and air-conditioning are the refrigeration plant of two kinds of difference in functionality purposes, and they are identical on refrigeration principle.They all have the compressor as core component, and compressor all is interrupter duty, and service efficiency has only 20-30%, and from social benefit, resource utilization is too low, this type components of compressor can be united two into one fully.

Based on above-mentioned conception, the purpose of this utility model, be provide a kind of be intended to fully improve service efficiency and save social resources have two refrigeration machines of planting function of refrigerator and air-conditioning.

Solution of the present utility model is as follows.Its structure still includes casing, compressor, condenser, evaporimeter, circuit control assembly etc., and its feature part is, be divided into refrigerator and air-conditioning two parts on the structure, refrigerator part and the same compressor of air-conditioning partial common, condenser, condenser fan, receiver, two three-way electromagnetic valves and three-way magnetic valve, and refrigerator partly has oneself refrigerator capillary, evaporator of refrigerator, evaporator of refrigerator fan, and air-conditioning partly has air conditioner capillary pipe, A/C evaporator, the A/C evaporator fan of oneself; The exhaust outlet of compressor connects an end of condenser, the other end of condenser is connected with the import of receiver, the outlet of receiver is connected with two three-way electromagnetic valves, the other end of two three-way electromagnetic valves is connected with an end of air conditioner capillary pipe, the other end of air conditioner capillary pipe and the arrival end of three-way magnetic valve join, one end of an A/C evaporator and refrigerator end capillaceous is connected in the port of export of three-way magnetic valve respectively, one end of the refrigerator other end capillaceous and evaporator of refrigerator joins, the other end of A/C evaporator and the other end of evaporator of refrigerator all are connected condenser fan with the air entry of compressor, the servo respectively condenser that is installed in of evaporator of refrigerator fan and A/C evaporator fan, near evaporator of refrigerator and the A/C evaporator.

When the utility model with said structure moves under the control action of circuit control assembly, compressor is compressed into the HTHP liquid state with gaseous refrigerant and enters condenser from exhaust outlet and dispel the heat, cold-producing medium becomes the normal temperature high voltage liquid state, enter receiver again, pass through the air conditioner capillary pipe step-down then, become low-temp low-pressure, under the control of three-way magnetic valve, enter refrigerator part or air-conditioning part respectively.The cold-producing medium that enters the air-conditioning part directly carries out heat exchange by A/C evaporator, and the cold-producing medium that enters refrigerator part by the refrigerator capillary again step-down become-18 ℃ low-temp low-pressure and enter evaporator of refrigerator and carry out heat exchange, become the normal temperature low-pressure gaseous refrigerant after the heat exchange, suck compressor by air entry.

This machine is by fully adopting known refrigerator and air-conditioning electronic control technology, have following characteristics when making operation: 1. refrigerator and air-conditioning are the interleaved operation modes, partly move ten minutes as refrigerator, air-conditioning partly moves 30 minutes again, then refrigerator partly moves ten minutes, be again that air-conditioning partly moves 30 minutes again, so circulation is carried out.2. the three-way magnetic valve original state is that refrigerator part joint is logical, and air-conditioning part joint closes.Summer is by circuit controling electromagnetic valve, to reach refrigerator and air conditioner refrigerating is difunctional; When weather was felt nice and cool, the magnetic valve no power just only used refrigerator list function.3. compressor used when difunctional in summer, had only refrigerator temperature, room temperature to reach simultaneously to set just can shut down when requiring.4. mix at the cooling time branch, operate to the master to guarantee refrigerator.

The utlity model has following advantage: 1. saved resource.This machine has only been used a compressor and a cover condenser, than an independent refrigerator and an air-conditioner, saved a compressor and a cover condenser, and this machine refrigerant consumption lacks than refrigerator of equal refrigerating capacity and air-conditioner sum of adding up also.2. improved the service efficiency of compressor.The service efficiency of general air-conditioning, freezer compressor has only 20-30%, and this machine can reach 40%.3. the ratio of performance to price improves.The manufacturing cost of one playscript with stage directions utility model and selling price are easy to be accepted by market than an independent refrigerator and a manufacturing cost and the selling price reduction that air-conditioner is added up.
