Abstract
The utility model relates to a refrigeration system that economizes energy and is used for refrigerator, comprising a compressor, a condenser, a dry filter, and an electromagnetic valve for controlling pipeline, an evaporator and capillary tube for cold storage, an evaporator and capillary tube for freezing. These devices make up of pipeline of refrigeration cycle by connecting with each other. A solenoid valves for maintaining voltage is set up on the connection pipe between condenser and the electromagnetic valve for controlling pipeline. The compressor and the solenoid valves for maintaining voltage can be switched on and off synchronously. By adding the solenoid valves for maintaining voltage in the refrigeration system, the energy loss is reduced during the turn on or off the compressor, which enables to reduce energy consumption and to promote the effects of refrigeration.
Description
Technical field
The utility model relates to a kind of refrigeration system of refrigerator, especially relates to a kind of energy-saving refrigeration system of refrigerator.
Background technology
At present widespread usage constitute the refrigerator of refrigeration system by compressor, condenser, refrigeration evaporator, refrigeration capillary, refrigerating evaporator, freezing capillary, device for drying and filtering and pipeline control magnetic valve, all be that the pipeline control magnetic valve that relies on the setting of evaporimeter front end realizes that cold distributes during its work.At first detecting the refrigerator chamber temp by sensor changes, and open and close according to the start-stop of variation of temperature control compressor and the commutation of pipeline control magnetic valve, and then the control refrigerant flow that enters refrigerating evaporator or refrigeration evaporator is realized the adjustment to refrigerating chamber or refrigerating chamber.But adopt this control method, when each chamber temp reach prescribed limit, when compressor quits work, still have the pipeline of refrigerating evaporator or refrigeration evaporator to keep being communicated with condenser, because the pressure height in the condenser, therefore the high-pressure refrigerant in the condenser can continue to flow to the evaporimeter that communicates, the cold-producing medium heat absorption back temperature that enters evaporimeter raises and loses refrigeration gradually, causes the loss of cold and then causes energy dissipation.And the pressure reduction that condenser loss refrigerant pressure reduces between back and evaporimeter reduces, when compressor starts again, the pressure reduction that need utilize a period of time to rebulid between condenser and evaporimeter could realize that refrigeration system enters normal kind of refrigeration cycle once more, reduce refrigerating efficiency, and caused the waste of energy again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of energy-saving refrigeration system of refrigerator is provided.
The utility model is to realize like this, comprise the refrigerating circulation that is interconnected to constitute by compressor, condenser, device for drying and filtering, pipeline control magnetic valve, refrigeration evaporator, refrigeration capillary, refrigerating evaporator, freezing capillary, on the connecting line between condenser and the pipeline control magnetic valve, the pressurize magnetic valve is set, and makes pressurize magnetic valve and compressor open synchronously or close.
Use the utility model, utilize and in refrigeration system, set up the pressurize magnetic valve, effectively reduced the loss and waste of energy in compressor unlatching or the stopping process, thereby reached the effect that cuts down the consumption of energy, improves refrigerating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the energy-saving refrigeration system of the utility model refrigerator comprises compressor 1, control piper magnetic valve 2, pressurize magnetic valve 3, condenser 4, refrigeration evaporator 5, refrigeration capillary 6, refrigerating evaporator 7, freezing capillary 8 and device for drying and filtering 9, and they are interconnected to constitute a refrigerating circulation.
When refrigerator needed refrigeration system work, compressor 1 started, and pressurize magnetic valve 3 is in opening state thereupon.Under the driving of compressor, cold-producing medium is pressed towards condenser 4, condenser 4 internal pressures are raise, cold-producing medium outwards dispels the heat in condenser 4 and becomes liquid phase by gas phase, because evaporator pressure is low, the cold-producing medium in the condenser flow through device for drying and filtering 9, pressurize magnetic valve 3, and pass through the allotment of control piper magnetic valve 2 according to the actual refrigeration demand of refrigerator chamber, or enter refrigeration evaporator 5, or enter refrigerating evaporator 7 by freezing capillary 8 by refrigeration capillary 6 throttlings.The heat that enters the cold-producing medium absorption refrigerator chamber of evaporimeter is gasified again, finally is recovered the suction compressor along pipeline, and so circulation realizes refrigeration.When the refrigerator chamber temp all reaches setting value, compressor 1 quits work, meanwhile pressurize magnetic valve 3 cuts out, blocking-up condenser 4 is communicated with refrigeration evaporator 5 and refrigerating evaporator 7, avoid the high-pressure refrigerant in the condenser 4 to continue to flow into the cool amount loss that evaporimeter forms, keep the pressure reduction between condenser and evaporimeter simultaneously, when compressor starts once more, refrigeration system can the normal kind of refrigeration cycle of very fast recovery and be need not for a long time pressure accumulation again, thereby reaches the purpose of energy savings.
Compared with the prior art, the utility model is by setting up the pressurize magnetic valve in refrigerator refrigeration system, and then avoided compressor to quit work energy loss that cold in the post-condenser runs off and form, and, the pressure differential between condenser and evaporimeter rebulid the energy dissipation that pressure reduction causes because of reducing a period of time of need turning round when the compressor cause starts once more, therefore energy-saving effect is obvious, refrigerating efficiency is higher, and with low cost, and is safe and reliable.
