Abstract
The invention relates to an evaporation cooling-type waste heat utilization system for a supermarket showcase. The waste heat utilization system is applied to supermarket refrigerating systems, and can reasonably utilize condensed waste heat in the supermarket showcase. The system provided by the inventive patent comprises a compressor, a gas-liquid separator, an evaporator, an expansion valve, an electromagnetic valve, a liquid mirror, a drying filter, a liquid storage tank, a water-cooling stop valve, a water-cooling condenser, a water pump, a water-cooling box, an air-cooling condenser, an evaporative cooler, an air-cooling stop valve and a water tower. When a room needs to be cooled by an air conditioner, the air-cooling stop valve is closed, the water-cooling stop valve is opened, and the waste heat in the showcase can be transferred to an outdoor evaporation cooling system through the water-cooling condenser; and when the room needs to be warmed by the air conditioner, the air-cooling stop valve is opened, the water-cooling stop valve is closed, and the waste heat in the showcase can be dissipated into the room through the air-cooling condenser so as to realize heat compensation.
Description
Technical field
Patent of the present invention relates to the supermarket refrigeration system, and patent of the present invention is evaporation cold type display case waste heat utilization system.
Background technology
It is puzzlement people's a difficult problem that the used heat of the built-in unit of display case is handled always.Especially in summer and southern high-temperature area, indoor temperature needs air-conditioning system to lower the temperature, and the used heat of showcase can increase indoor temperature again, increases the thermic load of air-conditioning system, and air-conditioning just need expend more energy and come to room temperature lowering; And winter, indoor temperature needed air-conditioning system to promote temperature, and at this moment the used heat of display case can be utilized exactly.Based on this, our patent of invention evaporation cold type display case waste heat utilization system is also just arisen at the historic moment.
Summary of the invention
Goal of the invention: be the display case waste heat utilization system that a kind of energy-conserving and environment-protective are provided for market
Technical scheme: patent of the present invention is evaporation cold type display case waste heat utilization system, and it comprises compressor, gas-liquid separator, evaporimeter, expansion valve; Magnetic valve, liquid-sighting glass, device for drying and filtering, fluid reservoir; The water-cooled stop valve, water-cooled condenser, water pump, cold water case; Air-cooled condenser, evaporate cold, air-cooled stop valve, water tower.
Lower the temperature when indoor temperature needs air-conditioning, promptly indoor when not needing thermic load, kind of refrigeration cycle sucks refrigerant gas by compressor and gets into water-cooled condenser; Form the liquid fluid reservoir that gets into after the cooling refrigeration agent, liquid refrigerant is through device for drying and filtering, liquid-sighting glass; Arrive expansion valve behind the magnetic valve; Through the throttling action of expansion valve, after gas-liquid binary states entering evaporimeter gave refrigerator cooling and absorbing heat, refrigerant gas was got back to compressor through gas-liquid separator; Through the heat exchange of water-cooled condenser, realized that thermic load is to outdoor transfer; Heat up when indoor temperature needs air-conditioning, promptly indoor when needing thermic load, kind of refrigeration cycle sucks refrigerant gas by compressor and gets into air-cooled condenser; Form the liquid fluid reservoir that gets into after the cooling refrigeration agent, liquid refrigerant is through device for drying and filtering, liquid-sighting glass; Arrive expansion valve behind the magnetic valve; Through the throttling action of expansion valve, after gas-liquid binary states entering evaporimeter gave refrigerator cooling and absorbing heat, refrigerant gas was got back to compressor through gas-liquid separator; Through the heat radiation of air-cooled condenser, can be directly carry out thermal compensation to indoor; Cooling water recirculation system is pressurized to water-cooled condenser by water pump with cold water, and it is cold behind water-cooled condenser cold water absorption refrigeration agent heat, to get into evaporation, and the evaporation cooling system gives to get into behind the water for cooling that the cold water case is laggard goes into water pump, accomplishes water circulation system.
Patent advantage of the present invention: evaporation cold type display case waste heat utilization system; Can realize reasonable utilization to the showcase condensation heat; Actual use and installation etc. also more convenient; Having very strong practicality and versatility, the design of system accords with the design concept of current energy-conserving and environment-protective, and it will provide a good system product for energy-saving supermarket design in future
