Abstract
The invention relates to a water-cooling machine set type system for utilizing supermarket display cabinet waste heat. The system is applied to a supermarket refrigerating system, and the supermarket display cabinet condensation waste heat can be reasonably used. The water-cooling machine set type system comprises a compressor, a gas-liquid separator, an evaporator, an expansion valve, a solenoid valve, a visual liquid mirror, a drying filter, a liquid storage tank, a water-cooling stop valve, a water-cooling condenser, a water pump, a water-cooling tank, an air-cooling condenser, a water-cooling machine set and an air-cooling stop valve. When an air conditioner is needed for cooling indoors, by closing the air-cooling stop valve and opening the water-cooling stop valve, the display cabinet waste heat can be transferred to the outdoor water-cooling machine set through the water-cooling condenser; and when the air conditioner is needed for warming indoors, by opening the air-cooling stop valve and closing the water-cooling stop valve, the display cabinet waste heat can be transferred indoors through the air-cooling condenser to dissipate heat, and heat compensation is achieved.
Description
Technical field
Patent of the present invention relates to Refrigeration System in Supermarkets, and patent of the present invention is water chiller formula 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 processed 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 to expend more energy to be 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 water chiller formula 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 water chiller formula 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, the cold water case, air-cooled condenser, handpiece Water Chilling Units, air-cooled stop valve etc.
When needing air-conditioning, indoor temperature lowers the temperature, be indoor when not needing thermic load, kind of refrigeration cycle sucks refrigerant gas by compressor and enters water-cooled condenser, form liquid state after the cooling refrigeration agent and enter fluid reservoir, liquid refrigerant passes through device for drying and filtering, liquid-sighting glass, arrive expansion valve behind the magnetic valve, throttling action by expansion valve, after the gas-liquid binary states enters evaporimeter and gives refrigerator cooling and absorbing heat, refrigerant gas is got back to compressor through gas-liquid separator, by the heat exchange of water-cooled condenser, has realized that thermic load is to outdoor transfer; When needing air-conditioning, indoor temperature heats up, be indoor when needing thermic load, kind of refrigeration cycle sucks refrigerant gas by compressor and enters air-cooled condenser, form liquid state after the cooling refrigeration agent and enter fluid reservoir, liquid refrigerant passes through device for drying and filtering, liquid-sighting glass, arrive expansion valve behind the magnetic valve, throttling action by expansion valve, after the gas-liquid binary states enters evaporimeter and gives refrigerator cooling and absorbing heat, refrigerant gas is got back to compressor through gas-liquid separator, by the heat radiation of air-cooled condenser, can be directly carries out thermal compensation to indoor; Cooling water recirculation system is pressurized to water-cooled condenser by water pump with cold water, enters handpiece Water Chilling Units behind water-cooled condenser cold water absorption refrigeration agent heat, and handpiece Water Chilling Units gives to enter behind the water for cooling that the cold water case is laggard enters water pump, finishes water circulation system.
Patent advantage of the present invention: water chiller formula display case waste heat utilization system, can realize the 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
