Improved steam compression type refrigeration system and uses thereof

Abstract

Disclosed is an improved vapor compression type refrigerating system and the purpose. The system is composed of main parts of a compressor, a four-way reversing solenoid valve which is installed or not, a condenser, a device for drying and filtering, a throttle valve, an evaporator and a gas-liquid separator, and is suitable for heat and cool producing devices of cool-warm air conditioner, hot-air pump water heater, drying house, refrigerator and the like. The invention is characterized in that in the system, all condensers are equipped with thermo-regulators, when cold water in the condensers is heated to 40 DEG C by heat of condensation, the thermo-regulators lead the 40 DEG C low-temperature hot water to a heat-insulating water tank by a control system, then the water is heated into 70DEG C bath and living hot water by solar energy when it is sunny and by a thermal pumping when it is rainy, thereby when the system serves as a refrigerating air conditioner, hot water is simultaneously prepared, refrigerating effect is not influenced, and two parts of benefits are obtained with one part of electric power, a win-win situation of energy saving and discharge reducing is achieved, further a sub-cooler is installed between the device for drying and filtering and the throttle valve, additionally in the system, the heat and cool producing devices are grafted into multifunctional composite units which share a part of parts by a three-way reversing solenoid valve, thereby saving raw materials and reducing general cost.

Description

technical field [0001] The present invention relates to a vapor compression refrigeration system and its application, in particular to a cluster of improved vapor compression refrigeration systems and its application, which is suitable for providing households and units with hot water for washing and living, drinking water, heating in winter, and heating in summer. Air conditioning; or hot water and boiling water for industrial and agricultural production, and can also provide cooling capacity for refrigerators, freezers, or refrigerators; provide heating capacity for drying rooms. Background technique [0002] The vapor compression refrigeration system of the existing refrigeration and heating equipment is not equipped with a subcooler, and its refrigeration coefficient and heat supply coefficient are not large enough. In addition, the existing heat pump water heater needs to have an outdoor unit used as an evaporator and an outdoor unit used as an evaporator. The condenser...

Problems solved by technology

[0002] The vapor compression refrigeration system of the existing refrigeration and heating equipment is not equipped with a subcooler, and its refrigeration coefficient and heat supply coefficient are not large enough. In addition, the existing heat pump water heater needs to have an outdoor unit used as an evaporator and an outdoor unit used as an evaporator. The condenser and heat pump water tank of the heat pump water heater, and the existing air conditioner also needs to have an indoor unit that is used as an evaporator in summer and a condenser in winter, and an outdoor unit that is used as a condenser in summer and an evaporator in winter. If the air conditioner and the heat pump water heater can be grafted and combined to form a compound unit, in summer, it can not only cool the air conditioner, but also produce hot water at the same time, only consume one part of electricity, and get two benefits, which is double energy saving and emission reduction. It also saves the total cost and saves an outdoor unit. However, when the air conditioner is cooling the air conditioner, the condensing temperature of the refrigerant is usually 40 ° C ~ 45 ° C, and the heat pump water heater produces hot water. The condensing temperature is as high as 70°C. If the two are grafted together, the cooling air conditioner will produce hot water at the same time in summer. If the condensing temperature rises to 70°C, the cooling capacity will decrease, the power consumption will increase, the cooling coefficient will become smaller, and the cooling effect will be poor. The good dream failed to come true, and the present invention overcomes this technical problem
