Problems solved by technology

The working time in winter with low ambient temperature is almost the same as that in summer with high ambient temperature. Only using compressor for cooling will not only waste electric energy but also affect the working life of the unit

Abstract

The invention discloses an energy-saving refrigerator unit, comprising refrigerating cycle devices of cooler and load cycle installation for users, refrigerating cycle devices of cooler connects the compressor and condenser, condenser is connected with cooling devices, load cycle installation for users link thermal load and evaporator, the cooler cycle devices and load cycle installation exchange heat through evaporator, the said load cycle installation also connects a auxiliary heat exchanger at the upstream position of coolant flow to evaporator, the auxiliary heat exchanger and condenser are parallel connected to the cooling device, the load cycle devices and cooling device can also exchange heat through assisted heat exchanger. The invention can apply natural cooling cycle for spontaneous heat transfer in the ambient conditions with lower temperatures, or simultaneous use with cold mechanism and the cold cycle, save a lot of electricity, extend the service life of equipment, can also be compound used each other to improve the reliability of cooling.

Description

technical field [0001] The invention relates to an energy-saving refrigeration unit. Background technique [0002] Refrigeration units are widely used in civil or industrial and mining air-conditioning systems or industrial refrigeration equipment. These refrigeration units generally include two parts: chiller refrigeration cycle device and user load cycle device. Refrigeration cycle device includes compressor and condenser. There are two parts of the condenser, and the condenser is connected with a cooling device such as a cooling water tower or a cooling fan. The compressor compresses the refrigerant from the user's load circulation device and sends it to the condenser for condensation. After the exchange, it is throttled into a low-temperature and low-pressure refrigerant, and then it is sent to the evaporator of the user load cycle device, and the evaporator cools the user load and the indoor environment to control the temperature and humidity.
