Abstract

The invention relates to an intelligent three-source frostless refrigerating system comprising a compressor, a condenser and an evaporator. The compressor communicates with the condenser through an air exhaust pipe. The compressor communicates with the evaporator through an air suction pipe. The condenser communicates with the evaporator through a liquid supplying pipe. A first liquid supplying solenoid valve is arranged on the liquid supplying pipe. An air exhaust outlet of the compressor communicates with a liquid inlet of the evaporator. A first air exhaust solenoid valve is mounted on a first branch pipe. A liquid discharge outlet of the condenser communicates with the liquid inlet of the evaporator. A second liquid supplying solenoid valve is mounted on a second branch pipe. A servo valve is mounted on the liquid supplying pipe. The valves are connected with a controller. The controller is connected with at least one environment temperature probe used for detecting the environment temperature. The refrigerating system can provide three refrigerating agents with different states for the evaporator, accordingly the problem of frosting of the evaporator is solved, and the refrigerating effect and the refrigerating efficiency under the low environment are improved.

Description

Technical field [0001] The invention relates to the field of refrigeration, in particular to an intelligent three-source frost-free refrigeration system. Background technique [0002] The general refrigeration principle of a refrigerator is: the refrigerant absorbs heat in the evaporator in a liquid state for cooling, the low-temperature liquid absorbs the latent heat of vaporization and becomes the refrigerant gas, which is sucked in and compressed by the compressor, and the pressure and temperature of the compressed gas increase, and then flow into Condenser, the condenser condenses the refrigerant gas in the form of air-cooled and water-cooled. The condensed high-temperature and high-pressure liquid is stored at the bottom of the condenser and in the reservoir. The heat released during condensation is taken out and dissipated by equipment such as fans and water pumps. In the environment, when the high-temperature and high-pressure liquid flows through the expansion valve, it e...
