Refrigeration system

Abstract

The invention discloses a refrigeration system, and provides the refrigeration system using a valve to adjust a refrigeration amount. An exhaust opening of a compressor is respectively connected with a first valve and a second valve; the first valve is connected with a condenser for heat exchange; the second valve is connected with a condenser for balancing; an outlet of the condenser for heat exchange is connected with a throttling device after being connected in parallel to an outlet of the condenser for balancing; the throttling device is connected with an evaporator; the evaporator is connected with an air suction opening of the compressor; the condenser for balancing and the evaporator are mounted in parallel to form a group of heat exchange devices; in a refrigeration circulating process, the second valve is closed and the first valve is opened; if the refrigeration amount needs to be adjusted, the first valve and the second valve are opened; the opening degrees of the first valve and the second valve can be adjusted, or the opening time period of the first valve and the second valve can be adjusted; the amounts of refrigerating fluid entering the condenser for the heat exchange and the condenser for balancing can be adjusted; and the condensed refrigerating fluid vapor in the condenser for balancing is subjected to heat radiation to the evaporator, so that the amount of the refrigerating fluid can be adjusted.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system. Background technique [0002] At present, in order to meet the needs of technology or comfort for precise temperature, in the refrigeration system, the precise control of the cooling capacity is realized by adjusting the output of the compressor. For example, by changing the power supply frequency of the AC motor to adjust the output of the AC compressor, or by changing the power supply voltage of the DC motor to adjust the output of the DC compressor, or by adjusting the valve to communicate with the suction and exhaust ports of the compressor to form a load and unload. Adjust the output of the compressor. The systems involved in these regulation methods are complex in structure, high in cost, and large in electrical power loss, which is not conducive to miniaturization and is difficult to apply to low-temperature systems. [0003] Another method ...

Problems solved by technology

The system structure involved in these adjustment methods is complex, the cost is high, the electric power loss is large, it is not conducive to miniaturization, and it is difficult to apply to low temperature systems

[0003] Another method to meet the precise temperature control is to balance the cooling capacity of the compressor by means of electric heating. This system consumes a lot of power and has a low energy efficiency ratio.
