Problems solved by technology

In this way, the refrigerant generally enters the compressor in a superheated state, and the volume of the refrigerant expands greatly, that is, the specific volume increases, so that the quality of the refrigerant that actually participates in the refrigeration cycle is relatively reduced; on the premise that the input power of the compressor is determined, the compression In order to achieve refrigeration, the machine must ensure a certain compression ratio, so the air transmission volume of the refrigeration system becomes smaller. At the same time, there is friction between the compressor shaft and the support bearing during operation, and the input power of the motor is small, and the compressor heats up. The capacity is reduced, and when the working environment of the compressor is bad, the efficiency of the refrigeration equipment is extremely low, and even cannot be used normally

Abstract

The invention discloses a freezer used turbine pressurizing device, which includes a middle shell body, and a low-pressure turbine part and a driving part respectively arranged on two sides of the middle shell body. The driving part also drives a turbine shaft inside. The turbine shaft which axially passes through the middle shell body from the driving part is connected with a rotation part in the low-pressure turbine part. The invention is arranged on the suction opening side of the compressor, is driven by the exhaust of the freezing system or the external power, improves the gas output of the compressor, increases the circulating volume of the refrigerant, and improves the refrigeration volume and the refrigeration efficiency of the freezer.

Description

technical field [0001] The invention relates to a turbocharging device for a refrigerator. Background technique [0002] At present, when a common vapor compression refrigerator performs a refrigeration cycle, the refrigerant evaporates and is inhaled by the compressor in a gaseous state, then enters the heat exchanger after being compressed, and then passes through a throttling device or an expander (usually a constant flow throttling mechanism) (such as capillary) mostly to achieve refrigeration) to complete the cycle. In this way, the refrigerant generally enters the compressor in a superheated state, and the volume of the refrigerant expands greatly, that is, the specific volume increases, so that the quality of the refrigerant that actually participates in the refrigeration cycle is relatively reduced; on the premise that the input power of the compressor is determined, the compression In order to achieve refrigeration, the machine must ensure a certain compression rat...
