Embodiment Construction

[0019] Such as figure 1 As shown, a year-round refrigeration system includes a compressor, a condenser, a liquid receiver, a throttling device, and an evaporator connected by pipelines. The condenser is provided with a condensing fan, and at least two condensers are arranged in parallel , the condensing fan of the condenser adopts a frequency conversion fan, and the inlet of the condenser is provided with a solenoid valve to control the on-off of the condenser. The throttling device includes a throttle valve and an electronic expansion valve, and a stop valve and a solenoid valve are arranged on both sides of the throttle valve.

[0020] The compressor sucks the lower-pressure working medium vapor from the evaporator, raises its pressure, and sends it to the condenser, where it is condensed into a liquid with higher pressure. After being throttled by the throttling device, it becomes After the low-pressure liquid is sent to the evaporator, it absorbs heat and evaporates in th...

Abstract

The invention discloses a year-round cooling system. The year-round cooling system comprises a compressor, at least two condensers, a throttling device and an evaporator which are connected through a pipeline. Each condenser is provided with a condensing fan. The condensers are arranged in parallel. A variable frequency fan is used as the condensing fan of each condenser. An electromagnetic valve is arranged at an inlet of each condenser and used for controlling switching-on and switching-off of the condenser. A condensing pressure adjusting valve is arranged at an outlet of each condenser. According to the year-round cooling system, the condensing air volume is controlled through frequency conversion of the fans and starting and stopping of the grouped fans, so that enough condensing pressure is maintained, the cooling requirement in a low-temperature environment is met, and the problem that operation is unstable under a year-round cooling condition is solved.

Description

technical field [0001] The present invention relates to refrigeration systems. Background technique [0002] Existing air-cooled chillers for year-round refrigeration often achieve limited year-round cooling demand by controlling the condensing fan, but they cannot meet the cooling requirements of low-temperature environments in winter in northern regions (for example: -40°C), and those with special comfort and process requirements Occasions (such as: nuclear power plants), and commonly used air-cooled chillers operate unstable under year-round cooling conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a year-round refrigeration system, which can meet the refrigeration requirements in a low-temperature environment and solve the problem of unstable operation under year-round refrigeration conditions. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the follo...
