Problems solved by technology

[0003] When the current condensing unit works in winter, due to the low outdoor temperature, it is easy to make the pressure in the condensing unit lower than the minimum working pressure of the compressor, which causes the compressor to stop working. Moreover, when the outdoor temperature is low, the evaporation If the refrigeration load of the condenser is reduced, it is also easy to cause the compressor to stop working and affect the normal operation of the condensing unit.

Abstract

The invention discloses a condensing unit, and belongs to the technical field of refrigerating devices. The condensing unit comprises a compressor, a condensing unit, a liquid storage device and an evaporator which are sequentially connected through a first pipeline to form a circulation loop; a pressure regulator is arranged between the condensing device and the liquid storage device, and the first pipeline is filled with a refrigerant; the condensing unit further comprises a second pipeline and the first pipeline, one end of the second pipeline is connected to the compressor, the other end of the second pipeline is connected to the liquid storage device, and a first control valve is arranged on the second pipeline; and one end of a third pipeline is connected to the compressor, the otherend of the third pipeline is connected to the evaporator, and an energy regulator is arranged on the third pipeline. According to the condensing unit, the second pipeline and the third pipeline are arranged, the first control valve is arranged on the second pipeline, the energy regulator is arranged on the third pipeline, the first control valve, the pressure regulator and the energy regulator are act jointly, so that the compressor can still be always in a working state when the temperature in the outdoor environment is low, and the compressor is prevented from being stopped.

Description

technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a condensing unit. Background technique [0002] The condensing unit includes a condenser, a compressor, and an evaporator. The three are connected to each other through pipelines, and the pipelines are filled with refrigerant. The evaporator is located indoors, while the compressor and condenser are located outdoors. The liquid refrigerant is in the evaporator. The internal heat is absorbed and gasified into a high-temperature gas, and the high-temperature gas enters the condenser through the compressor to release heat and then turns into a liquid refrigerant to realize the cooling of the room. [0003] When the current condensing unit works in winter, due to the low outdoor temperature, it is easy to make the pressure in the condensing unit lower than the minimum working pressure of the compressor, which causes the compressor to stop working. Moreover, when the ou...
