Abstract

The embodiment of the invention provides an environment test device based on suction superheat degree and air volume partition and a control method thereof. The environment test device comprises a compressor, an evaporator and a temperature sensor, wherein the compressor and the evaporator are connected through a pipeline, the temperature sensor is arranged on the pipeline, and the temperature sensor is positioned on the upstream of the inlet end of the compressor; a fan capable of adjusting the output air volume is arranged on one side of the evaporator, and the rotating speed of the fan is controlled by a control module; and the control module is used for matching the target superheat degree in a preset data set based on the current suction temperature collected by the temperature sensor, and controlling the fan to be adjusted to the target air volume according to the matched target superheat degree. According to the environment test device based on the suction superheat degree and the air volume partition and the control method thereof, the system is in an optimal flow operation state by controlling the suction superheat degree partition control and the air volume partition control, so that the superheat degree of the system is guaranteed, the liquid impact of the compressor is prevented, and the purpose of energy conservation can be achieved.

Description

technical field [0001] The invention relates to the field of environmental testing equipment, in particular to an environmental testing equipment based on suction superheat and air volume zoning and a control method thereof. Background technique [0002] For environmental test equipment, the system flow is often controlled by load requirements, but generally lacks control over superheat. As a result, the compressor may suffer liquid shock, or the lubricating effect of the lubricating oil may decrease, resulting in damage to the compressor. [0003] Specifically, if the overheating is too high, the lubricating effect of the lubricating oil will decrease, resulting in carbonization of the lubricating oil and serious wear of the compressor. On the contrary, if the superheat is too low, the concentration of lubricating oil will drop, which may lead to liquid back in the system, and the liquid hammer will cause damage to the compressor. Contents of the invention [0004] In v...
