Abstract

The invention relates to the technical field of cabinet temperature control equipment in the communication industry, the electric power industry and the industrial control industry, in particular to a refrigeration / heat pipe composite type cabinet air conditioning system and a control method thereof.The refrigeration / heat pipe composite type cabinet air conditioning system comprises a cabinet shell, and a condenser, an outer circulation fan, a compressor, an evaporator, an inner circulation fan and a throttling variable mechanism are arranged in the cabinet shell; the throttling variable mechanism comprises a three-way valve and an electronic expansion valve. Through the automatic control system, automatic operation of the heat pipe system and the steam compression refrigeration system is realized according to different working conditions, so that the system always operates in energy-saving modes under different working conditions, the temperature in the cabinet is ensured to be in a reasonable range, the operation cost of the system is reduced, the energy consumption is reduced, and the annual comprehensive energy efficiency ratio is improved. In addition, the composite cabinet air conditioner is reasonable in structural design and simple in pipeline, and material cost is saved; intelligent automatic control operation is achieved, and operation and maintenance are convenient.

Description

technical field [0001] The invention relates to cabinet temperature control equipment in communication, electric power and industrial control industries. In particular, it relates to a refrigeration / heat pipe composite type cabinet air conditioning system and a control method thereof. Background technique [0002] Cabinet air conditioners are widely used in outdoor communication cabinets, base stations, battery cabinets, charging piles, industrial electrical control cabinets and other industries. At present, cabinet air conditioners used in domestic and foreign industries are mainly composed of cabinet shells, compressors, internal circulation fans, and external circulation fans. , condenser, evaporator, middle partition, refrigeration system connecting pipeline and control part. Its working principle: After the air conditioner is powered on, the low-pressure vapor of the refrigerant in the refrigeration system is inhaled by the compressor and compressed into high-pressure ...
