Adaptive control system for condensing fan of air conditioner with dual-circuit heat pipe for cooling in computer room

Abstract

The invention relates to the technical field of air conditioning, and discloses an adaptive control system for a condensing fan of a computer room refrigeration dual-circuit heat pipe air conditioner.The system comprises an outdoor temperature collector, an indoor temperature collector, a refrigerant pipe condensation pressure sensor, an external fan and a controller. The controller is electrically connected with the outdoor temperature collector, the indoor temperature collector and the refrigerant pipe condensation pressure sensor. The system provided by the invention has the advantages that the controller compares the indoor and outdoor temperature difference with a preset temperature value; when the indoor and outdoor temperature difference is greater than or equal to the preset temperature value, a heat pipe system runs, and the controller controls the operation of the external fan according to the indoor and outdoor temperature difference; when the indoor and outdoor temperaturedifference is less than the preset temperature value, an air conditioning system runs, and the controller controls the operation of the external fan according to the condensation pressure of a refrigerant pipe; the system automatically adjusts the external fan to realize the condensing and heat transfer of a condenser according to the operating status of the refrigeration dual-circuit heat pipe air conditioner, so as to automatically adjust the operation of the external fan and save energy.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an adaptive control system for cooling fans of an air conditioner with double-circuit heat pipes for cooling in a machine room. Background technique [0002] A computer room, such as a communication computer room, is densely arranged with communication equipment and power supply equipment inside. The equipment generates a lot of heat, and the equipment keeps running all year round and is in a closed space. larger. The traditional computer room air conditioner includes an indoor unit and an outdoor unit. The indoor unit is equipped with an evaporator, and the outdoor unit is equipped with a condenser and an external fan for condensation. After the refrigerant evaporates and exchanges heat in the evaporator of the indoor unit, it passes through the compressor, copper tube Into the condenser, the external fan for condensation runs, and the outdoor air passes through the co...

AI Technical Summary

Problems solved by technology

The existing control method of the condensing external fan is no longer applicable to the heat pipe air conditioner. Therefore, it is necessary to provide an adaptive control system for the condensing fan of the machine room cooling dual-circuit heat pipe air conditioner, which can control the operation of the external fan according to the operating status of the cooling dual-circuit heat pipe air conditioner.
