Method and system for controlling operation of constant-frequency air conditioner for base station

Abstract

The invention is applicable to the air conditioner technical field and provides a method and system for controlling the operation of a constant-frequency air conditioner for a base station and the constant-frequency air conditioner for a base station. The method comprises the following steps: detecting the current indoor temperature, and when the current indoor temperature is higher than a preset temperature and reaches the upper limit of the control accuracy of the preset temperature, controlling a starting compressor to start refrigeration, wherein the upper limit is more than 1 DEG C and can be set to be more than 3-6 DEG C through programming. The temperature control range for the operation of the compressor is wider compared with the prior art, thus reducing the start-stop frequency of the compressor; the lower limit of the control accuracy of the preset temperature is equal to 0 DEG C, the air conditioner stops when reaching the preset temperature, when the lower limit is increased too, the operation temperature of the compressor is increased so that the compressor exhausts less power and further reaches the effect of energy-saving, compared with the prior art; and the preset temperature can also be increased to reduce the power consumption of the compressor and further satisfy the aim of energy-saving.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method and system for controlling the operation of a fixed-frequency air conditioner for a base station and a fixed-frequency air conditioner for a base station. Background technique [0002] According to statistics, the power consumption of communication base stations accounts for 73% of the total energy consumption of mobile communication operators, while the energy consumption of base station air conditioners accounts for 50% of the total energy consumption of base stations. Top priority at work. [0003] At present, there are mainly three throttling methods for fixed-frequency air-conditioning evaporators. The first is to use capillary throttling to circulate refrigeration. This method adopts fixed design conditions and pre-calculates the evaporation pressure and evaporation temperature of the refrigerant. The capillary flow rate cannot be adjusted. Tu...
