A speed regulation control method of an air conditioner outdoor fan

Abstract

The invention discloses a speed regulation control method of air conditioner outdoor fan. The method uses the temperature of conditioner outdoor coil pipe to reflect the system pressure. The RPM regulation and control strategy of the outdoor fan is designed base on the combinational factors of changes of the outdoor environmental temperature and the outdoor coil pipe temperature. Through the control of outdoor fan RPM the outdoor coil pipe temperature can be regulated. Through controlling the outdoor coil pipe temperature within the set range of temperature the system pressure can be stabilized within the scope of the reliable operation of the compressor, therefore the safe operation of the compressor can be guaranteed. Because the precise regulation of the PRM of the outdoor fan can be achieved without the unnecessary pressure sensor installation in the air conditioner system for collecting the system pressure, so the accruement of hardware cost of the product can be avoided. At the same time the stepless speed regulation is used in the outdoor fan to enhance the stability of the system pressure control, and improve the air conditioning system work performance. The method is especially useful for the base station air conditioner to enhance the system operation reliability of the base station air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, in particular, it is a fan speed control method proposed for an outdoor fan of a base station air-conditioning system. Background technique [0002] With the acceleration of the popularization of smart phones, the increase of users' demand for mobile communication, 4G change and "Internet +" trend and other factors, the construction scale of the base station as a communication infrastructure is rapidly expanding. In order to stabilize the ambient temperature inside the communication base station and ensure the safe operation of the communication equipment in the computer room, the installation and use of the base station air conditioner is very important. [0003] Base station air conditioners are mainly used to control the temperature and humidity inside the base station. From the perspective of actual application, there are mainly two types of traditional floor-mounted base sta...

Problems solved by technology

Since pressure sensors are required to collect system pressure data, the use of pressure sensors will undoubtedly increase the hardware cost of the base station air conditioner, and the installation of pressure sensors in the air conditioner pipeline will also increase the complexity of product design and assembly
