A method for making high-efficiency air conditioner and heat pump controller

Abstract

A method for making high-efficiency air-conditioning and heat pump controllers belongs to the energy-saving field. The automatic control function of the air-conditioning and heat pumps is set by the controller for controlling the ambient temperature, but the current control method does not control the factors of high efficiency and energy saving. And the present invention is: the temperature of the external environment liquid or gas of setting evaporator is t1, the temperature of the internal environment gas-liquid mixture of evaporator is T1, the temperature of gas-liquid mixture in the condenser is T2, the external environment liquid of condenser or The temperature of the gas is t2, then when the temperature of t1 is higher than the set temperature upper limit or the temperature of t2 is lower than the set lower limit and the value of t1-T1 or T2-t2 is less than 15° or less than 10° or less than 5° or When it is less than 2°, turn on the power of the compressor to start working through the controller, otherwise stop the compressor. This method can increase the efficiency ratio to more than 6 by increasing the heat exchange area of ​​the heat exchanger, increasing the heat transfer coefficient k of the heat exchanger, increasing the heat exchange time, and reducing the power of the compressor. The ratio can be increased to more than 50. The controller is an effective guarantee to realize the energy-saving operation of the compressor.

Description

technical field [0001] It relates to a method for making a high-efficiency air conditioner and a heat pump controller. Background technique [0002] In recent years, many efforts have been made to improve the efficiency ratio of refrigerators, air conditioners, and heat pumps, such as increasing the compression [0003] The mechanical performance of the machine can be reduced by frequency conversion to reduce the power loss caused by the frequent start of the compressor, and the heat exchanger (including the evaporator and [0004] Condenser) and the heat exchange efficiency of the surrounding environment have played a great role in improving the performance ratio of air conditioners and heat pumps. improving [0005] In terms of heat exchange efficiency of heat exchangers, according to the heat exchange formula: Q = kFΔt, the common method to increase the efficiency ratio of refrigerators, air conditioners, and heat pumps at this stage is to increase the heat exchange are...
