Embodiment

[0037] Embodiment: An energy-saving control method for an intelligent frequency conversion central air conditioner

[0038] See attached image 3 , the central air conditioner includes a cooling and heating system and a control system; wherein the cooling and heating system includes a condenser, an electronic expansion valve, an evaporator, and a compressor connected in sequence by a refrigerant delivery pipe. Wherein, the condenser and the evaporator independently include a plurality of fins, and the plurality of fins are arranged side by side; and a heat pipe, and the heat pipe is arranged in the plurality of fins. The heat conduction pipe includes a heat conduction pipe body and a heat conduction pipe thread, the heat conduction pipe body defines a refrigerant passage, and the heat conduction pipe thread is formed on the inner wall of the heat conduction pipe body. It also includes a four-way valve for switching the direction of the refrigerant in the cooling state and the...

Abstract

The invention relates to an intelligent variable frequency central air-conditioning energy-saving control method. A first temperature sensor detects the indoor environment temperature in real time, meanwhile, a second temperature sensor detects the outdoor environment temperature in real time, and the temperatures are sent to a judgment module; an electronic expansion valve sends the valve openingdegree value under the environment temperature to the judgment module; the judgment module compares the indoor environment temperature with the outdoor environment temperature; if the outdoor environment temperature is higher than or equal to 175% of the indoor environment temperature, the fourth step is executed, or the fifth step is executed; a control module sends a first signal to a driving circuit, so that the driving circuit drives a driving motor to rotate, the opening degree of the electronic expansion valve is adjusted, and the indoor environment is adjusted to the temperature in theS1; and the control module sends a second signal to the driving circuit, the driving circuit drives the driving motor to rotate, the opening degree of the electronic expansion valve is adjusted, andthe indoor environment is adjusted to the temperature in the S2.

Description

technical field [0001] The invention belongs to the field of air conditioners, in particular to a hot and cold air conditioner, in particular to an energy-saving control method for an intelligent frequency conversion central air conditioner. Background technique [0002] The central air-conditioning system is composed of one or more cold and heat source systems and multiple air-conditioning systems. This system is different from traditional refrigerant air-conditioning systems (such as single-body units, VRV) to centrally process air to meet comfort requirements. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. [0003] Existing central air conditioners have a common disadvantage, namely high energy consumption an...
