Abstract

The invention provides a method for intelligent type constant temperature control suitable for a cold / warm air conditioning system. The method mainly comprises the steps that according to indoor temperature, outdoor temperature, set temperature and sunlight intensity, a thermal load estimated value needing to be subtracted from or added to the value of the air conditioning system is calculated, required cold / warm room power corresponding to the thermal load estimated value is calculated as well, operation of the air conditioning system is adjusted according to the thermal load estimated value, so that the required cold / warm room power is met, the difference between actual cold / warm room power and the required cold / warm room power is then measured, operation of the air conditioning system is adjusted repeatedly, and the requirement for constant temperature control is met. Thus, the power use efficiency of the air conditioning system is improved and the problems that burdens caused by repeated starting operation of an existing air conditioning system are brought to a power system, and efficiency is poor are solved.

Description

technical field

[0001] The invention relates to a constant temperature control device for an air conditioning system, especially an intelligent constant temperature control device that can automatically maintain the temperature of the air conditioning system by using thermal load estimation and comparing the actual required cooling / heating power. Background technique

[0002] The existing air-conditioning system includes a compressor, a condenser, an expansion valve and an evaporator connected in series. The condenser is provided with a condenser fan, and the evaporator is provided with a blower. The sequence goes through the condenser, expansion valve and evaporator, and then returns to the compressor to complete the process of absorbing and discharging heat, so as to achieve the purpose of adjusting the indoor air temperature. The refrigerant in the evaporator absorbs the indoor heat, and then the condenser fan Discharge the heat of the refrigerant passing through the cond...
