Problems solved by technology

[0004] As mentioned above, the use of electric compressors in vehicles can solve the problem that the existing compressors are susceptible to engine speed and affect the cooling effect of the room. However, the electric compressors turn on and off according to the temperature set by the air conditioning system, and there will be Excessive starting current and power consumption cause the problem of the burd

Embodiment Construction

[0046] For a preferred embodiment of the present invention, please refer to figure 1 , 2 As shown, they are the basic architectures of the air-conditioning system with only air conditioning and the cold / warm air-conditioning system with both air-conditioning and heating, such as figure 1 As shown, the simple air-conditioning system includes a compressor 11, a condenser 12, an expansion valve 13, and an evaporator 14 connected in series. A condenser fan 15 is arranged outside the condenser 12, and a condenser fan 15 is arranged outside the evaporator 13. There is a blower 16, the refrigerant in the air conditioning system is driven by the compressor 11 to pass through the condenser 12, the expansion valve 13 and the evaporator 14 in sequence, and then returns to the compressor 11, and the heat of the refrigerant passing through the condenser 12 is transferred by the condenser fan 15 It is discharged to the outside, and then the indoor heat is absorbed by the refrigerant passin...

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...
