Control method of intelligent comfortable cooling and heating household air conditioning system

Abstract

The invention relates to the technical field of indoor heating and ventilation, in particular to a control method of an intelligent comfortable cooling and heating household air conditioning system. The control method comprises the following steps: in a heating mode, valves of a capillary network and a ground temperature adjusting pipe network are controlled to be opened through a valve controller for heating; in a refrigerating mode, the valves of the capillary network and the ground temperature adjusting pipe network are controlled to be opened, meanwhile, water supply at the set temperature is controlled and provided through a water mixing temperature adjusting controller for cooling; when the control result of the capillary network and the ground temperature adjusting pipe network cannot meet the set requirement, a fan coil is opened in a linkage mode; and when the control result of the capillary network and the ground temperature adjusting pipe network can meet the set requirement, the temperature is controlled by controlling a proportional integral valve through the water mixing temperature adjusting controller in the heating mode, and the temperature is controlled by opening and closing the valves of the capillary network and the ground temperature adjusting pipe network in the refrigerating mode. Radiation temperature adjustment is mainly adopted, the temperature can be rapidly adjusted, the blowing feeling is reduced, and the comfort degree is improved.

technical field [0001] The invention relates to the technical field of indoor heating and ventilation, in particular to a control method for an intelligent, comfortable and energy-warming household air-conditioning system. Background technique [0002] HVAC plays an important role in the smart home industry. It is a just-needed system in the home environment. It organically combines the smart home system with the HVAC system, and the five constant systems (constant temperature, constant humidity, constant oxygen, constant clean, constant Static) is an important part of the HVAC system. In the current HVAC system, the existence of single multi-connected air conditioners is mainly in the form of air convection.

[0002] HVAC plays an important role in the smart home industry. It is a just-needed system in the home environment. It organically combines the smart home system with the HVAC system, and the five constant systems (constant temperature, constant humidity, constant oxygen, constant clean, constant Static) is an important part of the HVAC system. In the current HVAC system, the existence of single multi-connected air conditioners is mainly in the form of air convection. Control the temperature, only dehumidify when the fan plate is cooling, and cannot effectively control the humidity

This control method cannot avoid the problem of condensation during cooling, and condensation will cause mold in the pipes, corrode furniture, and damage the health and property of users; the heating efficiency in winter is low and the use cost is high

[0003] For example, underfloor heating alone can only heat, and the heating can only be turned on and off, the heating temperature is uncontrollable, and the heating temperature changes significantly; it cannot be cooled, and forced cooling cannot solve the cooling condensation problem

The fresh air system is often operated independently, and most of the fresh air fans only have to be turned on and off, and need to run continuously for 24 hours, which cannot be intelligently controlled; during the operation of the air conditioning system, the fresh air will cause a certain degree of energy waste to the air conditioning system

[0004] That is to say, in the prior art, each system in HVAC exists independently of each other and operates independently, which is complicated for users to use.

Moreover, most systems can only do rough switching, and cannot realize the cooperation between systems and the optimal operation mode of the system
