Central control device and control method for household composite air conditioning system

Abstract

A centralized control device of a household hybrid air-conditioning system and a control method thereof relate to the technical field of the control devices of air-conditioning systems which regulate indoor temperature and humidity by utilizing a direct digital controller. A first signal output end of a main control panel is connected with a signal input end of a water distributor and collector, an electric heating valve is arranged on the water distributor and collector, and a signal output end of the water distributor and collector is connected with the signal input end of a secondary side water pump; a second signal output end of the main control panel is connected with a first signal input end of a DDC, and the signal output end of the DDC is connected with a heat pump and the signal input end of a fresh air unit; a three-way valve of the fresh air unit and a plate type heat exchange valve are respectively connected with the direct digital controller. The invention realizes the simple operation, the function integration and the purpose of being capable of operating indoor temperature and humidity of various signal rooms.

Description

technical field [0001] The invention relates to the technical field of an air-conditioning system control device for adjusting indoor temperature and humidity by using a direct digital controller (Direct Digital Control, DDC for short). Background technique [0002] With the improvement of people's living standards, many families have air conditioners and other electrical appliances that adjust the indoor temperature, but these electrical appliances only work individually during use, and the temperature of each room is completed according to the set value, so it cannot Good coordination is used to adjust the temperature balance of the entire home, resulting in waste of resources. In addition, a single electrical appliance needs to be operated one by one when it is started and shut down, so that several remote controllers are needed, and the operation is cumbersome. Contents of the invention [0003] The object of the present invention is to provide a centralized control d...
