Air conditioning control system and method

Abstract

The present invention provides an air-conditioning control system and method. The system includes: a heat pump unit, used to provide cold and hot water to meet the cooling / heating demand of the air-conditioning area, and to detect the water temperature of the cold and hot water provided by it; a thermostat for According to the detected temperature in the control area of ​​the air-conditioning terminal, control the opening and closing of the air-conditioning terminal and the electric water valve, and output a strong electric signal for controlling the electric water valve; the terminal signal transmission device is used to transmit the strong electric signal output by the thermostat The electrical signal is transmitted to the heat pump unit, wherein the heat pump unit controls the start and stop of the heat pump unit according to the detected water temperature and the strong electric signal. Through the present invention, it solves the problem that the unit in the related art only controls the start and stop of the unit according to the water temperature of the air conditioner, which causes the unit to be unnecessary. On the basis of not affecting the flexibility of engineering design and selection, it achieves the linkage control of heat pump unit and thermostat, effectively reducing energy consumption.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control system and method. Background technique [0002] As a form of air conditioning unit, the hot and cold water unit provides cooling / heating needs for users by connecting with the fan coil unit to supply cold and hot water. Compared with multi-connected units, a great feature is that the end of the indoor unit does not need to communicate with the unit, so the selection and installation are very flexible. However, the control objectives of the two are completely different. The unit starts and stops based on the water temperature, while the indoor fan coil unit uses the room temperature measured by the thermostat as the control basis. The two are completely independent and do not communicate with each other. The requirements have been met, but the water temperature has not yet dropped to the set value of the unit and it is still running, r...
