Air-conditioning control system and air-conditioning control method

Abstract

The invention provides an air-conditioning control system and an air-conditioning control method. The air-conditioning control system comprises a heat pump unit, temperature controllers and a terminal signal transmission device. The heat pump unit is used for providing cold and hot water for meeting cooling / heating requirements of air-conditioned regions, and the water temperatures of the cold and hot water provided by the heat pump unit can be detected; the temperature controllers are used for controlling on and off of air-conditioning terminals and electric water valves according to the detected internal temperatures of controlled regions of the air-conditioning terminals, and strong-current signals for controlling the electric water valves can be outputted; the terminal signal transmission device is used for transmitting the strong-current signals outputted by the temperature controllers to the heat pump unit, and on and off of the heat pump unit can be controlled according to the detected water temperatures and the strong-current signals. The air-conditioning control system and the air-conditioning control method have the advantages that the problem that an existing unit unnecessarily runs due to the fact that on and off of the existing unit are only controlled according to air-conditioning water temperatures in the prior art can be solved, and effects of implementing linkage control on the heat pump unit and the temperature controllers and effectively reducing energy consumption can be realized without affecting the flexibility of engineering designs and model selection.

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...
