Phase change heat storage air source heat pump water heater control system and its control method

Abstract

Disclosed are a phase change heat storage air source heat pump hot water unit control system and a control method thereof. A microcontroller unit, a sensor unit, an analog quantity conditioning unit, a data acquisition unit, a display unit, a communication unit, a control unit and a driving unit are combined to form the control system by means of a modularized system structure. By means of the automatic and data fusion technology, the operation state of a hot water unit is monitored, and automatic adjustment is achieved according to actual temperature of a thermal insulation water tank, environment temperature and different working conditions of the hot water unit. By means of the phase change heat storage air source heat pump hot water unit control system and the control method thereof, the monitored parameters are comprehensive; the structure is simple; control is convenient; continuous, reliable and safe operation of the hot water unit is achieved.
