Title: Design of a Control System of a New-type Heat Pump Water Heater
Abstract: The heat pump water heater is a new-type heating equipment.It can substitute for the boiler as a heat equipment and water heating device.After heat absorption through the temperature difference of the refrigerant and heat generation through compressor,the heat pump water heater changes heat with water.In this way,the thermal efficiency is improved and the energy is utilized fully.But the water heater of the heat pump needs a good and reliable control system.It can be controlled by touch screen and PLC.Based on the knowledge of water heater operation principle of the heat pump,the touch-sensitive screen interface and PLC control procedure are designed based on the control request of the system and hardware environment.
