Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing:
[0023] As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the implementation mode of the phase change heat storage heat pump water heater with a type II phase change heat storage device (20): when located in the phase change heat storage device (20) When the value of the temperature sensor (9) at the temperature measuring point is lower than the set temperature a, the value of the set temperature a is slightly higher than the phase change temperature of the phase change heat storage material (15) adopted, at this time in the control In the evaporator (8), the temperature sensor (2) signal at the air inlet temperature measuring point of the evaporator (3) is compared with the set temperature value b, and the value of the set temperature b is determined according to the phase change heat storage heat pump water heater. When working at this ambient temperature, the heating...
