Description of 10.9 kw heating and air conditioning domestic hot water(DHW) heat pumps:
A heat pump water heater control system based on the Internet of Things is adopted. The data acquisition unit is used to collect preheating information and indoor air temperature information, and the data processing unit is used to receive preheating information and air temperature information and process them to obtain preheating. Processing information and air temperature processing information, using the data analysis unit to receive and analyze the preheating information and air temperature processing information to obtain the analysis data, and send the analysis data to the control and adjustment unit, and use the control and adjustment unit according to the first preheating information And the second preheating information respectively control the operation of the heat pump water heater in the morning and evening until the heat pump water heater’s preheating temperature reaches the preheating standard value for heat preservation treatment; all aspects disclosed in the present invention are used to solve the problems in the existing solutions The problem of automatic preheating according to the user’s work and rest time, and the problem of poor control of the preheating effect of the heat pump water heater
Application of air source heat pumps
