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
Air Source Heat Pump Air Conditioning provide house heating and hot
water,wherever need hot water, energy saving and more economical,
not feel dry,it is widely use in hospital,sauna,factory,commercial
centre,slaughter, swimming pools, spas, etc
