Abstract

The invention relates to an energy-saving control method of a frequency-fixed heat pump water heater floor radiant heating system. The method is characterized by including the energy-saving control steps of calculating the functional expression between the water supply calculation temperature Tgj of a floor and the outdoor environment temperature Tw through a control system according to the performance of a frequency-fixed heat pump water heater and thermal load characteristics of a heating room, establishing the functional expression between the room calculation air temperature Tnj based on the human body thermal comfort degree and the outdoor environment temperature Tw through the control system, and making the water supply calculation temperature Tgj+ / -1 DEG C serve as the start and stop control temperature of the frequency-fixed heat pump water heater through the control system. The method has the advantages that the energy efficiency of the heat pump water heater is high, and energy-saving running and the higher human body comfort degree are achieved.

Description

technical field [0001] The invention relates to an energy-saving control method for a floor radiation heating system of a fixed-frequency heat pump water heater. Background technique [0002] As a high-efficiency and energy-saving hot water product, heat pump water heater is more and more applied to floor radiant heating. At present, the design water supply / return water temperature of the heat pump water heater floor heating system is generally 45°C / 35°C, and the room temperature is mostly realized by controlling the start and stop of the heat pump water heater by the floor surface temperature or the room air temperature. Because the energy efficiency of the heat pump water heater decreases with the increase of the water supply temperature, and the outdoor ambient temperature changes greatly within a heating cycle, and the outdoor ambient temperature also varies greatly within a day, so the heating load varies in different time periods. larger. When the outdoor ambient te...
