Air energy water heater and heat storage device thereof

Abstract

The invention relates to an air energy water heater and a heat storage device thereof, and belongs to the field of air energy water heaters. The water heater comprises an intelligent control device, acompressor and a phase-change heat storage pool connected with the compressor. When the intelligent control device detects that it belongs to off-peak electricity at present, the compressor is controlled to be started; the compressor heats a phase-change material through the heat exchanger and stores the heat in the phase-change heat storage pool; the phase-change heat storage pool is provided with a cold water inlet and a hot water outlet, and cold water entering the cold water inlet is heated to a preset temperature through a heat exchanger in the phase change heat storage pool and flows out of the hot water outlet. A water tank is replaced by the phase-change heat storage pool, and the advantages of small size, small heat dissipation area and easiness in heat preservation are achieved;the temperature of the hot water outlet of the phase-change heat storage pool is kept at a preset temperature, the purpose of stabilizing the outlet water temperature is achieved, and valley electricity is used through the intelligent control device. The three defects of a traditional air energy water heater are overcome, and the air energy water heater has the advantages of being small in size,low in power consumption for maintaining constant temperature and stable in water outlet temperature.

Description

technical field [0001] The invention belongs to the field of air energy water heaters, and in particular relates to an air energy water heater and a heat storage device thereof. Background technique [0002] Water heaters are essential equipment for every family, and people especially like instantaneous water heaters for washing and bathing. Water heaters are also undergoing continuous changes, from the earliest direct-exhaust gas water heaters, flue-type water heaters and balanced water heaters, to forced-exhaust water heaters (with a small exhaust fan installed, which is safer than non-forced exhaust). Then to wall-mounted electric water heaters, solar water heaters, until the air energy water heaters that have appeared in recent years. Since the air-energy water heater obtains hot water by moving the heat in the air, it can use less electric energy to obtain a much higher energy efficiency ratio than direct electric heating, so it is loved by the public.
