Problems solved by technology
[0004] If the compressor is operated with low power consumption, it still needs to have a heat source and a cold source, otherwise the evaporation will be insufficient, and the compressor will suck in the refrigerant liquid, which will cause liquid shock and damage the compressor. Insufficient condensation will also cause the system pressure to fail to maintain balance and automatically Protect

An instant heating type heat pump water heater capable of recycling shower waste heat is characterized by comprising a compressor, a main water tank, a secondary water tank, a sprinkler, a waste heat recycling device, an evaporation heat exchanger, a throttle valve, a constant-temperature water mixing valve, a pump, a three-way valve, a temperature sensor and a water flow induction switch. An operating method of the heat pump water heater includes the steps of system pre-heating, system standby, system normal operation and system temporary stop. The instant heating type heat pump water heater and the operating method of the instant heating type heat pump water heater have the advantages that the heat pump water heater is not affected by the environment and weather, can stably operate all the year round, approaches to instant heating when being started, recycles waste heat in real time, and is high in utilization rate; cold start of the heat pump water heater and the low-power-consumption standby of the compressor are realized, the work conditions of instant heating when the heat pump water heater is started are created, operations safety of system core parts is guaranteed with low cost, and the service life is prolonged.
Description
【Technical field】 [0001] The invention relates to a heat pump water heater, in particular to a quick-heating type heat pump water heater for recovering shower waste heat and an operation method thereof, belonging to the technical field of energy-saving equipment. 【Background technique】 [0002] With the continuous progress of heat pump technology, many patent applications at home and abroad have proposed to recycle the waste heat of shower waste water as a low-temperature heat source for heat pump water heaters, thus forming a new type of heat pump water heater. In China Invention Patent Application No. 201210077810.8, the applicant proposed a fast-heating heat pump water heater that recovers shower waste heat, and pointed out that the online instant recovery of shower waste water used as the heat source of the heat pump water heater will face no heat source startup and compressor in practical applications. The problem of frequent start and stop. Among them, the problem of ...
