Quick heating type heat pump water heater for recovering shower waste heat

Abstract

A quick heating type heat pump water heater for recovering shower waste heat is composed of a condenser, an evaporator, a throttling device, a compressor, a heat regenerator, a preheater, a primary water tank, an auxiliary water tank, a water mixing controller, a spraying device and a valve. The heat regenerator and the evaporator are installed under the feet of a shower person, the spraying device is arranged above the head and communicated with the water mixing controller, the preheater is arranged in the auxiliary water tank, the condenser is arranged in the primary water tank, the water outlet end of the auxiliary water tank is connected with an inlet of the water mixing controller, and the water inlet end of the auxiliary water tank is connected with a water outlet pipe of the primary water tank. One end of the valve is connected with tap water, the other end of the valve is respectively connected with a water inlet pipe of the primary water tank and a water inlet pipe of the heat regenerator, and the water outlet end of the heat regenerator is communicated with the water mixing controller. The condenser, the throttling device, the evaporator and the compressor form a closed loop, an outlet of the condenser is connected with an inlet of the throttling device, an outlet of the throttling device is connected with an inlet of the evaporator, an outlet of the evaporator is connected with an inlet of the compressor, and an outlet of the compressor is connected with an inlet of the condenser.

Description

technical field [0001] The invention relates to a heat pump water heater, in particular to a fast-heating type heat pump water heater which recovers waste heat from a shower. It belongs to the technical field of energy-saving equipment. Background technique [0002] With the continuous progress of heat pump technology, air source heat pump water heaters have been widely used abroad, and their domestic applications have also made great progress. However, the working characteristics of the air source heat pump water heater are greatly affected by the ambient temperature. In summer, the compressor suction pressure is likely to be too high due to the high ambient temperature. In winter, the evaporator is likely to frost due to the low ambient temperature. [0003] Shower waste water contains a large amount of waste heat. Using it as a heat source for heat pump water heaters can significantly improve the stability and heating performance of the system, so it has attracted much a...
