Abstract

The invention discloses a wasteheat recovery system of a circulating hot water unit of a heat pump. The system comprises a first condenser, a compressor, a second condenser, a throttling unit, a circulating water tank and a wasteheat recoverer, wherein the first condenser, the second condenser and the wasteheat recoverer are provided with four ports, separately, the four ports are separately a first upper port, a first lower port, a second upper port and a second lower port, the first upper ports and the first lower ports of the first condenser, the second condenser and the wasteheat recoverercommunicate correspondingly, and the second upper ports and the second lower ports of the first condenser, the second condenser and the wasteheat recoverer communicate correspondingly. According to the system, wasteheat of a condensing working medium is recovered by means of a second condenser pipeline, so that the condensing temperature is reduced and the evaporating temperature is increased. The condensing temperature is further reduced by means of the wasteheat recoverer, so that the back temperature of the compressor is increased, and the heating capacity and the energy efficiency ratio of a heat pump system are improved. Meanwhile, it is also beneficial for defrosting the second condenser in a frosting working condition.

Description

technical field [0001] The invention relates to the technical field of heat pump equipment, in particular to a waste heat recovery system of a circulating heat pump hot water unit. Background technique [0002] Conventional circulating heat pump water heaters (including circulating heat pump water heaters) use water-cooled heat exchangers to exchange heat between circulating water and condensers. The high-temperature and high-pressure working medium gas compressed by the compressor passes through the condenser and circulates water for heat exchange, and then the working medium cools down to achieve condensation. At the same time, the circulating water will bring the heat in the condenser to the water tank to heat the water in the water tank. When the water temperature in the water tank is higher, the circulating water temperature will be correspondingly higher. The higher the temperature of the circulating water, the higher the condensation temperature of the heat pump circ...
