Hot water supply system special for bathing pool and capable of recycling heat energy

Abstract

A hot water supply system special for a bathing pool and capable of recycling heat energy comprises a hot water tank, a sewage source heat pump unit, a sewage pool, a sewage heat exchanger and a hot water variable frequency pump. Waste water in the bathing pool after a bath is collected in the sewage pool through a waste water drainage ditch. The sewage heat exchanger is arranged in the sewage pool. The temperature of a low-temperature secondary refrigerant is increased after heat of the waste water is absorbed by the low-temperature secondary refrigerant circulating in the sewage heat exchanger, and the heat is released to a refrigerant in the heat pump unit through an evaporator of the heat pump unit. The heat, containing heat energy generated by the heat pump unit due to electricity consumption in the running process, in the refrigerant is all transmitted into water for washing through a compressor and a condenser, and then high-temperature water for the bath is obtained and enters a hot water pool through a pipeline. The hot water in the hot water pool is sent into the bathing pool for the bath through the hot water variable frequency pump, and therefore recycling of the heat is realized. According to the hot water supply system special for the bathing pool and capable of recycling the heat energy, 80% of the heat of the hot water for the bath comes from recovery by a heat pump, and meanwhile, the waste water is discharged after the temperature of the waste water is lowered to about 5 DEG C so that thermal pollution is avoided. The hot water supply system special for the bathing pool and capable of recycling the heat energy is high in energy efficiency ratio, energy saving, environmental friendly and practical.

Description

technical field [0001] The invention relates to the technical field of renewable energy, in particular to a hot water supply system dedicated to thermal energy recycling for baths. Background technique [0002] At present, most of the heat sources used in the baths are coal-fired boilers. Among them, the coal-fired boilers in public baths need to operate continuously to supply a large amount of heat, and the problem of environmental pollution is relatively serious. There is a large amount of waste water from the shower in the bath, the general temperature is about 35°C, which contains a lot of heat energy. After the sewage is discharged, it will not only take away the heat energy in vain, but at the same time, the hot water exceeding 30°C will be discharged underground. cause heat pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency method for extracting heat from waste water and directly...
