Comprehensive afterheat heating system for domestic hot water and swimming pool water

Abstract

The invention discloses a comprehensive afterheat heating system for domestic hot water and swimming pool water and relates to the technical field of afterheat utilization of hotels. The system is composed of a washhouse indoor heat-absorbing device, a washhouse room-temperature converting hot water and swimming pool water heating device, a heat-insulating water tank for washhouse condensate water, waste water and boiler room condensate water, a heat pump heat-accumulating device, a central air-conditioner heat recycling device and a central air-conditioning system. The system provided by the invention integrates various heat, such as, high-temperature air heat generated by steam of a washhouse ironing machine, steam condensate heat of the ironing machine, washing waste water heat discharged from washhouse, boiler condensate heat of the boiler room, summer heat recovery of the central air-conditioner, and the like, and applies to the heat source for heating the hotel swimming pool water and the domestic hot water; an afterheat mode thoroughly replaces the running mode of utilizing steam to heat the swimming pool water and the domestic hot water in the prior art; the running cost is reduced; the yield returns are increased; the operating cost of the hotels is reduced; the market competitiveness is increased.

Description

technical field [0001] The invention relates to the technical field of hotel waste heat utilization, in particular to a comprehensive heating system for domestic hot water and swimming pool waste heat. Background technique [0002] At present, most hotels and hotels are equipped with central air-conditioning systems with chiller cooling mode to solve the problem of cooling in summer; in addition, they are equipped with gas-fired boiler steam heating systems, which use steam to meet the heating needs of hotels and hotels in winter, supply domestic hot water throughout the year, and provide laundry for laundry. Ironing machines provide ironing steam, heating of swimming pool water and kitchen steam as needed. Although some hotels and hotels have adopted heat recovery measures in the central air-conditioning system, and some hotels and hotels have carried out energy-saving utilization of steam condensed water, but they all belong to the local small-scale single-function waste h...

AI Technical Summary

Problems solved by technology

There are also ironing machines in the boiler room and laundry room. A large amount of steam condensate is discharged every day, especially the temperature of the condensate in the boiler room is about 120-130°C. Because the water temperature is too high, it must be discharged with tap water after cooling down. , not only the high-temperature condensed water is discharged in vain, but also tap water resources are wasted, which is undoubtedly a waste of resources

[0003] Based on the above description, a new comprehensive heating system for domestic hot water and swimming pool waste heat is urgently needed to solve the problems of low waste heat utilization rate, high operating cost and waste of resources in the existing technology
