Problems solved by technology

Although these devices have recovered and utilized the waste heat of waste hot water to varying degrees, they are still not sufficient. In addition, in many cases, only relying on the use of heat pumps to recover the waste heat of waste hot water to heat supplementary water and keep hot water is not enough. not enough

Abstract

The invention relates to a hot wastewater waste-heat recovery type heat pump hot-water system by utilizing waste heat of domestic and industrial hot wastewater, which comprises a wastewater recycle pool, a hot water tank, a filter, a water source circulating water pump, a water source heat pump, a make-up water pipe, a heat preservation water tank, a hybrid resource heat pump, a circulating water pump, a make-up water resource heat pump, a wastewater heat exchanger, and a hot wastewater circulating water pump, wherein three groups of modular units, namely the water source heat pump, the make-up water resource heat pump and the hybrid resource heat pump can be cooperated to run, also can be used independently and have flexible combination and convenient operation. An outdoor heat exchanger and a second heat exchanger of the hybrid resource heat pump can utilize thermal energy of air and the hot wastewater respectively; and when the defrosting is performed, the outdoor heat exchanger is taken as a condenser, and the second heat exchanger utilizes the hot wastewater as a heat source and is taken as an evaporator, the system has good defrosting effect and does not influence hot water temperature. The heat pump hot-water system utilizes the waste heat in a step way, fully recovers the waste heat, and has energy conservation and consumption reduction after the hot wastewater is collected.

Description

technical field [0001] The invention relates to the field of heat pump hot water system and energy-saving technology, in particular to a composite source heat pump hot water system that can utilize waste heat from living and production waste water. Background technique [0002] At present, most of the bathing centers, hotels, guesthouses, factories, and schools in most cities and towns in my country use fuel boilers or electric boilers for heating, except for a few that use urban heating networks for heating. Fuel boiler heating devices rely on direct combustion of coal, oil or natural gas to obtain heat, which not only has low efficiency and causes energy waste, but also produces carbon dioxide greenhouse gas and smoke that seriously pollute the environment; electric boilers directly convert high-grade electrical energy into heat energy, Effective energy utilization is very low. With the global energy crisis and people's increasing awareness of energy conservation and envi...
