Solar Heat Pump Household Central Hot Water System

Abstract

The invention discloses a solar heat pump household type central hot water system. The solar heat pump household type central hot water system comprises a solar hot water loop, an air source heat pumphot water loop and a solar-air source coupling hot water loop, wherein the loops are connected; due to the fact that the system is provided with a solar heat collection plate and an evaporator, the solar and air source coupling manner is adopted to heat sea water, a hot source for generating low-pressure water steam achieves full-weather work, fresh water is self-produced, the self-produced freshwater directly serves as domestic hot water, the temperature is controllable, and the beneficial effects of being energy-saving and reliable in running are achieved. High-quality central hot water can be stably supplied to household buildings, and the resident life condition of the fresh water resource shortage area or site like an island can be effectively improved. Due to the fact that the system comprises multiple distillation chambers, the multi-effect distillation manner is selected in sea water desalination, the higher water production rate is achieved, the energy saving effect is further improved, according to the exterior environment condition, different loops are selected for running, and the system comprises the solar hot water loop, the air source heat pump hot water loop and the solar-air source coupling hot water loop.

Description

technical field [0001] The invention relates to an energy-saving and water-saving equipment, which uses solar energy and air energy to perform multi-effect evaporation and desalination of seawater, and the fresh water produced is directly used as domestic hot water, and the temperature of the hot water can be adjusted; specifically, by using seawater desalination technology Self-produced fresh water with controllable temperature is a solar heat pump household central hot water system to meet the hot water demand of fresh water resource-poor areas, including islands or coastal residents. Background technique [0002] With the increasing scarcity of fresh water resources, the vigorous promotion of island development and the rapid development of the marine engineering equipment industry, the demand for fresh water in coastal cities, islands and offshore drilling platforms is increasing, and the effective and sufficient supply of hot water for personnel is difficult. phenomenon ...
