Integrated unpressurized water source hot-water supply system

Abstract

The invention discloses an integrated unpressurized water source hot-water supply system. The system includes a waste-hot-water tank, a main machine, a hot-water storage tank, a tap water inlet pipe,a manual water supplement pipe, a manual water supplement valve, an overflow opening, an overflow water pipe, a sewage discharging pipe, a sewage discharging valve, a wastewater source circulation pipe, a preheated-water inlet pipe, a water supplement solenoid valve, a hot-water conveying pipe, a hot-water supply pipe, a waste-hot-water recovery pipe, a sand remover, an oil separator and a filter;and the overflow opening is arranged in the waste-hot-water tank. The system provided by the invention can recover low heat quantity of waste hot water and transfer the low heat quantity to tap waterto solve the problems of a low heat recovery rate, waste of heat energy and the like in a traditional hot-water supply system.

Description

technical field [0001] The invention relates to the field of hot water engineering, in particular to an integrated non-pressurized water source hot water supply system. Background technique [0002] With the improvement of people's living standards, people's requirements for water are getting higher and higher, and the use of hot water has become a daily need, so people hope to build a building that can meet individual or collective hot water needs, and cooperate within a time period Activities of energy-saving hot water projects. [0003] Early hot water projects mainly used coal, oil, gas, and electric auxiliary as raw materials for boiler heating. It has the advantages of fast heating and large water output, but it uses oil and gas as fuel, and its energy consumption is very high. The fuel transportation pipeline must pass the fire safety inspection and acceptance. There are unsafe factors in the use process, and the surrounding air will be seriously polluted during the ...
