Description

The liquid circulated water-loop heat pump equipment taking energy
Technical field
The present invention relates to a kind of cooling heat and heat water supplying device for new wind.
Background technology
Wind source heat pump is influenced by ambient temperature the biggest, north outdoor temperature in the winter time is for a long time less than-5 DEG C, have summer long-time higher than 35 DEG C, now the Energy Efficiency Ratio of wind source heat pump will be relatively low, people use large-scale water source heat pump system to solve changes in temperature problem in recent years, but the most area of China is due to the restriction of geological conditions, subsoil water storage is limited, and the groundwater recharge difficulty extracted, the application of larger water source heat pump is very restricted, particularly large-size air conditioning service system circulating load is big, circulating consumption is high, can not accurate household metering, cannot be carried out toll administration, in practicality, undue use causes waste, therefore large-scale water source heat pump system is not the reasonable plan of solution problem.And use traditional wind source heat pump to provide heat or cold, application fan coil or air-line system heating, if not using the electric additional heat must blowing cold air in cold season, it is impossible to meet heating needs, use the additional hot network load of electricity cannot all meet again.Moreover, traditional wind source heat pump operating cost is the highest, and consumer cannot accept at all;And when applying fan coil or air-line system cooling, low because of system evaporating temperature again, operational energy efficiency is more energy-conservation than during low cooling.
In order to solve the problems referred to above, in the patents such as ZL 2,008 2 0071027.X, ZL201010502398.0, ZL201220275353.9, ZL201220275358.1 and ZL 2,008 2 0071026.5, conduct in-depth research, achieving corresponding system achievement, cooling heating is capable of relative energy-saving run.But simply the indoor set system of heat pump assembly is changed in conventional patent: at the two ends of indoor fan coil pipe, threeway is set, and electric T-shaped valve is set or electromagnetic valve is installed, one path leads to indoor fan coil pipe, another path is towards being embedded in the coil pipe in wallboard or ceiling or floor or hanging board, in during heating, compressed vapour is directly entered the coil pipe being embedded in wallboard or ceiling or floor or hanging board, compressed steam, the coil pipe being embedded in wallboard or ceiling or floor or hanging board forms the heat source body of indoor radiant heat transfer together with wallboard or ceiling or hanging board;During cooling, compressed media enters fan coil.Maintain stable cold, the warm energy that carries out to supply by compressed steam persistent loop under driven compressor, meet the demand of indoor cooling heating.The coil pipe use compressed steam during heating, being embedded in wallboard or ceiling or floor or hanging board forms the heat source body transmission heat of indoor radiant heat transfer together with wallboard or ceiling or hanging board, during heating, the condensation temperature of heat pump reduces by more than 10 DEG C, equipment input power is little, Energy Efficiency Ratio is high (can reach more than 6.3 when the COP of heating operation is the highest, heating season comprehensive energy efficiency ratio can reach more than 2.8), noise low, flooring radiation heat supply adapts with the psychological need of human body.This is a kind of highly advanced method, have: energy-saving and environmental protection, the advantages such as household metering can be realized, this invention is the highest owing to greatly reducing the condensation temperature Energy Efficiency Ratio that therefore heats, and its heat pump utilize energy be from wind extract, temperature is relatively low in the winter time needs again defrosting, and systematic energy efficiency ratio declines the biggest;The patented technology cooling simultaneously announced does not has feature, uses fan coil transmission cold during cooling, and system conversion and control valve easily leaks, and after increasing wind dish, system cost increases, and causes unnecessary waste of material simultaneously.
Although can cooling, heating in above-mentioned technology, but system cost is high, control complexity, and pipe laying fluorine system and wind dish fluorine system are changed by electronic valve or electric T-shaped valve in floor, sealing is poor, easily cause another one system after long-play and lack fluorine or oil starvation, reduce system reliability of operation.When cooling, there is no difference with tradition wind regime air-conditioner.Particularly it is restricted due to outdoor temperature its popularization and application too low in north cold area, even if use Energy Efficiency Ratio also will not be the highest.
Above-mentioned situation illustrates, above-mentioned heat supply (warm up), cooling form, warm up for (hot), cooling equipment still suffers from the most perfect, the space of raising.
Summary of the invention
