Description
Technical field
The utility model relates to a kind of cooling heating installation.
Background technology
China has become small-sized wind source heat pump manufacturer the biggest in the world and maximum use state, and safe, reliable, the stable feature of wind source heat pump is by everybody is familiar with, accepts.But wind source heat pump is influenced by ambient temperature very large, the north in the winter time outdoor temperature for a long time lower than-5 DEG C, summer for a long time higher than 35 DEG C, now the Energy Efficiency Ratio of wind source heat pump will be lower, people adopt large-scale water source heat pump system to solve changes in temperature problem in recent years, but the most areas of China is due to the restriction of geological conditions, underground water storage is limited, and the groundwater recharge difficulty extracting, the application of large-scale water resource heat pump is very restricted, and therefore large-scale water source heat pump system is not the reasonable plan of dealing with problems.And adopting traditional wind source heat pump that heat or cold are provided, the heating of application fan coil or air-line system, if do not adopt the electric additional heat must blowing cold air in cold season, cannot meet heating needs, adopts the additional hot network load of electricity cannot all meet again.Moreover traditional wind source heat pump operating cost is too high, consumer cannot accept at all; And in the time of application fan coil or air-line system cooling, again because system evaporating temperature is low, operational energy efficiency is very not energy-conservation during than low cooling.
In order to address the above problem, in the patents such as ZL200820071027.X, ZL201010502398.0, ZL201220275353.9, ZL201220275358.1 and ZL 2,008 2 0071026.5, conduct in-depth research, obtained corresponding system achievement, cooling heating can realize relative energy-saving run.But in patent in the past, just the indoor set system of heat pump assembly is changed to: the two ends at indoor fan coil pipe arrange threeway, and electric T-shaped valve is set or magnetic valve is installed, a path leads to indoor fan coil pipe, another path leads to the coil pipe being embedded in wallboard or ceiling or floor or hanging board, when heating, compressed vapour directly enters in the coil pipe being embedded in wallboard or ceiling or floor or hanging board, compressed steam, be embedded in the heat source body that coil pipe in wallboard or ceiling or floor or hanging board forms indoor radiant heat transfer together with wallboard or ceiling or hanging board, when cooling, compressed media enters fan coil.Under driven compressor, continue circulation by compressed steam and maintain stable cold, the warm Power supply that carries out, meet the demand of indoor cooling heating.When heating, adopt compressed steam, be embedded in the heat source body transferring heat that coil pipe in wallboard or ceiling or floor or hanging board forms indoor radiant heat transfer together with wallboard or ceiling or hanging board, when heating, the condensation temperature of heat pump reduces more than 10 DEG C, equipment input power is little, Energy Efficiency Ratio is high, and (the Gao Shike of COP of heating operation reaches more than 6.3, heating season comprehensive energy efficiency ratio can reach more than 2.8), noise is low, the psychological need of flooring radiation heat supply and human body adapts.This is a kind of very advanced method, has: energy-saving and environmental protection, can realize the advantages such as household metering.Do not make and change for the outdoor machine system of wind source heat pump.
Although can cooling in above-mentioned technology, heating, because modern architecture is function and the interdisciplinary science being melted into a whole attractive in appearance, for building designers attractive in appearance by off-premises station embed outer within the walls, cause the circulation of off-premises station ambient wind not smooth.Even if expose to the off-premises station of body of wall, owing to adopting the axial flow blower of low static pressure, air-out is sent not go out and is spinned around main frame, causes that main frame environment temperature is too high in summer, winter is too low.Show according to long-time test, off-premises station embeds Outer Wall portion and uses under the bad working environments of rainproof grid, and off-premises station ambient temperature in summer (return air temperature) is than exceeding more than 17 DEG C when ground temperature, and extreme weather situation reaches 57 DEG C ~ 58 DEG C for a long time.Off-premises station ambient temperature in summer in winter (return air temperature) is than reducing more than 9 DEG C when ground temperature, and extreme weather situation reaches-22 DEG C ~-23 DEG C for a long time; Even outside is not used rainproof grid in damascene structures, the building enclosure that only adopts ornamental weather proof to blow off, off-premises station ambient temperature in summer (return air temperature) is than exceeding more than 11 DEG C when ground temperature, and extreme weather situation reaches 51 DEG C ~ 52 DEG C for a long time.Off-premises station ambient temperature in summer in winter (return air temperature) is than reducing more than 6 DEG C when ground temperature, and extreme weather situation reaches-19 DEG C ~-20 DEG C for a long time; Even if do not adopt embedded design, directly outer being hung on exterior wall in calm, off-premises station ambient temperature in summer (return air temperature) is than exceeding more than 7 DEG C when ground temperature, extreme weather situation reach for a long time 47 DEG C ~ more than 48 DEG C.Off-premises station ambient temperature in summer in winter (return air temperature) is than reducing more than 4 DEG C when ground temperature, extreme weather situation reach for a long time-17 DEG C ~ below-18 DEG C.Severe exacerbation the working environment of wind regime main frame.The operating efficiency of main frame reduces greatly than the operating efficiency under actual weather operating mode, cannot energy-saving run.The explanation of above-mentioned situation, the space that above-mentioned heat supply (warm up), cooling form, confession (heat) warmed up, cooling equipment still exists further perfect, raising.
