Description
Technical field
The utility model relates to technical field of heat pumps, and in particular to a kind of cold and hot pump assembly of evaporation.
Background technique
In three kinds of types of cooling of air-conditioning, identical cooling capacity is obtained, using unit (the evaporation cold for evaporating cold mode
Group) compared with 30% or more the unit of air cooling (air-cooled unit includes multi-joint unit) energy conservation, relatively use the unit (water of water cooling mode
Cold group) 15% or more energy conservation, evaporate cooling performance highest.
Wherein, the process of air-conditioner set thermodynamic cycle is the mistake that cooling capacity, heat shift between evaporator and condenser
Journey, the inverse cyclic process of refrigeration are to heat, and evaporating cold refrigeration unit only realizes refrigeration, cannot achieve heat pump functional.
Traditional multi-connected heat pump unit realizes refrigeration, heating, the heat pump unit efficiency when outdoor environment temperature is lower than -5 DEG C
It substantially reduces, when spending lower than -12, unit efficiency is almost " 0 ".
And multi-joint unit (heat pump), evaporation cold group need the thermal energy row compressor work generation in refrigerating operaton
It is put into outdoor environment, these amount of heat being discharged (thermal energy) are consumption electric energy productions, therefore there are you to waste now
As.
Currently, spray vapour increasing culvert technology improves the heating efficiency of air-cooled (multi-joint) heat pump at low ambient temperatures and makes it -25
The especially low raising 20%-50% of heating capacity at -15 DEG C is efficiently heated under DEG C environment, multi-connected heat pump is made to enter " Qiang Lengre "
Epoch.But increases culvert technology just because of spray vapour to use, the preceding supercooling that throttles on the one hand is carried out to main circulation loop refrigerant, increase enthalpy
Difference；On the other hand, to swollen by electronics in subsidiary loop (this road refrigerant will directly participate in compressing by importing in the middle part of compressor)
Low+warm refrigerant of low pressure after swollen valve decompression carries out preheating appropriate, to reach suitable middle pressure, is supplied to compressor progress
Second-compressed, and lead to compressor often and will appear high temperature protection and " crash " phenomenon occurs, or even cause compressor " burning ",
Therefore solution is mostly: 1, closing secondary circuit and reduce secondary medium temperature opposing steam flow amount reduction compression chamber temperature to the row of reduction
Temperature degree；2, increasing bypass H and increasing liquid measure reduces compressor vapour chamber temperature+to reducing delivery temperature；3, outdoor environment temperature
Turning off secondary circuit reduction culvert difference when degree is higher than safe operating temperature when (25 DEG C -29 DEG C) reduces back liquid temperature.Though aforesaid way
It is attained by the purpose for reducing compressor exhaust temperature but all unit is caused to reduce efficiency.
In field of air conditioning recuperation of heat two ways nothing more than: i.e. non-total heat recovery and total heat recovery.Two kinds of ways of recycling are each
There is advantage but all defective:
(1) non-total heat recovery be compressor spray vapor outlet install additional hot-water recoverer, series connection with evaporator, condenser it
Between, in operation of air conditioner, hot water circuit pump startup can absorb the thermal energy production hot water of compressor work generation, without carrying out work
Non- total heat recovery hot water can be realized in the conversion of operation mode, and set structure is simple, pipe fitting is few, control system is single therefore unit
Operation stability is stronger；But its disadvantage is to absorb one due to coming from water tank cold water in heat regenerator when operating normally when unit
Some refrigerant heat and broken the ring original heat exchange balance of unit cause Indoor Temperature to influence the using effect of indoor units
There is larger fluctuation in degree, and recycling hot water amount and temperature are unstable, it is therefore desirable to configure hot water ancillary heating equipment, cause energy
The secondary waste in source.
(2) total heat recovery be by way of multiple valve member combination collocations, special circuit design make heat regenerator and steam
Hair device, condenser realize the conversion of the multiple functions such as independent cooling supply, individual heating, separate hot water in parallel, are meeting
100% total heat recovery that hot water can be achieved under the premise of cooling supply, without assisting hot water heating apparatus unit comprehensive effectiveness high.But
Its disadvantage is that component is more, pipeline complexity, control system are cumbersome, and unit power and energy frequency height leads to that set steady is poor, failure
Rate is high, and in the non-oepration at full load of compressor, the heat of compressor cannot be recycled, and reduce unit overall efficiency.
Currently, multi-joint unit accounting 70% or so in entire air-conditioning market share, therefore be also major power consumer, because
The energy conservation of this multi-connected machine has huge meaning；Secondly, 50% or more of the unit accounting air-conditioning of refrigerating function, and evaporative condenser
It to be popularized as most energy-efficient refrigeration modes urgent need.
From above-mentioned analysis it is found that how to develop a kind of with industry highest heating efficiency, refrigerating efficiency, the recyclable benefit of thermal energy
With the powerful and stable, heat pump unit that has a wide range of application, it has also become those skilled in the art need the technology solved
Problem.
