Description
Technical field
This utility model relates to a kind of carbon dioxide air source heat pump.Particularly relate to a kind of carbon dioxide air source heat pump evaporation and send out fall enthalpy system.
Background technology
CO 2 cross-critical heat pump techniques, main by Trans-critical cycle compressor, expansion valve, air cooler, vaporizer forms, in Trans-critical cycle system, low-pressure section, the pressure of inspiration(Pi) of compressor is less than critical pressure, and evaporating temperature is also below critical temperature, the endothermic process of circulation is still carried out under undercritical conditions, and heat transfer process mainly relies on latent heat to complete.But the pressure at expulsion of compressor is higher than critical pressure, and at supercritical range, not having phase transformation, pressure and temperature is the most independent parameter, overcomes the restriction that subcritical cycle is affected by environment.So, CO2 Trans-critical cycle kind of refrigeration cycle has an advantage of continuously adjustable cold within the specific limits, affected by environment not quite.This technology is mainly used in indoor heating refrigerating field.
CO 2 cross-critical air source heat pump, mainly by Trans-critical cycle compressor, expansion valve, water cooler, air cooler forms, is a kind of air source heat pump utilizing CO 2 trans-critical heat pump technology.
CO 2 cross-critical air source heat pump is when summer operation, air cooler is as condenser, import is connected with exhaust outlet of compressor, exhaust outlet of compressor temperature higher (100-150 DEG C), when carrying out heat exchange with air, owing to air themperature in summer is of a relatively high, need bigger heat exchange area, simultaneously, air cooler outlet connects expansion valve, according to actual measurement situation, expansion valve inlet temperature is the lowest, system effectiveness is the highest, when expansion valve inlet temperature is less than 35 DEG C, system effectiveness can reach 4, 2-4.5, therefore Temperature of Working before expansion valve is reduced, reduce air cooler outlet enthalpy and can be greatly improved system effectiveness.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, reliable fall enthalpy system, it is possible to before reducing expansion valve, the carbon dioxide air source heat pump evaporation of working medium enthalpy sends out fall enthalpy system.
This utility model be the technical scheme is that enthalpy system drops in a kind of evaporation for air source carbon dioxide heat-pump, include and circulated the water tank of connection, evaporation jet head sets and water pump by pipeline successively, wherein, described evaporation jet head sets is arranged on the top carrying out the air cooler in the carbon dioxide air source source pump lowered the temperature for the fog sprayed by evaporation jet head sets.
The water inlet of described water tank connects the drain pipe of indoor set condensed water.
The discharge for regulating the condensed water flowing to evaporation jet head sets and the regulation valve of pressure it is provided with on the described pipeline between evaporation jet head sets and water tank.
A kind of carbon dioxide air source heat pump evaporation of the present utility model sends out fall enthalpy system, utilize water evaporation endothermic principle and the higher feature of critical-cross carbon dioxide air source heat pump delivery temperature, evaporation fall enthalpy system is set up outside heat pump air cooler, carbon dioxide temperature in the heat pump air cooling heat exchanger of carbon dioxide air source when absorbing cooling in summer, reduce the temperature before carbon dioxide enters expansion valve, reduce working medium enthalpy, reduce and expand the loss brought, thus be greatly improved system whole efficiency.Meanwhile, enhance air cooler heat exchange efficiency, reduce air cooler heat exchange area, save equipment size, save equipment cost.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, a kind of carbon dioxide air source heat pump evaporation of the present utility model is sent out fall enthalpy system to be described in detail.
As shown in Figure 1, a kind of carbon dioxide air source heat pump evaporation of the present utility model sends out fall enthalpy system, include and circulated the water tank 2 of connection, evaporation jet head sets 4 and water pump 3 by pipeline successively, wherein, described evaporation jet head sets 4 is arranged on the top carrying out the air cooler 6 in the carbon dioxide air source source pump 1 lowered the temperature for the fog sprayed by evaporation jet head sets 4, and the water inlet of described water tank 2 connects the drain pipe of indoor set condensed water.The discharge for regulating the condensed water flowing to evaporation jet head sets 4 and the regulation valve 5 of pressure it is additionally provided with on pipeline between described evaporation jet head sets 4 and water tank 2.
Enthalpy system drops in a kind of evaporation for air source carbon dioxide heat-pump of the present utility model, during installation, first determines the quantity of all parts, size according to the heat exchange scale of carbon dioxide air source source pump 1；Then water tank 2, water pump 5 are fixed, evaporation jet head sets 4 is installed at the top of the air cooler 6 in carbon dioxide air source source pump 1, connect water pump 3, evaporation jet head sets 4, water tank 2 and regulation valve 5, thus constitute complete carbon dioxide air source heat pump evaporation and send out fall enthalpy system.
Enthalpy System Working Principle drops in a kind of evaporation for air source carbon dioxide heat-pump of the present utility model, during summer operation, can indoor condensed water be caused in water tank 2, water in water tank 2 is delivered to evaporate jet head sets 4 by water pump 3, water is due to evaporation jet head sets 4 decompressing effect, atomization, on spray attachment air cooler 6 in carbon dioxide air source source pump 1, due to summer operation carbon dioxide delivery temperature the highest (100-150 DEG C), water loading evaporates rapidly on air cooler 6, absorb carbon dioxide heat in air cooler 6, so that the expansion valve inlet temperature in carbon dioxide air source source pump 1 reduces, improve system effectiveness, when expansion valve inlet temperature is less than 35 DEG C, system effectiveness can reach 4.2～4.5, therefore the work efficiency of carbon dioxide air source source pump 1 it is greatly improved.
A kind of evaporation for air source carbon dioxide heat-pump of the present utility model is dropped in enthalpy system, and unspent water is by Pipeline transport recovery tank 2, and this utility model with regulating water flow and pressure, thus can reach to regulate the purpose of the fogging degree of water by regulation valve 5.
