Description

Evaporate cold low form total heat recovery Air-Cooled Heat Pump Unit
Technical field
The utility model relates to technical field of heat pumps, and in particular to a kind of cold low form total heat recovery air-cooled heat pump machine of evaporation Group.
Background technique
Currently, air-conditioner set mainly has following three kinds of types of cooling:
Air cooling way passes through the air-conditioning of air cooling fin heat exchanger and refrigerant heat exchange cooling using ambient outdoor air.
Water-cooling pattern, cooling water and refrigerant heat exchange after being cooled down using cooling tower are cooled down, this process generally exists It is completed in shell and tube condenser.
Cold mode is evaporated, is cooled down with cooling water direct boiling to refrigerant also with cooling water and refrigerant heat exchange, The cold mode of evaporation is that cooling water is directly sprayed in the surface of condenser unlike water-cooling pattern essence, utilizes the vaporization of water Latent heat takes away heat and improves the cooling water of unit time unit mass and the heat exchange amount of refrigerant, to improve unit efficiency.
In these three types of cooling, under cooling in summer mode, identical cooling capacity is obtained, using the unit for evaporating cold mode The energy consumption of (evaporation cold group) is minimum.Normally, identical cooling capacity is obtained, evaporation cold group is (multi-joint compared to air-cooled unit Unit) 30% or more energy conservation, compared to 15% or more unit (water chiller) energy conservation using water-cooling pattern (water -- water coke slurry).
When the air-conditioner set of these three types of cooling is run in cooling mode, the thermal energy that compressor work is generated is needed It is discharged into outdoor environment, these amount of heat being discharged (thermal energy) are consumption electric energy productions, if being discharged into atmosphere In thermal energy can be obtained a large amount of free energy as " byproduct " recycling of refrigeration unit, thus reduce client's use at This.
Traditional Air-Cooled Heat Pump Unit compressor is all the refrigeration compressor being once pressurized that commonly freezes, due to refrigeration compressor When outdoor environment temperature is lower than -5 DEG C, heat pump unit efficiency is substantially reduced when using as heat pump, the unit when spending lower than -12 Efficiency is almost " 0 ", therefore limits use scope and the region of heat pump.
Since evaporation cold group is evolved by water cooler, in terms of refrigeration and water chiller, especially compared with wind There is significant advantage in terms of cold refrigeration, but using evaporation cold group as the heat pump unit that can either freeze and can heat When, there are following two aspects drawbacks:
On the one hand, due to being to absorb saturated steam in air with cooling water under evaporation cold group in winter heating mode " condensation heat " of middle release is as heat source, since heat exchange efficiency is very low, until making to evaporate cold group in winter under heating mode Energy consumption is higher.
On the other hand, due to the freezing point of cooling water be 0 DEG C, when environment temperature be lower than 0 DEG C, cool water shower to condenser table Face will be frozen, and cause evaporation cold group only could normally heat in the area that environment temperature is 0 DEG C or more, limiting makes Use region.
The process of air-conditioner set thermodynamic cycle is the process that cooling capacity, heat shift between evaporator and condenser, system Cold inverse cyclic process is to heat, and evaporating cold refrigeration unit only realizes one of function, so evaporation cold-heat pump technology It is left to be desired.
From above-mentioned analysis it is found that how to develop a kind of heat pump unit, there is efficient refrigeration, low-temperature heating, the energy can return It receives and utilizes to save the energy, reduce customer using cost, it has also become those skilled in the art's technical issues that need to address.

That is, refluxing opening is connected to one end of the second heat exchanger 9.
In this case, compressor 1 starts, and the feeding spraying pump 12 for evaporating cold heat exchange unit starts, and blower 11 starts, the One solenoid valve 16 is closed air cooling heat exchanger 3 and is closed, and second solenoid valve 17 opens evaporation cold heat exchanger 4 and is in heat exchange state, into And ensure to evaporate cold heat exchange unit to outdoor heat exhaust.
Preferably, in the present embodiment, air cooling heat exchanger 3 and evaporation cold heat exchanger 4 are in parallel connection.
Compressor 1 is powered on, and from 1 gas outlet of compressor, injection high temperature and high pressure gaseous refrigerant enters the first four-way valve 2 Enter the second four-way valve 29 later, enters the one end for evaporating cold heat exchange unit later.Since one end of air cooling heat exchanger 3 has the One end of one solenoid valve 16, evaporation cold heat exchanger 4 is connected to the side of the first solenoid valve 16 by second solenoid valve 17, evaporates cold The other end of heat exchanger 4 is connected to the other side of the first solenoid valve 16.First solenoid valve 16 is closed and second solenoid valve 17 is opened, Therefore, air cooling heat exchanger 3 is in parallel with evaporation cold heat exchanger 4, but refrigerant is without air cooling heat exchanger 3, so that air cooling heat exchanger 3 It is in standby;Refrigerant is through pervaporation cold heat exchanger 4 and carries out heat release, so that steam state high-temperature high-pressure refrigerant starts A large amount of condensations are to make refrigerant discharge heat in air;Later by the laggard of the 4th solenoid valve 22 and the first check valve 20 Enter fluid reservoir 5.
In the implementation with economizer 14, refrigerant is divided into major loop and the auxiliary circuit EVI after entering fluid reservoir 5:
In major loop, refrigerant passes through the 4th connector and its third connector after fluid reservoir 5 by economizer 14 Afterwards by the first expansion valve 8 be reduced to low-temperature low-pressure refrigerant liquid refrigerant by second one-way valve 18 and the 6th solenoid valve 24 into Enter the second heat exchanger 9, refrigerant vapor passes through the reflux for entering compressor 1 by the second four-way valve 29 after flashing to low temperature and low pressure steam Mouthful, carry out next circulation.
It assists in the circuit EVI, refrigerant is by passing through third solenoid valve 15 and electric expansion valve 7 after fluid reservoir 5, later By the first connector and the second connector of economizer 14, become medium pressure steam through overcompression after further vaporization The EVI jet port of machine 1 enters compressor 1 and completes a circulation.
As shown in figure 13, in the implementation for not having economizer 14, refrigerant enters after fluid reservoir 5 by the first expansion Valve 8 is reduced to low-temperature low-pressure refrigerant liquid refrigerant and enters the second heat exchanger 9 by second one-way valve 18 and the 6th solenoid valve 24, Refrigerant vapor passes through the refluxing opening for entering compressor 1 by the second four-way valve 17 after flashing to low temperature and low pressure steam, carries out next Circulation.
Wherein, without First Heat Exchanger 26.Therefore, the first above-mentioned mode can be used as individual refrigerating function mould Formula.
As shown in figure 3, in the second mode, which is heating mode.Third solenoid valve 15, the 4th solenoid valve 22 and 6th solenoid valve 24 is opened, and the 5th solenoid valve 23 and the 7th solenoid valve 25 are closed.
The first interface A of first four-way valve 2 is connected to its 4th interface D, and second interface B is connected to its third interface C. That is, outflow port is connected to by the first four-way valve 2 with one end of the second heat exchanger 9, one end of First Heat Exchanger 26 and refluxing opening connect It is logical.The first interface A of second four-way valve 29 is connected to its second interface B, and third interface C is connected to its 4th interface D.That is, Refluxing opening is connected to the one end for evaporating cold heat exchange unit, and one end of the second heat exchanger 9 is connected by the first four-way valve 2 with refluxing opening It is logical.
