Description of drawings
Fig. 1 is in the utility model, the structural representation that the compressor air compensating system is connected with indoor set assembly, off-premises station assembly.
The specific embodiment
Embodiment one:
As shown in Figure 1, compressor air compensating system and indoor set assembly, off-premises station assembly connect to form complete refrigerant circulation loop.Described indoor set assembly comprises indoor heat exchanger 1 and expansion valve 2, and described off-premises station assembly comprises secondary cooling coil 16, throttle part 3 and outdoor heat exchanger 4, and described throttle part 3 is composed in parallel by expansion valve 5 and check valve 6.The compressor air compensating system is made up of enhancement mode air injection enthalpy-increasing digital scroll compressor 8 (hereinafter to be referred as compressor), reservoir 7, EVI magnetic valve 9, throttling arrangement 10, three temperature-sensitive bags, wherein throttling arrangement 10 is composed in parallel by EVI electric expansion valve 14 and check valve 15, connects by copper pipe between each parts.First interface of reservoir 7 connects throttling arrangement 10, second interface of reservoir 7 has connected first air entry that is connected to compressor 8 behind the off-premises station assembly, draw a pipeline from the 3rd interface of reservoir 7, this pipeline is drawn from reservoir 7 tops, and it has connected second air entry that is connected to compressor 8 behind the EVI magnetic valve 9.The first temperature-sensitive bag 11 is arranged on the copper pipe that connects compressor 8 second air entries and EVI magnetic valve 9, and the second temperature-sensitive bag 12 is arranged on the copper pipe that connects reservoir 7 and throttling arrangement 10, and the 3rd temperature-sensitive bag 13 is arranged on the fin of outdoor heat exchanger 4.
The air conditioner that uses this compressor air compensating system is when heating operation, the low-temperature low-pressure refrigerant that comes out from outdoor heat exchanger 4 through compressor 8 compressions after, in the scroll plate of compressor 8 with the refrigerant mixed that sucks from compressor 8 second air entries, continue to be compressed into the gas of HTHP then by compressor 8, high-temperature high-pressure refrigerant gas after the compression is flowed through behind indoor heat exchanger 1 and the electric expansion valve 2, being become gas-liquid mixture after 14 throttlings of EVI electric expansion valve enters reservoir 7, heat at reservoir 7 inner refrigerant GAS ABSORPTION refrigerant liquids reaches certain state, be used to be inhaled into compressor 8 second air entries, all the other cold-producing mediums are then through secondary cooling coil 16 coolings, flow into outdoor heat exchanger 4 after throttle part 3 throttlings and carry out heat exchange, first air entry of last compressed machine 8 flows into compressor 8 and participates in circulation next time.
The action principle of described reservoir is: the refrigerant air-liquid mixture through preliminary throttling enters after the reservoir 7, liquid gathers in reservoir 7 bottoms, and second interface that passes through reservoir 7 flows out reservoir, follow-up again through secondary cooling coil 16 coolings, inlet chamber external heat exchanger 4 after throttle part 3 throttlings, in reservoir 7, the heat that refrigerant gas absorbs liquid reaches certain state, when EVI magnetic valve 9 is opened, three interface of refrigerant gas by reservoir 7 enters compressor 8 through EVI magnetic valve 9 from second air entry of compressor 8, participates in circulation with all the other refrigerant mixed.In reservoir 7, the heat of refrigerant gas absorption refrigeration agent liquid, thus the refrigerant liquid degree of supercooling is increased, improve the degree of supercooling of whole circulation cold-producing medium, this system improves the heating capacity and the Energy Efficiency Ratio of whole system by increase the inspiratory capacity of compressor to the compressor tonifying Qi simultaneously.
Introduce EVI magnetic valve and EVI electronic Expansion Valve Control method below in detail.
At first in the controller of system, set two target temperature value T1, T2, the first temperature-sensitive bag 11 detects the temperature T 4 that connects compressor 8 and EVI magnetic valve 9 pipelines, the second temperature-sensitive bag 12 detects temperature T 5, the three temperature-sensitive bags 13 sensing chamber's external environment temperature T 3 that connect reservoir 7 and throttling arrangement 10 pipelines.
The target temperature value T1 that sets in difference T by relatively T4, T5 and the system controls the aperture of EVI electric expansion valve 14, thereby full liquid phenomenon can not appear in liquid level in the control reservoir, and the assurance compressor Wet Compression can not occur, guarantees the reliability service of compressor.Control the switching of EVI magnetic valve 9 by the relation of T2 and T3 relatively, but T3 is during smaller or equal to T2, EVI magnetic valve 9 is opened; As T3 during greater than T2, EVI magnetic valve 9 cuts out.When EVI magnetic valve 9 was opened, the refrigerant gas in the reservoir 7 participated in heating circulation with all the other refrigerant mixed in second air entry of EVI magnetic valve 9 by compressor 8 enters into the scroll plate of compressor 8.Unit is in operation, the temperature-sensitive bag is the detector tube channel temp constantly, system controller is constantly adjusted the aperture of EVI electric expansion valve 14 and the switching of EVI magnetic valve 9 according to the temperature comparative result, both guaranteed that air conditioner obtained good heating effect under worst cold case, guaranteed the reliability service of air conditioner again.
What need indicate is that any alteration of form or parts replacement that does not relate to basic structure and connected mode that the related personnel makes the utility model also belongs to protection domain of the present utility model.
