Detailed description of the invention
As depicted in figs. 1 and 2, a kind of air conditioner water cold group system has scroll compressor 1, oil eliminator 2, water-cooled condenser 3, magnetic valve 4, heating power expansion valve 5, flooded evaporator 6, liquid-sighting glass 7, heating power expansion valve temperature sensing bag 8, current limliting capillary 9 and electric appliance control box 10.The exhaust outlet of scroll compressor 1 connects the import of oil eliminator 2 by pipeline I, the air entry of scroll compressor 1 connects the oil-out of oil eliminator 2 by pipeline II, the outlet of oil eliminator 2 connects the import of water-cooled condenser 3 by pipeline III, the outlet of water-cooled condenser 3 connects the import of flooded evaporator 6 by pipeline IV, the outlet of flooded evaporator 6 connects the air entry of scroll compressor 1 by pipeline V; Pipeline II is in series with liquid-sighting glass 7 and current limliting capillary 9, and wherein liquid-sighting glass 7 is connected with the oil-out of oil eliminator 2; Pipeline IV is in series with magnetic valve 4 and heating power expansion valve 5, and wherein the outlet of heating power expansion valve 5 connects the import of flooded evaporator 6, and the import of heating power expansion valve 5 connects the outlet of water-cooled condenser 3 by magnetic valve 4; On pipeline V, binding has heating power expansion valve temperature sensing bag 8; Electric appliance control box 10 is connected with compressor wiring box by cable.
The mounting structure of native system as shown in Figure 2, wherein, the Inlet and outlet water interface of flooded evaporator 6 adopts bottom in and top out, the Inlet and outlet water interface of water-cooled condenser 3 adopts bottom in and top out, 1# system water cool condenser outlet pipe and 2# system water inlet pipe are by pipeline UNICOM, 1# system evaporator outlet pipe and 2# system water inlet pipe, by pipeline UNICOM, form string reverse-flow, thus the performance of the performance 1# of equilibrium and 2# system.Water-cooled condenser 3 in this enforcement adopts horizontal shell and tube type water-cooled condenser.
The course of work: the cold-producing medium of unit is discharged from the exhaust outlet of scroll compressor 1 and I entered from the import of oil eliminator 2 by the road, the most of oil being mixed in cold-producing medium inside is filtered down through centrifugal force and gravity two gravity in oil eliminator 2 inside, through the air entry that its oil-out is converged to scroll compressor 1 by pipeline II, along with return-air air-flow enters compressor oil storage tank, cold-producing medium after separation flows out from a point outlet for oil eliminator 2, then water-cooled condenser 3 is entered by pipeline III inner, flow out from the outlet of water-cooled condenser 3 after exothermic condensation, then enter from the import of heating power expansion valve 5 through magnetic valve 4, flow out from the outlet of heating power expansion valve 5 after reducing pressure by regulating flow, then entered by the import of pipeline IV from flooded evaporator 6, the cold-producing medium entered and refrigerating medium are discharged from the outlet of flooded evaporator 6 after abundant heat exchange, the air entry to compressor is converged finally by pipeline V.
Flooded evaporator due to what adopt, the evaporation tube of flooded evaporator surface for liquid wetting, surface coefficient of heat transfer is large.Flooded evaporator tube side is leaked water, and shell side is the liquid refrigerant of transition, and heat exchange form is liquid and liquid heat exchange, and belong to large space evaporation and heat-exchange, heat transfer temperature difference is only 2 DEG C.In flooded evaporator, cold water flow is in pipe, and can reach turbulent condition, heat transfer coefficient is higher, for refrigerant in shell-side, is in fluidized state, and hot transfer efficiency greatly promotes.Flooded evaporator can exempt degree of superheat restriction, heat exchanger tube is moistened completely and is dipped in liquid refrigerants, take full advantage of effective disengagement area, evaporating temperature can improve 2 ~ 3 DEG C, unit efficiency obtains and promotes, and unit eer generally can reach 1 grade, country, thus reaches the effect of economize on electricity, low-carbon environment-friendly.Scroll compressor is with low cost, maintenance-free, totally enclosed type No leakage point.Heating power expansion valve is with low cost, control is simple, production technology is ripe, easy to maintenance.
By adopting the unit of the 20URT of this configuration to test to one, contrast with the close unit of other brands (in detail as table 1, table 2).
Table 1
Table 2
Be not difficult to find out that different evaporation structure form (heat transfer mechanism) still has very large great disparity, coefficient of performance maximum lift 22.5% in refrigerating capacity and the coefficient of performance, this operation to user consumption reduction has very large space.
