Further, as shown in Figure 1, described first heat exchanging piece 2 is identical with the structure of described second heat exchanging piece 3, includes: coil pipe 10; And the heat exchange fin 11 be set on described coil pipe 10.Wherein, the coil pipe 10 of described first heat exchanging piece 2 is communicated with described inlet ductwork 5, the coil pipe 10 of described second heat exchanging piece 3 is communicated with described export pipeline 9, and the coil pipe 10 of described first heat exchanging piece 2 is communicated with by described connecting line 6 with the coil pipe 10 of described second heat exchanging piece 3.Coil pipe type and heat exchange fin material can be selected according to the actual demand of this area, are preferably fan coil and aluminum fin-stock in the present embodiment.
A/C evaporator in the present embodiment is when freezing, heating or work under dehumidification mode, and mainly by regulating the aperture of the first expansion valve 7 and the second expansion valve 8 to realize the constant temperature dehumidification in room, concrete constant temperature dehumidification process will be described below.It should be noted that, be easy to make the aperture of the first expansion valve 7 and the second expansion valve 8 regulate, two expansion valves of the present embodiment preferably adopt electric expansion valve herein.Electric expansion valve regulates evaporimeter liquid supply rate according to pre-set programs, belong to electronic type shaping modes, it has adapted to the electrical integrated demand for development of refrigeration machine, there is the good characteristic that heating power expansion valve is incomparable, for the intelligentized control method of refrigeration system provides condition, it is a kind of rising auto-control energy-saving element.
Further, for realizing regulating the aperture of two expansion valves, the A/C evaporator of the present embodiment also comprises the controller (not shown in figure 1) of the aperture for controlling two expansion valves, and this controller is generally placed in outside shell 1, so that user operation.In addition, controller controls expansion valve opening, and one of common function belonging to conventional controller, therefore adopts the conventional controller of this area in the utility model.Controller, will hereafter in conjunction with example explanation to the concrete adjustment of first expansion valve 7 of the present embodiment and the aperture of the second expansion valve 8.
Of the present utility model another embodiment still provides a kind of air-conditioning system, this air-conditioning system comprises above-mentioned A/C evaporator, more specifically, the inlet ductwork 5 of described A/C evaporator connects compressor, exhaust and cold-producing medium for making described compressor enter described first heat exchanging piece 2, and the export pipeline 9 of described A/C evaporator also connects compressor, the low temperature making to flow out in evaporimeter, low pressure refrigerant gas are finally back in compressor and are again compressed.Other common components of air-conditioning system, as compressor, condenser etc., can install with reference to the conventional air conditioning system of this area, the present invention does not repeat at this.
Below in conjunction with example, illustrate how above-mentioned A/C evaporator and air-conditioning system realize constant temperature dehumidification.For ease of illustrate, hereafter by air-conditioning system referred to as air-conditioning, the first heat exchanging piece side of the evaporimeter of Fig. 1 is called right side evaporimeter, the second heat exchanging piece side of evaporimeter is called left side evaporimeter, blower fan 4 is then placed in the middle of the evaporimeter of both sides.
As shown in Figure 2, the key step of carrying out constant temperature dehumidification control comprises:
S1, detects air conditioning operating mode.
In the present embodiment, air conditioning operating mode is divided into refrigeration mode, heating mode and dehumidification mode, and this Three models is the common operational mode of air-conditioning in prior art, therefore does not repeat the definition of each pattern and principle at this.
S2, judges whether air-conditioning is in dehumidification mode.
The constant temperature dehumidification of the present embodiment controls mainly to be divided into two parts, and one is the constant temperature dehumidification control under refrigerating/heating pattern, and two is the thermostatic controls under dehumidification mode.Therefore, need judge whether air-conditioning is in dehumidification mode by step S2.If testing result is neither refrigerating/heating pattern, neither dehumidification mode, then return step S1 and again detect.
S3, if air-conditioning is in dehumidification mode, then controls the second expansion valve 8 standard-sized sheet, and regulates the aperture of the first expansion valve 7 to reduce.
Composition graphs 1, under dehumidification mode, controller controls the second expansion valve 8 standard-sized sheet, right side evaporimeter is entered by inlet ductwork 5 from compressor exhaust out and cold-producing medium, and condensation heat release under blower fan 4 acts on, connecting line 6 is entered now from right side evaporimeter cold-producing medium out, because the aperture under the effect of controller of the first expansion valve 7 on connecting line 6 reduces, cold-producing medium can in the first expansion valve 7 adiabatic throttling (during the expansion valve that flow of refrigerant reduces through this unexpected aperture, the phenomenon that pressure reduces can be there is, be called throttling, and cold-producing medium has little time to carry out with the external world heat exchange in this process, can approx as adiabatic process process, therefore be called adiabatic throttling), cold-producing medium after decrease temperature and pressure enters left side evaporator evaporation heat absorption, meanwhile, blower fan 4 makes return air enter left side evaporimeter, return air temperature is made to decline and form condensation, namely the dehumidifying to return air is completed, return air after dehumidifying enters right side evaporimeter again, liberated heat when absorbing previous condensation of refrigerant heat release, return air temperature is raised, again the return air after intensification is sent into room, so far a complete space air constant temperature dehumidification process is completed.Wherein, by the effect of blower fan 4, the flow velocity of air can be increased, thus improve the heat exchange efficiency of both sides evaporimeter.
S4, if air-conditioning is not in dehumidification mode, then controls the first expansion valve 7 standard-sized sheet.
When air-conditioning is in refrigerating/heating pattern, controller controls the second expansion valve 8 and opens, the first expansion valve 7 standard-sized sheet, and under blower fan 4 acts on, the rapid heat exchange of both sides evaporimeter, is conducive to the object reaching refrigeration fast or heat.
The A/C evaporator of the present embodiment is under dehumidification mode, the constant temperature dehumidification of space air can be realized, avoid the problem affecting room comfortableness because traditional air conditioner causes wind pushing temperature lower in dehumidification process, can ensure that space air is in rational humidity range, and A/C evaporator structure is simple, be easy to control, energy-conserving and environment-protective.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
