Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the principle schematic according to temperature regulating dehumidifier group of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, according to temperature regulating dehumidifier group of the present utility model, comprise the compressor 1, condenser 2, the evaporimeter 5 that are connected by refrigerant pipe, condenser 2 is water-cooled condenser, the temperature regulating dehumidifier group also comprises the cooling water of recycle-water cool condenser, and is used for the reheater 9 to the processing of the air temperature-adjustment behind evaporimeter 5 cool-down dehumidifications; The temperature regulating dehumidifier group also comprises the cooling tower 12 to water quench, is provided with the first magnetic valve 8 on the cooling water pipeline between water-cooled condenser and the reheater 9, is provided with the second magnetic valve 10 on the cooling water pipeline between water-cooled condenser and the cooling tower 12.Temperature regulating dehumidifier group of the present utility model, by the reheater 9 that the cooling water of water-cooled condenser is recycled is set, thereby the air after can utilizing cooling water to evaporimeter 5 dehumidifying and coolings heats again, effectively reduces energy consumption.In addition, the first magnetic valve 8 and the second magnetic valve 10 are set respectively on the cooling water pipeline between water-cooled condenser and reheater 9, water-cooled condenser and the cooling tower 12, thereby can independently control the two flow and flow velocity, overcome the shortcoming that plain triple valve flow and flow velocity can't be controlled simultaneously, improve control accuracy.
Generally speaking, the rate of discharge of valve and flow velocity are subjected to two factor affecting: rear tube roadlock power and valve opening.Under normal conditions, rear tube roadlock power is generally just determined during fabrication.Two delivery ports of triple valve are controlled simultaneously, and between not separate, namely the aperture of two delivery ports also is mutual complementation, namely open how much greatly for one, what another just turns down accordingly, this means under each state, the distribution of flow velocity and flow is corresponding a kind of valve opening only all, unless adjust rear tube roadlock power by miscellaneous equipment.Therefore can there be the temperature blind spot in the adjusting of electronic ratio triple valve, be after the temperature regulating dehumidifier group presets temperature value, the aperture of two delivery ports by the control triple valve can't reach default stationary value or best temperature range, so the not hommization of this regulative mode and intellectuality.
The utility model is by adopting two motor-driven valves to control separately, the specification of external pipeline and control valve is selected very flexible, the selection of the situation lower valve of same traffic and flow velocity has different combinations with aperture, for example: under a certain flow, different according to the aperture of two valves, the whole water resistance of delivery port is also different, we can test by experiment, obtain the little combination of water resistance, and water resistance is little, the reliability of equipment is just high, and less resistance also can reduce the power consumption of water pump.On the little basis of water resistance, respectively two valves are controlled separately again, according to the actual temperature needs, regulate and control respectively the aperture size of two valves, make temperature reach optimum value, the temperature blind spot that brings in the time of can avoiding utilizing triple valve like this can reach any optimum value, control more accurately, make heat transfer effect more abundant.
The temperature regulating dehumidifier group also comprises device for drying and filtering 3 and the heating power expansion valve 4 that is connected between condenser 2 and the evaporimeter 5, and the temperature regulating dehumidifier group also comprises bassoon filter 6 and the gas-liquid separator 7 that is connected between evaporimeter 5 and the compressor 1.
In temperature regulating dehumidifier group of the present utility model, comprise two circulations, i.e. refrigerant circulation and cooling water circulation.Wherein the operation principle of refrigerant circulation is roughly as follows: the pressurized gas refrigerant that compressor 1 is discharged enters water-cooled condenser, gaseous coolant is condensed into liquid refrigerants in water-cooled condenser, flow through and enter evaporimeter 5 and air heat-exchange behind device for drying and filtering 3 and the heating power expansion valve 4, thereby airborne steam is in a liquid state in the evaporator surface condensation, thereby realize making air dewetting, enter compressor after refrigerant is processed through the drying of 6 filtrations of bassoon filter and gas-liquid separator 7 and finish refrigerant circulation.
The operation principle of cooling water circulation is roughly as follows: the cooling water outlet part of condenser 2 is by the first magnetic valve 8 reheater 9 of flowing through, realization is to the again heat of air, be discharged to cooling tower 12 coolings, another part directly is discharged into the pipe-line systems such as cooling tower 12 or water heater and uses by the second magnetic valve 10 again.
The main following steps of temperature regulating dehumidifier group control method of the present utility model: step 1: detect by the leaving air temp after reheater 9 temperature adjustments by the temperature sensor that temperature regulating dehumidifier group air outlet is set; Step 2: leaving air temp and the predefined temperature of user or temperature range are compared; Step 3: control the aperture of the first magnetic valve 8 and the second magnetic valve 10 according to comparative result by controller, thereby regulate the hot water amount who enters in the reheater 9, and then the temperature (being leaving air temp) of the air after adjusting and reheater 9 heat exchange.
When leaving air temp is lower than preset temperature range, the aperture of controlling the first magnetic valve 8 by controller increases, and the aperture of controlling the second magnetic valve 10 reduces, thereby increase the hot water flow that enters in the reheater 9, heat exchange amount between the heat exchange coil of increase air and reheater 9, thereby the raising leaving air temp guarantees that leaving air temp accurately is controlled in the preset range.
When leaving air temp was positioned at preset temperature range, the aperture of controlling the first magnetic valve 8 and the second magnetic valve 10 by controller was constant, was arranged in preset temperature range thereby effectively control leaving air temp.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
According to temperature regulating dehumidifier group of the present utility model, by the reheater that the cooling water of water-cooled condenser is recycled is set, thereby the air after can utilizing cooling water to the evaporimeter dehumidifying and cooling heats again, effectively reduces energy consumption.In addition, the first magnetic valve and the second magnetic valve are set respectively on the cooling water pipeline between water-cooled condenser and reheater, water-cooled condenser and the cooling tower, thereby can independently control the two flow and flow velocity, overcome the shortcoming that plain triple valve flow and flow velocity can't be controlled simultaneously, improve control accuracy.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
