Description
Technical field
The present invention relates to the air-treatment field, particularly a kind of steam compression type dehumidifying equipment that uses in the hot and humid environment operating mode.
Background technology
As shown in Figure 1, the operation principle of general dehumidifier is as follows:
One, the interior circulation of dehumidifier: the operation by compressor 1 → exhaust outlet is discharged the gas of HTHP → enter condenser 11 and is cooled off → become normal temperature high voltage gas → by throttling arrangement 10 dam → the become liquid of low-temp low-pressure → become the gas of low-temp low-pressure by the evaporimeter 3 evaporations compressor 1 that absorbs heat → get back to.So move in circles.
Two, the outer circulation of dehumidifier: under the situation of normal boot-strap → operation → malaria by blower fan 9 from air inlet suction → process evaporimeter 3 → evaporimeter 3 airborne moisture content is adsorbed on the aluminium flake → become dry air → process condenser 11 dispel the heat → to blow out from air outlet.
At present, in the air-treatment field, the small-sized dehumidifier of making according to the steam compression type refrigeration principle particularly, because of noise is low, in light weight, efficient is high, occupation rate of market is a lot, the application of small-sized unit accounts for more than 90% of whole air dewetting unit output, applied environment roughly is divided into below 38 ℃, below 35 ℃, below 32 ℃.Have only seldom the producer of counting, according to the standard design of air-conditioning unit below 43 ℃.But all can not long-play, this is the operating condition critical line of dehumidifier just.The dehumidifier of using in the operating mode of high temperature (above 43 ℃) high humiditys (relative humidity 〉=90%) does not also have at present, particularly the small-sized unit of steam compression type.At industry, commercial field, can only adopt the dehumidification mode of bleeding of a large amount of heat energy of loss at present, very serious to the waste of fuel, produce CO simultaneously
2, SO
2Deng discharging, quite serious to atmospheric pollution.
Summary of the invention
The object of the invention provides a kind of steam compression type dehumidifying machine to dehumidify after the first precooling, and this dehumidifier can be used in hot and humid environment normally and efficiently.
For achieving the above object, the invention provides following technical scheme:
Dehumidifier comprises the compressor, condenser, throttling arrangement and the evaporimeter that connect and form the closed-loop path by pipeline in turn; Also comprise blower fan, blower fan is between the air inlet of the gas outlet of evaporimeter and condenser;
In addition, also comprise a pre-cooler, this pre-cooler comprises at least one water-cooled heat exchanger, tank and water pump; Described water-cooled heat exchanger is positioned at the front end of described evaporimeter airintake direction, tank is positioned at the below of described evaporimeter, water pump is positioned at tank, and the delivery port of water pump connects the water inlet of water-cooled heat exchanger, and the delivery port of water-cooled heat exchanger inserts tank by pipeline.
Above-mentioned dehumidifier has been set up pre-cooler on the basis of original dehumidifier, malaria is tentatively lowered the temperature through the water-cooled heat exchanger in the pre-cooler earlier, carry out drying, cooling entering evaporimeter then, and can be assembled in the screw clamp by the condensed water that the evaporimeter surface condensation becomes, these condensed waters are in that water pump suction water-cooled heat exchanger is arranged, as the low-temperature receiver of precooling.Certainly, also cold water can be added in advance in tank, as the low-temperature receiver of water-cooled heat exchanger.Owing to increased pre-cooler, this dehumidifier can be used in hot and humid environment normally and efficiently.
Further technical scheme is,
Described throttling arrangement is a heating power expansion valve.
Compare with capillary, the pressure adjustable range of heating power expansion valve is bigger, and can also regulate the liquid supply rate of evaporimeter automatically, and the thermic load of liquid supply rate and evaporimeter is complementary.
Description of drawings
Fig. 1 is the structure chart of existing dehumidifier;
Fig. 2 is the structure chart of dehumidifier of the present invention.
The invention will be further described below in conjunction with drawings and Examples.
The specific embodiment
Referring to Fig. 2, dehumidifier comprises compressor 1, condenser 11, fluid reservoir 8, throttling arrangement 10, evaporimeter 3 and the gas-liquid separator 2 that connects and form the closed-loop path by pipeline in turn.Also comprise blower fan 9, blower fan 9 quickens flowing of air between the air inlet of the gas outlet of evaporimeter 3 and condenser 11.Dehumidifier also comprises a pre-cooler, and this pre-cooler comprises a water-cooled heat exchanger 4, tank 6 and water pump 5.Water-cooled heat exchanger 4 is positioned at the front end of evaporimeter 3 airintake directions.Tank 6 is positioned at the below of evaporimeter 3.Water pump 5 is positioned at tank 6, and the delivery port of water pump connects the water inlet of water-cooled heat exchanger 4.The delivery port of water-cooled heat exchanger 4 inserts tank 6 by pipeline.The top of tank 6 is provided with overfall, and overfall is connected with drainpipe 7.Also be provided with the water level switch 12 of control water level in the tank 6, this water level switch 12 can be float-type or electric pole type.Throttling arrangement can be selected heating power expansion valve or capillary herein, preferred heating power expansion valve.
When above-mentioned dehumidifier is worked, three working medium circulations, i.e. cold-producing medium, empty G﹠Ws are arranged.The cyclic process of cold-producing medium is, elder generation enters condenser 11 by the gas that compressor 1 is compressed into HTHP, in condenser 11, liquefy, liquid after the liquefaction enters fluid reservoir 8, enter evaporimeter 3 heat absorptions through throttling arrangement 10 again and flash to gas, get back to gas-liquid separator 2, enter compressor 1 at last and move in circles.The cyclic process of extraneous air is, hot and humid air through water-cooled heat exchanger 4, dehumidifies into dry Cryogenic air on evaporimeter 3 surfaces earlier again, through condenser 11 heating after blower fan is blown in the air or in the air channel.The cyclic process of water is, the condensed water that becomes in evaporimeter 3 surface condensations gathers in the tank 6, and when condensed water reached a certain amount of, water level switch 12 actions were flowed out through drainpipe 7 by overfall.When intake air temperature reached setting value, water pump 5 was transported to water in the water-cooled heat exchanger 4 by the road, and the water outlet of water-cooled heat exchanger 4 returns tank 6, formed circulation.This situation progressively realizes in the elevation process in environment temperature.
When hot and humid operating mode is dehumidified, can in tank 6, inject cold water earlier, simultaneously the operating temperature of water pump 5 is set to Current Temperatures and gets final product.
More than implement to be considered to limiting the scope of the invention, the present invention also has some other distortion.Can whether adopt according to compressor size or concrete condition decision as gas-liquid separator and fluid reservoir; And water-cooled heat exchanger quantity can be more than one, or the like.If those skilled in the art is subjected to inspiration of the present invention, the distortion that does not need creative work to make all should be implemented in protection domain of the present invention.
