Description
Technical field
The utility model is related to a kind of dehumidifier, more particularly to a kind of dehumidifying that can be used under less than 12 DEG C of low temperature environment
Device.
Background technology
In some low temperature places, some materials are such as；Medicine, meat requires that humidity is maintained within the scope of one, conventional
Dehumidifier can not be run in this context, it is necessary to a kind of dehumidifier that can be worked under low temperature and low humidity environment.Existing dehumidifier,
Because the area of evaporator is smaller, and the area of condenser is larger, when these will cause unit operation, evaporator frosting quickly,
And then freeze, and conventional dehumidifier defrost is that nature defrost causes the frost above evaporator to be difficult to melt, last unit low pressure is protected
Shield can not be run.
The content of the invention
Technical problem to be solved in the utility model is how product to be dehumidified at low ambient temperatures.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of for removing under low temperature environment
Wet device, it is characterised in that including for by the compressor of gaseous coolant boosting heating, evaporator, for making after boosting heating
Gaseous coolant is condensed into the indoor condenser of liquid, for the swollen of feeding outdoor evaporator to be throttled and circulated to liquid refrigerants
Swollen valve and filter, the port of export of compressor pass through the entrance point of four-way valve connection compressor, evaporator top, condenser top
Portion, evaporator, condenser bottom connection expansion valve, expansion valve is also connected with the entrance point of compressor；Compressor, evaporator are located at
The refrigerant for room air to be sucked in evaporator and condenser inside unit is additionally provided with housing, in housing and carries out hot friendship
The air exhauster changed.
Preferably, the entrance point of the compressor, the port of export are respectively equipped with a needle-valve.
Preferably, the evaporator is finned evaporator.
Preferably, the condenser is finned cooler.
Preferably, the expansion valve is heating power expansion valve.
Preferably, the condenser connects the input of expansion valve by filter.
Preferably, environment temperature Temperature Humidity Sensor and defrost temperature sensor are provided with the housing at evaporator.
The utility model increases the area of evaporator, and the area of condenser is reduced, and the low pressure and high pressure of such unit are all
Within normal range (NR), slow frosting on evaporator, when the surface temperature of evaporator is less than -8 DEG C, unit is commutated with four-way valve
Defrost, quickly melts frost within a few minutes, so as to ensure that unit normally dehumidifies operation.Air can be entered at low ambient temperatures
Row dehumidifying, can be widely used in pharmaceuticals industry, and food refrigerated industry.
Compared with prior art, the beneficial effects of the utility model are：
1st, Cryogenic air closed circulation can be achieved to dry, dry materials quality is good.By the operating mode of control device, make drying
The temperature of the dry air of room is between 0 ~ 12 degree, and the low-temperature storage that can meet many materials dries requirement；The closing of dried medium
Circulation, can avoid polluting the impurity that material web comes with ambient atmos clearing house, this is outstanding to food, medicine or biological products
Its is important；
2nd, humidity regulation is convenient.The control system that unit is designed in itself humid control can be needed in a client one
In straight scope；
3rd, it is environment-friendly.Dried medium closed circulation wherein in the present apparatus, without material dust, without volatile materials
And the pollution that peculiar smell waste gas is brought to environmental emission；The thermal pollution of unit not to environment.
Brief description of the drawings
The structured flowchart for the dehumidifier being used under low temperature environment that Fig. 1 provides for embodiment.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figure 1, a kind of dehumidifier being used under low temperature environment provided for the utility model, it includes being used for gas
State refrigerant boosting heating compressor 1, evaporator 2, for make boosting heat up after gaseous coolant be condensed into the indoor cold of liquid
Condenser 3, expansion valve 4 and filter 6 for feeding outdoor evaporator to be throttled and circulated to liquid refrigerants, compressor 1
The port of export connects the entrance point of compressor 1, the top of evaporator 2, the top of condenser 3, evaporator 2, condenser 3 by four-way valve 5
Bottom connects expansion valve 4, and entrance point of the expansion valve 4 also with compressor 1 is connected；Compressor 1, evaporator 2 are in housing, housing
Inside it is additionally provided with the air exhauster that the refrigerant for room air to be sucked in evaporator and condenser inside unit carries out heat exchange
7.Environment temperature Temperature Humidity Sensor and defrost temperature sensor are provided with housing at evaporator 2.Condenser 3 passes through filter 6
Connect the input of expansion valve 4.Entrance point, the port of export of compressor 1 are respectively equipped with a needle-valve 8.The evaporator 2 is fin
Formula evaporator.The condenser 3 is finned cooler.The expansion valve 4 is heating power expansion valve.
The operation principle of low temperature dehumidification device that the present embodiment is provided is：By allowing refrigerant constantly to complete to evaporate suction chamber inner ring
Heat in border → compression → is condensate in releasing heat → throttling → heat evaporated on an evaporator again on unit internal condensation device
Power cyclic process, so that Moisture converting in inner cryogenic environment is flowed out into condensed water in unit water pond, refrigerant is in compression
In system internal circulation flow in the presence of machine.Arrow in Fig. 1 is gas flow direction.
Refrigerant completes gaseous boosting temperature-rise period in compressor, and then condenser is discharged after heat indoors, together
When oneself be cooled and be converted into flow liquid state, rerun to after evaporator, liquid evaporation of absorbing heat rapidly is again converted to gaseous state, together
When air moisture condensed on evaporator fin in inflow water pond, while indoor relative humidity is also reduced.
