Abstract
The utility model discloses a low-temperature mobile dehumidifier adopting a direct ventilation defrosting method, which is characterized in that a compressor is connected with a condenser that is connected with a liquid receiver; the liquid receiver is connected with a thermostatic expansion valve which is connected with an evaporator; the evaporator is connected with the compressor; and a centrifugal fan is connected beside the condenser. The low-temperature mobile dehumidifier has the technical effects: due to the adoption of the direct ventilation defrosting method, having simple realization and easy use, avoiding the influence on the heat transfer of the evaporator due to defrosting by adopting electric heater or electrically heated tube as well as large air-out temperature fluctuation caused by electrically heated defrosting, avoiding uneven heating in defrosting, and greatly improving the service life of a unit.
Description
Technical field
The utility model relates to a kind of low form and moves dehumidifier, relates in particular to a kind of low form of direct ventilated type defrosting method that adopts and moves dehumidifier.
Background technology
At present; existing low form moves dehumidifier and generally adopts electrical heating defrosting mode that the evaporimeter of mobile dehumidifier is carried out defrosting; but adopt electric heater or heating tube all can bring certain influence to the normal heat exchange of evaporimeter; and adopt Electric heating often regular meeting the phenomenon of local heating's inequality appears; when defrosting; some position temperature has been elevated to the temperature of defrosting protection; but the frost layer at some position does not still eliminate; defrosting poor effect as a result, and the service life of having reduced unit.
Summary of the invention
The purpose of this utility model has been to provide a kind of low form of direct ventilated type defrosting method that adopts to move dehumidifier, it is big to the leaving air temp fluctuation that the influence and the electrical heating defrosting of the heat exchange of evaporimeter causes that this dehumidifier can avoid adopting electric heater or electric heating tube to carry out defrosting, and the uneven influence of being heated in the time of can avoiding defrosting to unit durability, and this method realizes simple, easily row.
The utility model is achieved like this, it comprises evaporimeter, heating power expansion valve, liquid reservoir, compressor, condenser, centrifugal blower, it is characterized in that compressor connects condenser, condenser connects liquid reservoir, liquid reservoir connects heating power expansion valve, heating power expansion valve connects evaporimeter, and evaporimeter connects compressor, and the condenser next door is connected with centrifugal blower.
Technique effect of the present utility model is: adopt direct ventilated type defrosting method, realize simple, convenient and easy, it is big to the leaving air temp fluctuation that the influence and the electrical heating defrosting of the heat exchange of evaporimeter causes that it has avoided adopting electric heater or electric heating tube to carry out defrosting, thus and the inequality of being heated can avoid defrosting time service life of having improved unit greatly.
Description of drawings
Fig. 1 is a fundamental diagram of the present utility model.
Evaporimeter 2, heating power expansion valve 3, liquid reservoir 4, compressor 5, condenser 6, centrifugal blower in the drawings, 1,
The specific embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises evaporimeter 1, heating power expansion valve 2, liquid reservoir 3, compressor 4, condenser 5, centrifugal blower 6, it is characterized in that compressor 4 connects condenser 5, condenser 5 connects liquid reservoir 3, and liquid reservoir 3 connects heating power expansion valve 2, and heating power expansion valve 2 connects evaporimeter 1, evaporimeter 1 connects compressor 4, and condenser 5 next doors are connected with centrifugal blower 6.During the operation of compression refrigeration unit, discharge behind the refrigerant gas of the compressed machine 4 boil down to HTHPs of the refrigerant gas of low-pressure low-temperature, enter condenser 5 be condensed into enter liquid reservoir 3 behind the highly pressurised liquid after, sucked back compressor 4 after entering evaporimeter 1 after the heating power expansion valve 2 throttling step-downs again to carry out heat exchange again with air, air then sucks through centrifugal blower 6, through evaporimeter 3, with reduce temperature after wherein the low pressure refrigerant heat exchange and separate out water, after through being sent so circulation after condenser 5 heating.
When mobile dehumidifier moves under low temperature environment, evaporimeter 3 frostings, then carry out defrosting when the frost layer is tied certain thickness, at this moment, compressor 4 is out of service, but centrifugal blower 6 still aspirates air, by forced ventilation, make the frost layer melt gradually and come off, after defrosting stops, compressor 4 is opened, and mobile dehumidifier normally moves.
