The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.A kind of dehumidifier comprises compressor 1, outdoor heat exchanger 2, indoor first heat exchanger 3, indoor second heat exchanger 4, cross valve 5 and capillary 6; Described cross valve is communicated with compressor, outdoor heat exchanger, indoor first heat exchanger, indoor second heat exchanger respectively; The pipeline of described cross valve and indoor second heat exchanger 4 and outdoor heat exchanger 2 is provided with magnetic valve 7; Described capillary arranges on the pipeline between outdoor heat exchanger and indoor second heat exchanger.Pipeline between described indoor first heat exchanger and the cross valve is provided with and connects valve 8.Pipeline between described capillary and indoor second heat exchanger is provided with and connects valve 9.
The circulative metabolism of this utility model is divided into two kinds: one, the interior circulation of dehumidifier: the operation by compressor-exhaust outlet get rid of HTHP gas-entering condenser cools off-becomes low temperature high pressure gas-hold back-become the liquid of low-temp low-pressure-become the gas of low-temp low-pressure by the evaporator evaporation compressor that absorbs heat-get back to, and so forth by capillary.Two, dehumidifier outer circulation: under the situation of normal boot-strap-operation-malaria by blower fan from air inlet suck-pass through evaporimeter-evaporimeter with airborne water adsorption on aluminium flake-become dry air-process condenser dispel the heat-to blow out from air outlet.
Concrete work operational mode of the present utility model is as follows:
1, cool-down dehumidification pattern
When indoor temperature and humidity all than higher, and indoor refrigeration duty is when bigger, system runs on the cool-down dehumidification pattern, at this moment, cross valve is not charged, and the refrigeration modes operation is pressed by system, and the indoor second heat exchanger branch road is that magnetic valve turn-offs, outdoor heat exchanger is condenser, and indoor first heat exchanger is equivalent to evaporimeter.Room air becomes in the air return chamber of low temperature and low humidity only by the indoor first heat exchanger cool-down dehumidification.Under this pattern, air quantity or the water yield that can also the conditioning chamber external heat exchanger be further regulated refrigerating capacity and moisture removal, and refrigerating capacity and moisture removal all rise along with the increase of outdoor heat exchanger air quantity or the water yield.
