The many condensers provided by the present invention and double back wind bypass dehumidification fresh air group and air regulation side Method, it is possible to bring at least one beneficial effect following:
1, the present invention is during cooling in summer pattern uses, and outdoor new wind is in air-supply passage, through filtering Afterwards by the First Heat Exchanger cooling and dehumidifying used as vaporizer, reach required moisture content values, then Mixing with the part return air passing through to flow through the first return air bypass valve in air exhaust passage, wind pushing temperature raises And send into indoor;Indoor exhaust wind in air exhaust passage, after primary filter by use as condenser the Two heat exchangers (the second heat exchanger uses as main condenser herein) also take away condensation heat, and air themperature raises, In discharge chamber.Wherein, by utilizing the air draft of indoor lower temperature, high temperature refrigerant is condensed, effectively Reduce the condensation temperature of unit, utilize bypass return air to mix with cold air distribution simultaneously and carry out reheating, it is to avoid The cold consumption that cold-hot counteraction causes.
During present invention heating mode in the winter time uses, when indoor temperature is not up to predetermined temperature value, room Outer supplementary heat exchanger is opened, and the second heat exchanger cuts out, system enter in circulation pattern, First Heat Exchanger and auxiliary Helping the exchange roles of heat exchanger, First Heat Exchanger uses as condenser, and supplementary heat exchanger makes as vaporizer With.Indoor return air is entered in air supply duct by the second return air bypass valve, through use as condenser the One heat exchanger, after absorption condensation heat, temperature raises, and sends into indoor;Meanwhile, by opening supplementary heat exchanger Can quickly improve the ambient temperature of indoor.
When indoor temperature reaches predetermined temperature value, outdoor auxiliary condenser cuts out, and the second heat exchanger is opened, Entering outer circulation pattern, First Heat Exchanger and the exchange roles of the second heat exchanger, First Heat Exchanger is as condensation Device uses, and the second heat exchanger uses as vaporizer.Outdoor the most distinguished and the most admirable through using as condenser described the Heat up after one heat exchanger and be admitted to indoor;In described air exhaust passage;Indoor exhaust wind is after filtering by making The second heat exchanger used for vaporizer, temperature reduces, in discharge chamber, and row in low-temperature refrigerant absorption chamber The heat of wind air, is evaporated, and owing to indoor exhaust wind temperature relatively outdoor temperature is high, therefore improves to heat and is The evaporating pressure of system, improves the heating capacity of unit, reduces the power consumption of unit and avoids unit knot The risk of frost.
2, the present invention utilizes the air draft of indoor lower temperature to condense high temperature refrigerant when refrigeration, fall The low condensation temperature of unit, now make use of the sensible heat portion of energy of indoor exhaust wind, the most also utilizes part Bypass return air mixes with cold air distribution and carries out reheating, it is to avoid the cold consumption that cold-hot counteraction causes;And in system Time cold, indoor the second heat exchanger (as main condenser) and outdoor supplementary heat exchanger are applied in combination, altogether Condense with to high temperature refrigerant;And when heating, unit is cut between interior circulation and outer circulation pattern Changing, indoor temperature can be improved by interior circulation fast and effectively, and outside under circulation pattern, indoor higher temperatures The air draft of degree, as thermal source, improves the evaporating temperature of unit, and the second heat exchanger used as vaporizer is inhaled The heat receiving indoor exhaust wind is evaporated, and owing to the dew point temperature of indoor exhaust wind is higher, and evaporating temperature is relative The dew point temperature of air draft is relatively low, therefore has condensed water to separate out at the second heat exchanger surface, now reclaims not only It is the sensible heat portion of energy of indoor exhaust wind, has also reclaimed the latent heat portion of energy of indoor exhaust wind simultaneously.Thus, The energy of indoor exhaust wind can be made full use of, save the energy.
3, the present invention is under heating condition outer circulation pattern, outdoor new wind warp again after First Heat Exchanger heats up Cross wet film humidification module, make air humidity promote, meet indoor humidity requirement further, improve environment Comfort level.
4, the present invention is under cooling condition, suction superheat size the opening by the first electric expansion valve of compressor Degree controls, and the degree of supercooling size of the second heat exchanger is controlled by the aperture of the second electric expansion valve;Heating Operating mode, under interior circulation pattern, the suction superheat size of compressor is controlled by the aperture of auxiliary electron expansion valve System;Under heating condition, outer circulation pattern, the suction superheat of compressor is opened by the second electric expansion valve Degree controls, motility when improving actually used.
