Shown in Fig. 2,3, air-conditioner capable of dehumidifying without cool-down of the present invention, this air-conditioning system comprises compressor 1, electromagnetism four-way change-over valve 2, external heat exchanger 3, filter 4, throttling electric expansion valve 5, indoor heat exchanger 6, wet magnetic valve 7 and outdoor fan 15, compressor 1 is by described electromagnetism four-way change-over valve 2 junction chamber external heat exchanger 3 successively, filter 4, throttling electric expansion valve 5 and indoor heat exchanger 6 and constitute the loop, and described indoor heat exchanger 6 has been divided into before and after indoor heat exchanger dehumidifying section 6a and the indoor heat exchanger bringing-up section 6b two sections by described dehumidifying magnetic valve 7.
For can Based Intelligent Control, being provided with plurality of temperature, humidity sensor in the air-conditioning system, is respectively indoor coil pipe sensor 8, indoor temperature transmitter 9, indoor humidity sensor 10, outdoor defrosting temperature sensor 11, outdoor ring temperature sensor 12, compressor exhaust temperature sensor 13 and compressor air suction temperature sensor 14.
Indoor coil pipe sensor 8 is positioned on the indoor heat exchanger dehumidifying section 6a, described indoor temperature transmitter 9 and indoor humidity sensor Room 10 are positioned on the indoor heat exchanger 6, described indoor humidity sensor 10 can detect space air humidity constantly, and intuitively show, described indoor temperature transmitter 9 is used to freeze and heats compressor frequency control under the operation mode, described outdoor defrosting temperature sensor 11 is between outdoor heat exchanger 3 and filter 4, and described outdoor ring temperature sensor 12 is being used for the control room rotating speed of dc fan 15 or the start-stop of AC blower fan except that wet condition.
Compressor in the refrigeration system 1 is the frequency-changeable compressor of rotating speed changeable type as shown in Figure 2.
Dehumidifying magnetic valve 7 in the system is a kind of open type heavy caliber magnetic valves, and according to the air-conditioner capacity, the valve port footpath is usually at 6～9mm.Under the no power state, the dehumidifying magnetic valve is in opening; Under "on" position, the electromagnetic force that is produced by the dehumidifying electromagnetic valve coil drives spool 16 and moves and close the dehumidifying magnetic valve, and by the sealing of the refrigerant pressure difference before and after valve dehumidifying magnetic valve.Have one or several apertures 17 on the spool of this dehumidifying magnetic valve, make the dehumidifying magnetic valve still have the cold-producing medium of certain flow to flow through in off position.The refrigerant flow design of the size of perforate and quantity closed condition as required.
Dehumidifying magnetic valve 7 is divided into two sections to indoor heat exchanger 6 among Fig. 2, is being known as dehumidifying section 6a and bringing-up section 6b again respectively except that these two sections of wet conditions.
The motor that drives outdoor fan 15 is for the driving of stepless speed regulation direct current generator or for having the tapped alternating current generator more than 2 grades.
At needs not during the cool-down dehumidification operation mode, controller control electric expansion valve 5 is in full-gear, 7 energisings of indoor dehumidification magnetic valve, dehumidifying closed electromagnetic valve, only by the circulation of the aperture on spool cold-producing medium, indoor dehumidification magnetic valve 7 plays throttling step-down cooling effect.Outdoor fan 15 carries out automatic wind speed by controller to be regulated.Rotation speed of fan is turned down in the reduction of the temperature that detects along with outdoor ring temperature sensor when adopting direct current generator usually.When adopting AC blower fan, with slow-speed of revolution running, when outdoor environment temperature is very low,, is controlled to be out one and stops alternate-running usually according to temperature levels, reach the requirement of dehumidifying by the time of regulating start-stop.Under this operation mode, since the rotating speed of outdoor fan 15 is lower or for the time stop transport when opening and change, cooling capacity is low, ejecting high-temperature high-pressure refrigerant from compressor 1 only has part to be condensed at outdoor heat exchanger 3, simultaneously because electric expansion valve 5 is in full-gear, cold-producing medium in the outdoor heat exchanger 3 can be easy to be transported to the bringing-up section 6b of indoor heat exchanger, and in fact indoor heat exchanger bringing-up section 6b has served as the part of refrigeration system condenser.Because the refrigerant temperature in indoor heat exchanger bringing-up section 6b, played heat effect to room air, himself is cooled to the liquid of supercooled state by room air, through the throttling hypotensive effect of dehumidifying magnetic valve 7, become the gas-liquid mixed refrigerant steam of low-temp low-pressure, at indoor heat exchanger dehumidifying section 6a, the cold-producing medium evaporative cooling, because its temperature is lower than the dew-point temperature of indoor air, the steam of room air just condenses at the dehumidifying section 6a of indoor heat exchanger, has reduced air humidity.Through being cooled the air mixing of drying with the indoor heat exchanger dehumidifying section 6a that flows through after, the heated air of indoor heat exchanger bringing-up section 6b blows out from indoor set.By the ratio of reasonable distribution dehumidifying section 6a and bringing-up section 6b, the air themperature temperature that blows out after can realizing mixing is identical with the inhaled air temperature or approaching, and humidity has obtained reduction, thereby realizes the not purpose of cool-down dehumidification.
In common refrigeration with heat operating condition, indoor dehumidification magnetic valve 7 no powers are in open mode, because the circulation bore of this valve is bigger, the flow through pressure loss of this valve of cold-producing medium can be ignored, and its existence can not influence normal refrigeration and heating effect.The throttling of this moment and refrigerant flow are regulated has electric expansion valve 5 to finish.
From removing wet condition when refrigerating state is changed, even if indoor dehumidification magnetic valve 7 outages, because the bore of dehumidifying magnetic valve 7 is bigger, the action of its spool is to be used for realizing by electromagnetic force and inner spring force thereof, when the dehumidifying running, dehumidifying magnetic valve two ends have this very big refrigerant pressure poor, spring be not enough to overcome the pressure of cold-producing medium at all, the dehumidifying valve core of the electromagnetic valve can't be got back to the normal position and promptly can't open.For addressing this problem; be designed in the control from removing wet condition when refrigerating state is changed, compressor is shut down processing, after about 1～3 minute; when the 7 front and back pressure balances of dehumidifying magnetic valve, spring force can spur is opening compressor after spool is got back to the normal position.And from refrigerating state when removing the wet condition conversion, because dehumidifying magnetic valve 7 front and back do not have pressure differential during refrigerating state, when to 7 energisings of dehumidifying magnetic valve, electromagnetic force is easy to spur spool to the closed position, and back in the closed position is along with the pressure differential at the running dehumidifying magnetic valve two ends of compressor can constantly increase to certain numerical value.This pressure differential plays the effect of sealed valve core again.Therefore in the time of from freezing to removing wet condition, design is directly changed in the control, need not to carry out compressor shutdown and handles.
Because the setting of indoor humidity sensor 10 can detect space air humidity constantly, and intuitively show.Height at start-stop that removes the wet condition compressor and operating frequency is controlled according to the deviation of current humidity and setting humidity fully, and when specific design was set humidity 10% for being lower than when current humidity, compressor was shut down processing.
Indoor temperature transmitter 9 is used for freezing usually and heats compressor frequency control under the operation mode.
Outdoor ring temperature sensor 12 is at the rotating speed of dc fan except that wet condition is designed to the control room 15 or the start-stop of AC blower fan.
