-running action-
[0039] below, describes about the running action of the humidity control apparatus (10) of present embodiment.Specifically, the humidity control apparatus of present embodiment (10) dehumidifies and turns round and the humidification running.
[0040] and, being in the dehumidifying running or the humidification running in humidity control apparatus (10) outdoor air (OA) that has sucked is carried out feeding to as air supply (SA) after the humidity regulation indoor, the room air that will suck (RA) is as discharging air (EA) row to outdoor simultaneously.Just, be in the dehumidifying running or the humidification running in humidity control apparatus (10) carrying out indoor ventilation.
[0041] also have, all alternate repetition carries out the running of first state and second state turns round with time interval of defined (for example 3 minutes at interval) in the dehumidifying running and under any operating condition in the humidification running for above-mentioned humidity control apparatus (10).
[0042] above-mentioned humidity control apparatus (10) is if be in the dehumidifying running then suck respectively as the outdoor air (OA) of first air with as the room air (RA) of second air.Also have, above-mentioned humidity control apparatus (10) is if be in the humidification running then suck respectively as the room air (RA) of first air with as the outdoor air (OA) of second air.
[0043] at first, running describes about first state.In this first state running, send into second air, send into first air to first adsorption heat exchanger (51) respectively to second adsorption heat exchanger (52).In this first state running, carry out the regeneration action of first adsorption heat exchanger (51) and the absorption action of second adsorption heat exchanger (52).
[0044] shown in Fig. 1 (a), in the refrigerant loop (50) when above-mentioned first state turns round, four-way change-over valve (54) is set to first state.In case running compressor (53), then cold-producing medium circulates in refrigerant loop (50).Specifically, the cold-producing medium from compressor (53) ejection condenses after the heat release first adsorption heat exchanger (51).Curdy cold-producing medium is depressurized by expansion valve (55) time in first adsorption heat exchanger (51), heat absorption back evaporation in second adsorption heat exchanger (52) then.Vaporized cold-producing medium compresses after being inhaled into compressor (53) in second adsorption heat exchanger (52), and is sprayed from compressor (53) once more.
[0045] so, in the refrigerant loop (50) when first state turns round, first adsorption heat exchanger (51) becomes condenser, and second adsorption heat exchanger (52) becomes evaporimeter.In first adsorption heat exchanger (51), the adsorbent on fin (57) surface is by the heating of the cold-producing medium in the heat-transfer pipe (58), and the moisture that spins off from the adsorbent that has been heated is provided for second air.On the other hand, in second adsorption heat exchanger (52), the first airborne moisture is absorbed by the adsorbent on fin (57) surface, and the heat of adsorption that has produced is absorbed by the cold-producing medium in the heat-transfer pipe (58).
[0046] and, if be in the dehumidifying running, first air that then has been carried out dehumidifying in second adsorption heat exchanger (52) feeds to indoor, arranges to outdoor with second air from the moisture that first adsorption heat exchanger (51) spins off.On the other hand, if be in the humidification running, second air that then has been carried out humidification in first adsorption heat exchanger (51) feeds to indoor, and first air row that moisture has been absorbed by second adsorption heat exchanger (52) is to outdoor.
[0047] then, running describes about second state.In this second state running, send into first air, send into second air to first adsorption heat exchanger (51) respectively to second adsorption heat exchanger (52).In this second state running, carry out the regeneration action of second adsorption heat exchanger (52) and the absorption action of first adsorption heat exchanger (51).
[0048] shown in Fig. 1 (b), in the refrigerant loop (50) when above-mentioned second state turns round, four-way change-over valve (54) is set to second state.In case running compressor (53), then cold-producing medium circulates in refrigerant loop (50).Specifically, the cold-producing medium from compressor (53) ejection condenses after the heat release second adsorption heat exchanger (52).Curdy cold-producing medium is depressurized by expansion valve (55) time in second adsorption heat exchanger (52), heat absorption back evaporation in first adsorption heat exchanger (51) then.Vaporized cold-producing medium compresses after being inhaled into compressor (53) in first adsorption heat exchanger (51), and is sprayed from compressor (53) once more.
[0049] so, in refrigerant loop (50), second adsorption heat exchanger (52) becomes condenser, and first adsorption heat exchanger (51) becomes evaporimeter.In second adsorption heat exchanger (52), the adsorbent on fin (57) surface is by the heating of the cold-producing medium in the heat-transfer pipe (58), and the moisture that spins off from the adsorbent that has been heated is provided for second air.On the other hand, in first adsorption heat exchanger (51), the first airborne moisture is absorbed by the adsorbent on fin (57) surface, and the heat of adsorption that has produced is absorbed by the cold-producing medium in the heat-transfer pipe (58).
[0050] and, if be in the dehumidifying running, first air that then has been carried out dehumidifying in first adsorption heat exchanger (51) feeds to indoor, the moisture that spins off from second adsorption heat exchanger (52) is arranged to outdoor with second air.On the other hand, if be in the humidification running, second air that then has been carried out humidification in second adsorption heat exchanger (52) feeds to indoor, and first air row that moisture has been absorbed by first adsorption heat exchanger (51) is to outdoor.
-expansion valve control action-
[0051] below, control describes about the aperture of the expansion valve (55) in the above-mentioned humidity control apparatus (10).
[0052] as mentioned above, because above-mentioned humidity control apparatus (10) utilizes running controller (31) to switch between running of first state and the running of second state every three minutes, so at first opening controller (32) is beginning from each state running to carry out control 1 till having passed through the valve control T zero hour that was arrived in 168 seconds state running being switched the back in principle, the aperture of expansion valve (55) is controlled at fixedly aperture.And opening controller (32) is controlled the aperture of expansion valve (55) once carrying out control 2 through the valve control T zero hour in the time of promptly 168 seconds, so that the refrigerant superheat degree becomes promptly 5 ℃ of settings.
[0053] just because the running of each state switches with the short time, so in each state running when the refrigerant superheat degree reach stable before, the state running is just switched.Therefore, above-mentioned opening controller (32) is controlled expansion valve (55) when each state running soon finishes in principle, so that the degree of superheat becomes setting.Turn round according to each state and to carry out this control action.
[0054] secondly, because be necessary to stipulate the fixedly aperture of above-mentioned opening controller (32), so initial setting device (33) is set the fixedly aperture of opening controller (32).The aperture of the expansion valve (55) of this initial setting device (33) when first state when beginning running is set at the aperture of expansion valve (55) last first state running and finishes, the aperture of the expansion valve (55) when when above-mentioned second state running beginning, the aperture of expansion valve (55) being set at last second state running and finishing.
[0055] just, in running of first state and the running of second state, the equal reason of loss of air pressur owing to the pressure loss of the loop direction difference of cold-producing medium, cold-producing medium in the different and air flue causes the aperture of expansion valve (55) also different.Therefore, when the running of beginning first state, the aperture of the expansion valve (55) of first state running of continuation maintenance last time, when beginning second state turns round, the aperture of the expansion valve (55) of second state running that the continuation maintenance is last.
[0056] on the other hand, before the valve control T zero hour of above-mentioned each state running process, when opening controller (32) is controlled at the fixedly following time of state of aperture with the aperture of expansion valve (55), if the refrigerant superheat degree is lower than desired value, then aperture reduces the aperture that device (35) reduces expansion valve (55).
[0057] also has, before the valve control T zero hour of above-mentioned each state running process, when opening controller (32) is controlled at the fixedly following time of state of aperture with the aperture of expansion valve (55), if As time goes on the refrigerant superheat degree increases to the degree of superheat of defined when above, then the aperture of aperture enhancer (36) increase expansion valve (55).
[0058] just, start above-mentioned compressor (53) and begin to dehumidify after running or the humidification running, need the time of defined till the fixedly aperture of the opening controller (32) that sets to initial setting device (33) reaches and stablizes.Specifically, after each state running was switched, the refrigerant superheat degree rose sometimes significantly, descends suddenly sometimes.Therefore, utilize aperture to reduce device (35) and aperture enhancer (36) comes the aperture of expansion valve (55) is controlled.
[0059] thereafter, the control that utilizes above-mentioned aperture to reduce device (35) and aperture enhancer (36) changes the control aperture of opening controller (32), thereby the aperture of expansion valve (55) reaches stable.
[0060] for example, in case carry out the control of above-mentioned expansion valve (55) repeatedly, then the aperture of expansion valve (55) reaches stable, and shown in M and N among Fig. 4, after each state running is switched, fall after rise after the refrigerant superheat degree rises rapidly, before each state running is switched, become the degree of superheat of defined.
[0061] also have, when the volume change of above-mentioned compressor (53), retriever (34) carries out revisal to the control aperture of opening controller (32), makes that the aperture of expansion valve (55) is corresponding with the volume change of compressor (53).
[0062] also have, when the aperture of the expansion valve (55) when each state running of last time finishes did not exist, the aperture of the expansion valve (55) when above-mentioned initial setting device (33) finishes other state runnings was set at the initial stage aperture.
The effect of-embodiment-
[0063] as mentioned above, according to present embodiment,, just the aperture of expansion valve (55) is controlled owing to controlling the zero hour through valve from each state running beginning back one, make the refrigerant superheat degree become setting, so can control the aperture of expansion valve (55) more stablely.Just, owing to each state running was switched with the short time, so the refrigerant superheat degree change significantly occurs in each state running.So, when the approaching end of each state running, the aperture of expansion valve (55) is controlled, make the refrigerant superheat degree become setting, therefore can carry out stable control to the aperture of expansion valve (55).
[0064] also have, from above-mentioned each state running begin to valve control zero hour through till the aperture of expansion valve (55) is remained definite value, so can realize the stabilisation of expansion valve (55) aperture control.
[0065] also has, the valve control T zero hour of above-mentioned each state running through before, when the refrigerant superheat degree than desired value hour, then reduced the aperture of expansion valve (55), so can prevent so-called wet running, and can prevent that liquid refrigerant from turning back in the compressor (53).
[0066] also has, before the valve control T zero hour of above-mentioned each state running process, when As time goes on the refrigerant superheat degree increases to the degree of superheat of defined when above, then increased the aperture of expansion valve (55), so can prevent the overheated of compressor (53) really.
[0067] also has, because the aperture of the expansion valve (55) when when above-mentioned first state running beginning, the aperture of expansion valve (55) being set at last first state running and finishing, the aperture of the expansion valve (55) when when above-mentioned second state running beginning aperture of expansion valve (55) being set at last second state running and finishing is so can make the aperture of expansion valve (55) promptly converge to setting.
[0068] just, in running of first state and the running of second state, the equal reason of loss of air pressur owing to the pressure loss of the loop direction difference of cold-producing medium, cold-producing medium in the different and air flue causes the aperture of expansion valve (55) also different.Therefore, by when beginning first state turns round, continue the aperture of the expansion valve (55) of last first state running of maintenance, when the running of beginning second state, continue the aperture of the expansion valve (55) of last second state running of maintenance, thereby the aperture of expansion valve (55) is restrained.
[0069] also has, when the volume change of above-mentioned compressor (53), carry out revisal and make that the aperture of expansion valve (55) is corresponding with the volume change of compressor (53), so the aperture control of expansion valve (55) can be become the aperture that is suitable for operating condition, and can realize the stabilisation of expansion valve (55) aperture.
[0070] also has, when the aperture of the expansion valve (55) when each state running of last time finishes does not exist, the aperture of the expansion valve (55) when other state runnings are finished is set at the initial stage aperture, so the aperture of expansion valve (55) can be set for aperture, and the aperture of expansion valve (55) is promptly restrained near operating condition.
