Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present inventionCase is clearly and completely described, and obviously, described embodiment is only one of the present inventionDivide embodiment, instead of whole embodiment. Based on the embodiment in the present invention, this area is generalLogical technical staff is not making the every other embodiment obtaining under creative work prerequisite,All belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of air-conditioning system, as shown in Figure 1, comprise indoor set 10,Off-premises station 11 and controller, wherein, described off-premises station 11 comprises: compressor 111, condenser112, for improving first blower fan 113 of heat exchange efficiency of described condenser 112; Described indoorMachine 10 comprises: the first evaporimeter 101, the second evaporimeter 102, steam for improving described firstThe second blower fan 103 of the heat exchange efficiency of hair device 101, for improving described the second evaporimeter 102The 3rd blower fan 104 of heat exchange efficiency, first throttle element 105; Described the first evaporimeter 101Heat exchange area is greater than the heat exchange area of described the second evaporimeter 102.
Between the exhaust outlet of described compressor 111 and air inlet, be connected successively described condenser 112, instituteState the first evaporimeter 101, described first throttle element 105 and described the second evaporimeter 102; InstituteState controller respectively with described the first blower fan 113, described the second blower fan 103, described the 3rd blower fan104 are connected with described first throttle element 105.
Described controller, for controlling rotating speed and described second blower fan of described the first blower fan 113103 rotating speed, makes described the first evaporimeter 101 realize heat-production functions.
Wherein, the rotating speed of described the first blower fan 113 is less than the rotating speed of described the second blower fan 103.
Described controller, also for controlling rotating speed and the described first segment of described the 3rd blower fan 104The aperture of fluid element 105, makes described the second evaporimeter 102 realize dehumidification function.
Concrete, the rotating speed of controller control the first blower fan 113, makes changing of condenser 112The thermal efficiency is lower, and the refrigerant liquid of the higher temperature of condenser 121 flows into the first evaporimeterIn 101, because the temperature of the refrigerant liquid of the higher temperature of condenser 121 is necessarily greater than indoorThe temperature of air, and the rotating speed of controller control the first blower fan 113 is less than second blower fan 103Rotating speed, illustrates that the heat exchange efficiency of condenser 112 is less than the heat exchange efficiency of the first evaporimeter 101,So now the first evaporimeter 101 heats room air, has realized heat-production functions.
In addition, the aperture of controller control first throttle element 105, from first throttle elementThe liquid that 105 cold-producing mediums that flow out are low-temp low-pressure, what flow into the second evaporimeter 102 is also low temperatureThe refrigerant liquid of low pressure, now, the rotating speed of controller control the 3rd blower fan 104 controlsThe heat exchange efficiency of two evaporimeters 102, when the heat exchange efficiency of needs the second evaporimeter 102 higherTime, the rotating speed of controlling the 3rd blower fan 104 is larger, such the second evaporimeter 102 go out wind-warm syndromeSpend lower, thereby make indoor steam meet the cold droplet that becomes, from the second evaporimeter 102Discharge outlet discharge, realized dehumidifying, as the above analysis, the first evaporimeter 101 is rightRoom air heats, and the second evaporimeter 102 is that room air is dehumidified, and dehumidifiesTime must be accompanied by refrigeration, first room air heats, and then cooling, due to theThe heat exchange area of one evaporimeter 101 is greater than the heat exchange area of the second evaporimeter 102, illustratesThe degree that one evaporimeter 101 heats room air is greater than the second evaporimeter 102 to indoorThe degree that air is lowered the temperature, so generally, is that room air is heated, therebyRealize not cool-down dehumidification.
It should be noted that, in this air-conditioning system, controller can be integrated in indoor set or outdoorOn machine, also can arrange separately.
It should be noted that, the aperture that controller control first throttle element 105 is opened can rootThe traffic demand of border cold-producing medium and determining factually; Controller control the first blower fan 113, the second blower fan 103With the rotating speed of the 3rd blower fan 104 be also according to the actual requirements self adaptation adjust.
The embodiment of the present invention provides a kind of air-conditioning system, comprising: indoor set, off-premises station and controlDevice, wherein, off-premises station comprises: compressor, condenser and the first blower fan, indoor set comprises:The first evaporimeter, the second evaporimeter, the second blower fan, the 3rd blower fan and first throttle element, controlThe rotating speed of device control the first blower fan processed and the rotating speed of the second blower fan, make the first evaporimeter realize systemHot merit energy, the rotating speed of controller control the 3rd blower fan and the aperture of first throttle element, makeTwo evaporimeters are realized dehumidification function. Like this, because the rotating speed of the first blower fan is less than second blower fanRotating speed, illustrates that the heat exchange efficiency of condenser is less than the heat exchange efficiency of the first evaporimeter, so energyEnough make the first evaporimeter high to the degree of indoor temperature heating, changing due to the first evaporimeter againThe long-pending heat exchange area that is greater than the second evaporimeter of hot side, illustrates that the first evaporimeter adds indoor temperatureThe degree of heat is greater than the degree of the second evaporimeter to indoor temperature refrigeration, thereby makes the first evaporationThe combination of device and the second evaporimeter, makes the current indoor temperature can be lower than original indoor temperature,And because the second evaporimeter can freeze to indoor temperature, the leaving air temp of the second evaporimeter is describedLower, make the steam of room air meet the cold droplet that becomes, thereby realized dehumidifying, combineUpper, air-conditioning system provided by the invention has realized the not effect of cool-down dehumidification, is applicable to only dehumidifyingThe environment of not lowering the temperature.
