Abstract
The invention discloses a device for improving dehumidification ability in summer through ceiling radiation. The device is mainly composed of a ceiling radiation end system, an air exhaust and fresh air heat exchange system and a fresh air unit system, and comprises the following main equipment including a hot pump unit, a circulating water pump, a ceiling radiation end, a heat exchanger, an exhaust fan, an air feeder and a fresh air unit heat exchanger. The method comprises the following step: respectively carrying out heat exchange on the outdoor fresh air and indoor exhaust air, and then on the outdoor fresh air and the fresh air processed by an air exhaust and the fresh air unit, cooling the fresh air through a first heat exchanger; cooling and dehumidifying the fresh air in a second heat exchanger; carrying out heat exchange on the dehumidified fresh air and the fresh air from the heat exchanger; heating the fresh air; and finally feeding the fresh air into a room, so that the dehumidification ability of the fresh air unit is improved. The device and the method have the characteristics of being simple in structure and convenient to operate, and saving the energy and the like; and the device is suitable for occasions in which the dehumidification ability needs to be improved in summer through ceiling radiation.
Description
Technical field
The present invention relates to a kind of apparatus and method improving ceiling radiation dehumidifying effect in summer of HV&AC engineering technical field.
Background technology
Along with the development of society, people have very urgent requirement to building energy conservation.And the raising day by day of living standard along with people, better requirement be there has also been to the environment of the indoor that oneself is lived, so ceiling radiation air-conditioner is little with its operation noise, energy-conservation, the advantage that comfortableness is high, enter our life rapidly, but, in order to meet the demand of user to fresh air, and solve room air in refrigeration situation, likely on the ceiling and the condensation situation that floor occurs, in order to thoroughly control the humiture of room air, the fresh air conditioner treatment system that this system increases, dehumidification treatments is carried out to room air, to reach instructions for use.
In the winter time, ceiling radiant heating cooling system has no special requirements to air, mainly consider the demand of user to air, therefore gravity-flow ventilation and replacement aeration all can use.But in summer, particularly the relative air humidity feature of some day of Beijing is large, its dew-point temperature even reaches 24-25 DEG C, be much higher than the operating temperature of ceiling radiant heating cooling system, although this weather occurs that chance is few, number of days is not long, but its shortcoming is apparent, very likely there is the phenomenon as the ceiling that a lot of cold emission tops system occurred drips, and this system more may there is upper-layer user floor on there is situation about condensing, so outdoor air can not be used completely to come indoor inletting fresh air, drying process must be carried out to air, to make its dew-point temperature lower than the temperature of ceiling.
Summary of the invention
Technical problem: the present invention is directed to the deficiencies in the prior art, develop a kind of device improving ceiling radiation dehumidifying effect in summer, first and the indoor exhaust wind heat exchange by new for outdoor wind, again by the first Fresh air handling units, reduce its temperature, then enter the second Fresh air handling units to dehumidify, finally send into room, thus improve the dehumidifying effect of Fresh air handling units.
Technical scheme: a kind of device improving ceiling radiation dehumidifying effect in summer that the present invention announces, is characterized in that this device comprises air draft and new wind-heat exchange system, VMC and ceiling radiating system.In air draft and new wind-heat exchange system, the input termination indoor exhaust wind pipeline of exhaust blower, a end of the output termination heat exchanger of exhaust blower, the b end of heat exchanger leads to outdoor; In VMC, the outdoor fresh air pipeline of input termination of pressure fan, the c end of the output termination heat exchanger of pressure fan, the a end of the d termination heat exchanger of heat exchanger, the input of the b termination heat exchanger of heat exchanger, the input of the output termination heat exchanger of heat exchanger, the c end of the output heat exchanger of heat exchanger, the d end of heat exchanger leads to indoor by pipeline; In ceiling radiating system, the input of the output termination radiation tail end of source pump, the input of the output termination water circulating pump of radiation tail end, recirculated water delivery side of pump connects the input of source pump.
The feature of this device is also, by new for outdoor wind successively respectively with indoor exhaust wind and Fresh air handling units process after new wind carry out heat exchange, pass through First Heat Exchanger again, reduce its temperature, then enter the second heat exchanger and carry out cool-down dehumidification, the new wind after dehumidifying carries out heat exchange with heat exchanger new wind out again, improves its temperature, finally send into room, thus improve the dehumidifying effect of Fresh air handling units.
In this device, heat exchanger and heat exchanger can be double pipe heat exchangers, also can be plate type heat exchangers, also can be other type heat transmission equipments; Source pump also can be absorption chiller, also can be that the cold water of other type produces unit.
Beneficial effect:
1, the present invention has added two heat exchangers and a Fresh air handling units on original ceiling Radial Basis, by new for outdoor wind successively respectively with indoor exhaust wind and Fresh air handling units process after new wind carry out heat exchange, pass through First Heat Exchanger again, reduce its temperature, then enter the second heat exchanger and carry out cool-down dehumidification, the new wind after dehumidifying carries out heat exchange with heat exchanger new wind out again, improve its temperature, finally send into room, structure is simple, easy to operate.
2, the present invention makes full use of the temperature of indoor exhaust wind, reduces new air temperature, thus improves the dehumidifying effect of Fresh air handling units, economize energy.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further elaborated.
Fig. 1 is a kind of schematic diagram improving the apparatus and method of ceiling radiation dehumidifying effect in summer of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of device improving ceiling radiation dehumidifying effect in summer that the present invention announces, is characterized in that this device comprises air draft and new wind-heat exchange system, VMC and ceiling radiating system.In air draft and new wind-heat exchange system, the input termination indoor exhaust wind pipeline of exhaust blower 1, a end of the output termination heat exchanger 2 of exhaust blower 1, the b end of heat exchanger 2 leads to outdoor; In VMC, the outdoor fresh air pipeline of input termination of pressure fan 3, the c end of the output termination heat exchanger 2 of pressure fan 3, the a end of the d termination heat exchanger 6 of heat exchanger 2, the input of the b termination heat exchanger 4 of heat exchanger 6, the input of the output termination heat exchanger 5 of heat exchanger 4, the c end of the output heat exchanger 6 of heat exchanger 5, the d end of heat exchanger 6 leads to indoor by pipeline; In ceiling radiating system, the input of the output termination radiation tail end 9 of source pump 7, the input of the output termination water circulating pump 8 of radiation tail end 9, the input of the output termination source pump 7 of water circulating pump 8.
