Description
Technical field
The utility model relates to a kind of heat insulating construction, relates in particular to a kind of heat insulating construction that is used for the low temperature vav terminal.
Background technology
The low form vav terminal is to adapt to the cold air distribution technology to use the vav terminal equipment of developing under the more prevalent situation at home and abroad, is widely used in wind pushing temperature and is 4 ℃ ~ 10 ℃ air conditioning system with variable.Because the wind pushing temperature of low-temperature air conditioner system is low, carry the required air quantity of identical cold to reduce, therefore installed capacity and the air-supply airduct size of AHU (air conditioner unit) in the air-conditioning system equipment have been reduced, the required space that takies reduces thereupon, thereby makes it have advantages such as the initial cost of saving, reduction operating cost.In addition, adopt the building room of cold air distribution system, relative air humidity is lower, and comfortableness improves.
But correspondingly, one time the wind wind pushing temperature has reduced, it is big that the temperature difference of the wind and the vav terminal external space becomes, loss of refrigeration capacity in order to ensure a wind is as far as possible little, therefore, structure for vav terminal equipment is had higher requirement, traditional vav terminal, an its wind air inlet duct is that localized metallic directly is connected with the connected mode of air intake panel, the junction is in good heat conduction state, when 4 ℃ ~ 10 ℃ cold wind of sending here as AHU are flowed through whole vav terminal via a wind air inlet duct, one time wind can be hotly rapid from the metal junction of an air intake panel and a wind air inlet duct, make the temperature of a wind be improved, and the surface temperature of whole air intake panel and the vav terminal shell that is attached thereto can reduce, when the surface temperature of vav terminal was lower than the dew-point temperature of its environment of living in, condensation can appear in its surface, thereby influenced the normal use of vav terminal.So traditional vav terminal of wind air channel of employing and the direct connected mode of air intake panel localized metallic, when being used for the low temperature air conditioning system with variable, can cause the loss of refrigeration capacity of a wind to reach the vav terminal surface more greatly and condensation occur, like this, promptly waste energy and harm equipment etc.
The air-valve driving shaft of traditional in addition vav terminal is made of metal, the heat conductivility of metal is good, and the end that this driving links to each other with the air-valve valve block places in the wind air channel of low temperature, the other end of driving shaft places in the outer electric cabinet of vav terminal case, the temperature of this environment, humidity is higher relatively, therefore, place an end of the driving shaft in the electric cabinet condensation to occur because its temperature is lower than the dew-point temperature of environment of living in, and this part is connecting DDC control actuator, and the condensation on the valve shaft also may cause DDC control actuator in use to damage.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model proposes a kind of heat insulating construction that is used for the low temperature vav terminal.
The utility model is achieved by the following technical programs: the heat insulating construction that is used for the low temperature vav terminal includes adiabatic Connection Block, adiabatic seal, cryogenic system air-valve drive rod assembly, a wind wind inlet channel of described low temperature vav terminal is connected by at least one adiabatic Connection Block with the air intake panel, and wind wind inlet channel is pressed with near the place with the air intake panel and makes it not the groove that can have metal directly to contact with the air intake panel, and fill up gap between wind wind inlet channel groove and air intake panel with adiabatic seal in when assembling, described cryogenic system is connected with air-valve with the air-valve drive rod assembly, cryogenic system is plugged into by cryogenic system air-valve driving shaft with the air-valve drive rod assembly in the inner chamber of adiabatic axle sleeve and constitutes, the inner chamber axial cross section of adiabatic axle sleeve is a noncircular cross section, and the function that prevents valve shaft and its generation relative motion is arranged.
Further measure is: a described wind wind inlet channel is connected respectively by screw by at least one adiabatic Connection Block with the air intake panel, and described adiabatic axle sleeve and adiabatic Connection Block are made of adiabatic plastic material.
The effect that the utility model is useful is: the heat insulating construction of this vav terminal is applicable to various low temperature vav terminals or similar air conditioner end equipment, insulation is carried out in position connection to temperature difference maximum in the low temperature vav terminal, be respectively to take adiabatic the connection between wind inlet channel and the air intake panel, cryogenic system places the adiabatic sheath of the interior end socket of electric cabinet with the air-valve drive rod assembly, purpose is that above-mentioned position heat transfer effect is weakened, thus make the vav terminal outside not the loss of refrigeration capacity of dewfall and a wind reduce, DDC control actuator can be in the normal working environment and move.
