Description
Technical field
The utility model relates to a kind of novel air interchanger, and this device is applied to the outer Cryogenic air of suction chamber to keep the indoor low temperature environment.
Background technology
Along with the application of the mobile communication and the network information technology, the server apparatus of various communication base stations and information centre needs the environment of a relative low temperature, can normally move for a long time with assurance equipment.Normally dispose the single cold type air-conditioner in machine room and the base station, with strictness control indoor environment temperature.
For existing air-conditioner, renew wind mechanism for improving the ambient air quality of using air-conditioner, disposing usually.As the patent formerly of following content disclosed, the patent No. is 200410063568, name is called aircondition, its scheme is that described aircondition adopts an air interchanger, this air interchanger is by a shared air inlet and exhaust piper, the form that promptly adopts sleeve pipe is from the inside and outside fan of both ends junction chamber, and the use motor-driven is put or is expelled in the tracheae so that gas is inhaled.
The ventilation mechanism of above-mentioned existing aircondition is to carry out cross-ventilation to improve IAQ in compressor operating.If the compressor wind that then renews out of service promptly stops, otherwise above-mentioned ventilation mechanism will directly cause the variation of indoor temperature, thereby be inapplicable for the place that indoor temperature has higher requirements.And, when the outdoor environment temperature in winter is low, carry out refrigerating operaton if still start compressor ventilation the time, obviously can waste energy, improve the operation cost in above-mentioned place.
The utility model content
Low-temperature aeration air interchanger described in the utility model, its purpose of design are to address the above problem with deficiency provides a kind of by the inside and outside temperature difference of sensing chamber, and automatic compound ventilation air-changing device from outdoor suction Cryogenic air.This device can be kept indoor design temperature by direct suction chamber outer air, thereby be need not by other equipment under the lower prerequisite of outdoor temperature through the body of wall of chamber between using, and energy savings.
For realizing above-mentioned purpose of design, the primary structure of described low-temperature aeration air interchanger comprises:
One housing, this housing has top board, side plate and base plate;
One fresh air inlet is set on the front side board of housing,, connects a blast pipe in the air intake barrel forward end at fresh air inlet arranged outside one air intake sleeve;
At enclosure interior, fresh air inlet rear side one screen pack is set, screen pack is fixed in the U type groove of housing base plate and top board;
Be provided with one by motor-driven blower fan at enclosure interior, screen pack rear side, blower fan is fixedly connected on the fixed head perpendicular to base plate, and fan outlet can embed in the vent of housing back side panel;
To the air flow circuit of housing fresh air inlet, an outdoor temperature sensor that is used to detect outside air temperature is set at the mouth of pipe of blast pipe;
In hull outside, an indoor temperature transmitter that is used to detect indoor air temperature is set;
Described indoor and outdoor temperature sensor connects the master control borad that is arranged on the base plate respectively by holding wire.
As the low-temperature aeration air interchanger of above-mentioned structure, the temperature difference of coming the inside and outside environment of sensing chamber by indoor temperature transmitter and outdoor temperature sensor.
When outdoor temperature is not higher than indoor temperature, the air-conditioning equipment in the closable chamber then, this moment, the fan operation of low-temperature aeration air interchanger started, and directly from outdoor introducing Cryogenic air, guaranteed the normal operation of indoor equipment with the temperature of keeping indoor environment.
This moment, blower fan was opened operation, and at enclosure interior formation negative pressuren zone, then outdoor air enters in the housing via blast pipe, fresh air inlet, and screen pack can filter the outdoor air that sucks, clean air after the filtration is inhaled in the blower fan, is discharged into the indoor environment from vent at last.
Owing to only use fan operation, can keep the indoor low temperature environment by outdoor Cryogenic air, so than using comparatively energy savings of air-conditioning equipment.
For improving the precision that detects outside air temperature, described outdoor temperature sensor is arranged on a side of the close mouth of pipe of blast pipe.
For improving the precision that detects indoor air temperature, described indoor temperature transmitter is arranged on the place of the easiest perception indoor temperature of hull outside.
As containing than juicy in the outdoor air that sucks, be that humidity is bigger, then both can be to the low-temperature aeration air interchanger, also can produce the adverse effect of corrosion to indoor equipment, thereby further improve structure and be, to the air flow circuit of housing screen pack, an outside humidity sensor that is used for sensing chamber's outer air humidity is set at the mouth of pipe of blast pipe;
Described outside humidity sensor is arranged on a side of the close fresh air inlet of housing.
Fixed effect for the filtration wind that improves enclosure interior, to form the structure of relative spacing in enclosure interior by screen pack, the base plate of housing and top board are provided with fixedly U type groove, then screen pack is plugged in the described fixedly U type groove, screen pack dirty after, can pull out by the opening part of side plate and clean.
For preventing under the bigger weather condition of rainy day or humidity, there are rainwater or condensation to flow into the enclosure interior of described low-temperature aeration air interchanger from blast pipe, can be at mouth of pipe place socket one blast cap that Open Side Down of blast pipe.
And on master control borad, also have air-conditioning control line joint, can be by the open and close of the compatible air-conditioning of control line control and this device.
Content to sum up, the advantage and the beneficial effect of described low-temperature aeration air interchanger are:
1, described low-temperature aeration air interchanger, can be when outdoor temperature be lower than indoor design temperature, directly outdoor Cryogenic air is introduced indoorly, it is indoor that to renew wind directly effective, not only saves energy, but also can carry out the filtration, purification of air, the air quality of indoor environment is guaranteed.
2, adopt the shell structure of integral type, comparatively directly convenient at aspects such as installation, maintenance and change air circulation paths.
