Description of drawings
Fig. 1 is the system layout figure of the utility model;
Fig. 2 is the control principle figure of the utility model;
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
A kind of transformer room and master-control room machine room overall intelligence temperature control energy conserving system; Show like Fig. 1 and Fig. 2; By being installed on the battery compartment battery is carried out thermostatically controlled insulating box air-conditioning, is installed in outside the transformer room transformer room is carried out thermoregulator intelligent heat exchange VMC, is installed in the master-control room master-control room is carried out the intelligent natural wind VMC of natural wind adjusting and master-control room is carried out thermoregulator air conditioner in machine room constituting; Insulating box air-conditioning, intelligent heat exchange VMC, intelligent natural wind VMC and air conditioner in machine room link together through controller, each several part is carried out temperature detection and realized the transformer room and the control of the overall intelligence temperature of master-control room machine room by controller.Describe respectively in the face of each part down:
The insulating box air-conditioning is realized the temperature control function to battery compartment.Because the battery in the battery compartment is the harshest to temperature requirement, therefore, adopt the insulating box air-conditioning separately battery to be carried out (temperature range 15-25 ℃ of temperature control; Temperature is too low can to reduce accumulator capacity, and Tai Gao can shorten battery service life again greatly), temperature sensor is installed in battery compartment; Can detect the temperature in the battery compartment through temperature sensor; When temperature rises to setting maximum temperature (as: 25 ℃ can be passed through menu setting), start the insulating box air-conditioning; Reduce to insulating box when detected temperature and set (as: 20 ℃ of minimum temperatures; Can pass through menu setting) time, close the insulating box air-conditioning, setting about maximum temperature to realize the temperature maintenance in the insulating box.
Intelligence heat exchange VMC carries out adjustment to the transformer room, and this system comprises heat exchange body core, indoor blower fan, outside blower fan, metal coating shell, air supply duct, control assembly and indoor and outdoor temperature detector etc.Intelligence heat exchange VMC adopts isolated heat exchange mode; Can new wind outside the transformer room be taken away transformer room's internal heat as low-temperature receiver; Transformer room's outer air does not directly get in the transformer room, is sent back to indoor after the transformer room air cools off through heat exchange again.Its operation principle is: utilize indoor/outdoor temperature-difference to carry out the gas heat exchange of indoor and outdoor both sides, thereby reduce indoor temperature; See from the angle of outside, outdoor air under the effect of outside blower fan from the outside air outlet access to plant body, carry out heat exchange through heat exchange core body then, exhaust outlet is discharged to outdoor again from the outside; See that from the angle of indoor room air by indoor ajutage access to plant body, carries out heat exchange through heat exchange core body then under the effect of indoor blower fan, come back in the machine room by the indoor backwind tube again.
Intelligent natural wind VMC (natural cooling air cabinet) carries out adjustment to the master-control room machine room; This system comprises filtration fraction, centrifugal blower, control system and structure rack, and whole unit has the complete control system of a cover, can realize the control function to mechanical part and electric elements; And accurately monitor temperature, the humidity of air in the master-control room machine room; And the flow of new wind, during installation, only need to connect simple electric wiring and airduct (if needed); And on body of wall, open two inlet and outlets of cooling usefulness naturally, can normally move.The operation principle of intelligent natural wind VMC is: this system configuration the natural cooling system of standard; As master-control room outdoor temperature ST2<indoor temperature ST1 more than 2 ℃; And indoor temperature ST1 >=design temperature and when reaching the response time, pressure fan starts, and utilizes the outdoor cold wind of master-control room to carry out the nature cooling; Significantly reduce the compressor operating time, thereby reach obvious energy saving effect; When outside humidity >=control point (acquiescence 85%), pressure fan cuts out; During wind pushing temperature<10 ℃ (can set), the air-valve actuator is opened; During wind pushing temperature >=10 ℃ (can set), the air-valve actuator is closed.
The utility model to transformer room and master-control room building environment control principle is: main control is provided with transformer room and the whole operational factor of master-control room machine room; These parameters comprise that outdoor low temperature thresholding (T1), outdoor high temperature thresholding (T2), indoor temperature T3, outside humidity S1, indoor humidity S2 and other are provided with parameter and item; The real-time sensing chamber of controller internal and external temperature, humidity, dirt degree; Automatically the reasonable work of control blower fan and air conditioner in machine room selects to start blower fan or air conditioner in machine room cooling, sets (as: 35 ℃ of maximum temperatures when temperature rises to the master-control room machine room; Can pass through menu setting) time, controller control VMC or air conditioner in machine room start; When detected temperature is reduced to master-control room machine room setting minimum temperature (as: 32 ℃), close VMC or air conditioner in machine room, setting about maximum temperature to realize the temperature maintenance in the master-control room machine room, avoid the frequent start-stop of master-control room air conditioner in machine room simultaneously.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the specific embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
