Detailed ways

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.

The following examples are non-limiting examples of the present invention.

Example 1:

As shown in Figures 1 and 2, the utility model machine room intelligent energy-saving ventilation system includes an air inlet channel 1 and an air outlet channel 3 arranged on the wall of the machine room, an air inlet device 2 arranged in the air inlet channel 1, an air outlet device arranged in the air outlet The air outlet device 4 in the channel 3, the indoor probe 5 that can detect the indoor temperature and humidity, the outdoor probe 6 that can detect the outdoor temperature and humidity, the air conditioner controller 7, and the main controller 13, the main controller 13 communicates with the incoming The wind device 2, the air outlet device 4, the indoor probe 5, the outdoor probe 6 and the air conditioner controller 7 in the machine room are connected through control lines.

In this embodiment, the main controller 13 uses a RISC single-chip microcomputer as the main control unit, and has a built-in Watchdog function protection system to prevent the program from running away. There is also an expansion slot in the main controller 13 as a spare digital and analog expansion interface. The indoor probe 5 and the outdoor probe 6 each use two temperature and humidity sensors to detect the indoor and outdoor temperature and humidity of the computer room.

As shown in Figure 2, the air inlet channel 1 is set on the wall on the shaded side of the machine room, and the distance between its vent and the ground is ≤1 meter. The distance from the roof is less than or equal to 1 meter. When the intelligent energy-saving ventilation system of the utility model is working, the outdoor cold air is drawn into the room through the air inlet device 2 in the air inlet channel 1, takes away the heat after passing through the heating equipment, and passes through the air The air outlet device 4 in the channel 3 is exhausted indoors to ensure that the hot air in the room is exchanged with the cold air outside.

FIG. 3 is a structural schematic diagram of the air inlet device 2 of the present invention. As shown in Figure 3, the air intake device 2 includes a housing 14, the housing 14 is an air duct, the housing 14 has a damper 10, an electric actuator 11, a fan 12, and the front end of the housing 10 also has a filter protection net 8 And filter dustproof net 9. Wherein the effect of filter protection screen 8 is to prevent bigger dirt such as mosquito from entering; Filter dust screen 9 adopts professional air filter screen, to guarantee efficient filtration. At the same time, both the filter protection net 8 and the filter dustproof net 9 are installed in an outer frame to facilitate regular disassembly, cleaning and repeated use, so as to ensure the cleanliness of the indoor air of the base station. The electric actuator 11 is a motion mechanism that controls the opening and closing of the damper 10. When the system is running, the damper 10 is opened by the electric actuator 11, and finally the fan 12 is turned on to exchange the indoor and outdoor air; when the ventilation system is closed, the fan 12 is first turned off , and then the damper 10 is closed by the electric actuator 11 to isolate the indoor and outdoor air.

The structure of the air outlet device 4 is similar to the air inlet device 2, because the dustproof filter is not needed when the wind is discharged, so the front end of the housing 14 only has the filter protection net 8, and the filter dustproof net 9 is not set.

When the ventilation system is running, the main controller 13 can collect temperature and humidity signals and display them after being processed by a single-chip microcomputer. When the temperature or humidity exceeds the set value, various controls, alarms and signal outputs can be completed. Specifically, the main controller 13 controls the air inlet device 2, the air outlet device 4 and the air conditioner according to the difference between the indoor and outdoor temperature and humidity by collecting the indoor and outdoor temperature and humidity values detected by the indoor probe 5 and the outdoor probe 6. The controller 7 is turned on and off to ensure that the computer room operates in a prescribed environmental state.

The working principle of the utility model ventilation system is as follows:

When the temperature sensor in the indoor probe 5 detects that the ambient temperature of the machine room is higher than the set temperature value for turning on the fan, at the same time the outdoor temperature is lower than the indoor temperature by a certain difference (this parameter can be set), and the outdoor temperature is guaranteed When the opening temperature is lower than the set value of the fan (this parameter can be set), and the indoor humidity or outdoor humidity is within the set humidity range, the ventilation system is turned on to cool down: first, the main controller 13 controls the electric actuator 11 to turn the damper 10 Open, then the main controller 13 starts the fan 12 to run, so that the air inside and outside the machine room is forced to exchange, and the temperature in the machine room is adjusted. When the indoor temperature drops below the set temperature value for turning off the fan, the ventilation system is turned off: first the main controller 13 turns off the fan 12 to run, and then the damper 10 is closed by the electric actuator 11 to prevent dust from entering. When the indoor and outdoor temperatures are above the set temperature value of turning on the fan, the method of cooling down by simple indoor and outdoor ventilation has failed. The controller 7 (the main controller 13 controls the air conditioner controller 7 by controlling the opening and closing of a relay), utilizes the air conditioner to cool down the machine room.

When the alternating current works normally, the utility model intelligent energy-saving ventilation system has the following four working states:

1. When the indoor temperature is lower than the high temperature setting value of the system, neither the ventilation system nor the air conditioner of the utility model will operate;

2. When the indoor temperature is higher than the high temperature setting value, the outdoor temperature is lower than the high temperature setting value, and the indoor or outdoor humidity is lower than the humidity setting value, the ventilation system will be turned on to cool down naturally. When the indoor temperature drops below the low temperature setting value , or when the indoor and outdoor temperature difference is within 2°C, turn off the fan in the ventilation system;

3. When the indoor temperature is higher than the high temperature setting value and the outdoor temperature is lower than the high temperature setting value, but the indoor and outdoor humidity are both higher than the humidity setting value, turn on the indoor air conditioner to cool down. When the indoor temperature is lower than the low temperature setting value , turn off the air conditioner;

4. When the indoor temperature and outdoor temperature are both higher than the high temperature setting value, turn on the air conditioner to cool down.

When the alternating current does not work normally, the ventilation system of the utility model has the following two working states:

1. When the indoor temperature is higher than the high temperature setting value, there is a temperature difference of 3°C between the outdoor temperature and the indoor temperature, and the indoor or outdoor humidity is lower than the humidity setting value, the ventilation system will be turned on to cool down naturally;

2. Turn off the fans in the ventilation system except for the above 1.
