Description

Intelligent energy-saving central air-conditioning device

technical field

The utility model relates to the technical field of central air-conditioning, in particular to an intelligent energy-saving central air-conditioning device.

Background technique

Nowadays, people are increasingly relying on air conditioners to obtain a comfortable ambient temperature, but most of the air conditioners do not have a ventilation device. For the sake of energy saving, when the air conditioner is working, the windows are closed. After a long time, the indoor carbon dioxide content rises, the oxygen content drops, and the air is dirty. For this reason, most of the central air conditioners have added a ventilation device, which sucks fresh air from the outside, and sends it into the room after temperature and humidity adjustment; and discharges a part of the indoor air to the outside to maintain indoor and outdoor air exchange.

After adding the ventilation device, although the indoor air can be kept fresh, it is necessary to add fresh air fans and exhaust fans, which increases the power consumption, and because the temperature of the fresh air from the outside must be adjusted continuously to the indoor temperature, it also greatly increases the cost of the air conditioner. The workload is not conducive to energy saving.

In order to solve the above technical problems, the technical solution of the utility model is: an intelligent energy-saving central air-conditioning device, including an air-conditioning heat exchange main unit, an air outlet is provided on the air-conditioning heat exchange main unit, and the air-conditioning heat exchange main unit communicates with the indoor air suction port , the indoor air suction port is provided with a suction fan; a new fan, the new fan communicates with the air-conditioning heat exchange host through a fresh air channel; an exhaust fan, the exhaust fan communicates with the outside through an exhaust channel;

The intelligent energy-saving central air-conditioning device also includes a control unit, the control unit includes a controller and a carbon dioxide sensor installed indoors, the signal line of the carbon dioxide sensor is connected to the input end of the controller, and the controller's The output ends are respectively connected with the fresh air fan and the exhaust fan.

As a preferred technical solution, the control unit also includes a temperature sensor installed indoors, the signal line of the temperature sensor is connected to the input end of the controller; the output end of the controller is respectively connected to the suction The fan is connected to the air conditioner heat exchange host.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

1. Since the utility model is provided with a control unit, the control unit includes a controller and a carbon dioxide sensor located in the room, the signal line of the carbon dioxide sensor is connected to the input end of the controller, and the output end of the controller is connected to the fresh air fan and the exhaust fan respectively. Therefore, set the upper and lower limits of the indoor carbon dioxide concentration. When the carbon dioxide sensor detects that the carbon dioxide concentration is higher than the upper limit, the controller will turn on the fresh air fan and exhaust fan synchronously to make the indoor air ventilated. When the indoor carbon dioxide concentration is lower than the lower limit , the controller synchronously turns off the fresh fan and the exhaust fan, and stops ventilation. At this time, the air conditioner only sucks air from the room. The utility model takes the carbon dioxide concentration as the standard, can effectively control the ventilation, keeps the indoor air fresh, and can well realize the energy-saving effect.

2. Since the control unit also includes a temperature sensor located in the room, its signal line is connected to the input end of the controller, and the output end of the controller is also respectively connected to the suction fan and the heat exchange host of the air conditioner. Therefore, in winter, set the upper and lower limits of the indoor temperature. When the temperature sensor detects that the temperature value is lower than the lower limit, the controller will turn on the suction fan and the heat exchange host of the air conditioner to heat the air to make it reach the set temperature range. When the temperature value is higher than the upper limit, the controller turns off the suction fan and the heat exchange host of the air conditioner to realize energy-saving control; Make it reach the set temperature range, when it detects that the temperature value is lower than the lower limit, the controller turns off the suction fan and the heat exchange host of the air conditioner to realize energy-saving control.
