Ventilation system of air conditioning room

Abstract

The invention discloses a ventilation system of an air conditioning room, comprising a box used for communicating the inside with the outside of the air conditioning room. An air discharging-feeding port and a fresh air outlet are arranged on the inner side of the room of the box, an air discharging port and a fresh air inlet are arranged on the outer side of the room of the box, a heat exchanging plate is arranged in the box and divides an inner cavity of the box into two air channels, wherein one air channel is an air discharging channel consisting of the air discharging-feeding port, the box, the heat exchanging plate and the air discharging port, the other air channel is a fresh air channel consisting of the fresh air inlet, the box, the heating exchanging plate and the fresh air outlet, and the air discharging port is communicated with an air inlet of an outdoor unit of an air conditioner. In the invention, the power for the flowing of air in the air channels is provided by the rotation of a fan of the outdoor unit of the air conditioner, so that the natural circulation of air discharging and fresh air introduction for the air conditioning room, and extra electric energy doesnot need to be consumed; and simultaneously, the discharged air and the fresh air are subjected to heat exchange by the heat exchanging plate, so that the recycling of the energy of the discharged air can be realized.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a ventilation system for an air-conditioned room. Background technique [0002] With the improvement of living standards and the deterioration of the external environment, people spend more and more time in air-conditioned rooms. In order to minimize the external heat loss of air-conditioned rooms, the airtightness requirements of the rooms are constantly improving, but in the room While the temperature of the building is lowered, the fresh air entering the room is decreasing, so the so-called "sick building syndrome" is formed due to the lack of fresh air, which gradually affects people's physical and mental health. [0003] In order to improve the indoor air quality, fresh air must be introduced into the room. At present, there are two main forms: one is to directly open the window to let in fresh air, and use the window to discharge the indoor air, which will increase the load of the ...

Problems solved by technology

For example, the patent document with the notification number CN201476212U discloses a passive energy-saving fresh air system with H-shaped belt storage. Although this system can introduce fresh air into the room without consuming energy, it is only suitable for rooms without air conditioning or It is the ventilation of the transition season, because it neither processes the incoming fresh air nor recovers the energy of the exhausted wind

The patent document with the notification number CN201297735Y discloses a ventilation device with a heat recovery function. Although the device can recycle the energy of the exhaust air when the fresh air is introduced into the room, the air inlet channel and the exhaust air in the device The channels are separated by nano-microporous heat exchange membranes made of polymer materials. Harmful gas molecules in the exhaust air may enter the fresh air during heat exchange with the fresh air and be sent into the room again, which cannot achieve improvement. The purpose of indoor air quality. In addition, the device must use a fan to supply air during operation, which consumes extra power and cannot achieve the purpose of energy saving.
