Efficient heat-exchange fresh-air conditioning plant

Abstract

An efficient heat-exchange fresh-air conditioning plant comprises through-wall air supplying and exhausting tubes, fresh-air supplying channels, an indoor air returning and exhausting channel, an angle type fan coil unit and an indoor fresh-air outlet. The through-wall air supplying and exhausting tubes are arranged on two sides of a wall corner and are connected with air supplying and exhausting channel accesses. An air supplying channel comprises left and right triangular channels and transverse channels partitioned via transverse partition plates, and an exhausting channel comprises a middle triangular channel and transverse channels partitioned via transverse partition plates and transverse guide plates. Supplied air and exhausted air are transferred by metal partition plates via vertical channels and the transverse channels in a multi-pass reciprocating manner and are subjected to heat exchange mutually. After being subjected to heat exchange, fresh-air is delivered to a surface air cooler by the angle type fan coil unit to be subjected to heat exchange, then cooled hot air is delivered to an indoor air outlet, and the clean cooled hot air is supplied to the inside of a building. The fresh-air conditioning plant is novel in appearance, compact in structure, low in energy consumption and high in quality.

Description

technical field [0001] The invention relates to a fresh air air conditioner integrating fresh air replacement and fan coil units. Background technique [0002] Existing air-conditioning systems use indoor air for cooling and heating, making it difficult to ensure indoor air quality. Most of the existing fresh air systems are single-supply, single-row or simultaneous and intermittent supply and discharge. The air directly enters and exits the building, causing a large loss of indoor cooling and heat. Some fresh air replacement systems are not efficient, complex in structure, and expensive The cost is too high, it is a waste of space, it is very inconvenient to use, and it is noisy. There are holes in the walls and pipelines in the room, which is extremely unsightly. The present invention utilizes indoor right-angled corners, and the left, right, up, and down holes are concealed on both sides of the device. The supply and exhaust air from the upper supply and the lower retur...
