Distributed energy-saving cold/hot ventilating unit

Abstract

The invention discloses an air conditioning unit and in particular relates to a distributed energy-saving cold / hot ventilating unit. The structure is as follows: an air inlet is formed on a fresh air upper header; the lower end of the fresh air upper header is connected with a fresh air short pipe and an air exhaust upper header; the lower end of the fresh air short pipe is connected with a fresh air lower header; a fresh air inlet is formed on the fresh air lower header; the lower end of the air exhaust upper header is connected with an air exhaust lower header through an air exhaust connecting short pipe; an exhaust fan is arranged in the air exhaust upper header; an exhaust pipe is arranged above the exhaust fan; a blower is arranged in a hollow cavity formed by the fresh air lower header and the air exhaust lower header; an air outlet is formed on the air exhaust lower header; the lower end of the hollow cavity is connected with a coil pipe heating cooler; the lower end of the coil pipe heating cooler is connected with a centrifugal dehydrator; the lower end of the centrifugal dehydrator is connected with an adjustable air supply outlet; and a condensing water pipe is arranged on the adjustable air supply outlet. The ventilating unit is suitable for large factory buildings, has a good heating or cooling effect, is energy-saving and low in construction cost, does not influence the production process and has long service life.

Description

technical field [0001] The invention relates to an air conditioning unit, in particular to a decentralized energy-saving heating and cooling ventilation unit. Background technique [0002] Heating in winter and cooling in summer for tall factories in the alpine regions of northern my country, including large public buildings and large spaces, have always been difficult to solve. Centralized air-conditioning systems, radiant heating systems, and heaters were used in the past and are still used. Although they have certain effects, due to thermal pressure, strong natural convection occurs in the tall building space, forming a vertical temperature gradient, resulting in a large amount of heat. Reactive loss. In this case, no matter how many heat dissipation or refrigeration equipment are installed in the lower working area, it will not help, and the requirements for heating or air conditioning cannot be met. Simultaneously, because cost is expensive, volume is big, use inconve...

Problems solved by technology

In this case, no matter how much heat dissipation or refrigeration equipment is installed in the lower working area, it will not help, and it still cannot meet the requirements of heating or air conditioning

At the same time, due to the high cost, large volume, inconvenient use or affecting the production process, etc., its cost performance is greatly reduced and is not popular.
