Problems solved by technology

In the existing technology, the size of high-efficiency fans is larger than that of ordinary fans. Generally, considering the size of the machine room, most of the air handling units in buildings currently use small-sized and low-efficiency fans, which have the disadvantage of high energy consumption. Defects, and because of the large resistance loss at the connection between these small-sized low-efficiency fans and the air duct, it is necessary to increase the wind pressure of the fan.

Abstract

The invention relates to a height-adjustable vertical multi-fan combination high-efficiency air treatment unit, which is characterized in that it includes an air treatment section and a fan section, and the air treatment section is connected to the fan section through the unit height adjustment section to form a vertical height-adjustable connection structure The air treatment section includes the treatment section chassis and heat exchanger, condensate water pan, water inlet pipe, water outlet pipe and condensate water pipe. The side wall of the treatment section chassis is provided with an air inlet, and its bottom surface is provided with a water inlet and water outlet; the fan section includes The chassis of the fan section and several non-volute fans and motors are provided with an air outlet on the side wall of the fan section chassis; the height adjustment section of the unit adjusts the height of the unit so that the air outlet and the outlet pipe are connected without an elbow to realize the air outlet. Direct access to the ceiling of the air-conditioned room. The utility model has the beneficial effects of improving the fan efficiency of the air handling unit, reducing the resistance loss of the air duct, reducing the energy consumption of the fan, saving energy, reducing noise, and being convenient for installation and use.

Description

technical field [0001] The invention relates to an air handling unit, in particular to a highly vertical multi-fan combined high-efficiency air handling unit, which is suitable for a building heating air conditioning system. It belongs to the technical field of HVAC. Background technique [0002] At present, general public buildings are designed with corresponding HVAC systems, of which the air handling unit is an important part to provide the building interior with air treated by the HVAC system to meet indoor thermal comfort. Air transport needs to consume the power of the fan. In the case of the same air volume, the power consumed by the fan is related to the fan efficiency and wind pressure. higher. In the prior art, the size of high-efficiency fans is larger than that of ordinary fans. Generally, considering the area of ​​the machine room, small-sized and low-efficiency fans are generally used in the air handling units in most buildings. In addition, due to the large...
