Fan coil for air supply system of air conditioner

Abstract

The invention relates to the field of air conditioning system equipment, and discloses a fan coil for an air supply system of an air conditioner. The fan coil comprises a machine box, two fans drivenby a dual-axis motor are arranged on the side face of the machine box, the sides, away from the fans, of the machine box are communicated with air supply pipes, an installation box of a surface cooleris arranged inside the machine box, the surface cooler is installed between the inner walls of both sides of the installation box of the surface cooler, and the surface cooler is composed of a plurality of condensate ducts, fins and diversion plates. Under the high-end operation of the fans, high-speed air flow passes through channels between each fin and each diversion plate in the surface cooler, and the high-speed air flow is split, so that the high-speed air flow action between each fin and each diversion plate is average with the degree of turbulence formed after the condensate ducts, the degree of mutual interference in the overall space is low, and the air resistance after the high-speed air flow passes through the condensate ducts is effectively reduced, so that the velocity lossof the high-speed air flow is reduced, and the air supply efficiency and quality are improved.

Description

Technical field [0001] The invention relates to the field of air conditioning system equipment, in particular to a fan coil used in an air supply system of an air conditioner. Background technique [0002] The fan coil is one of the terminal devices in the entire air conditioning system. When chilled water or hot water flows through the coil pipe, it exchanges heat with the air outside the pipe, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. Low-noise motor, coil (surface cooler), condensate pan, air filter, air inlet and return, controller, etc. [0003] The working principle of the existing fan coil is as follows: the heat exchange medium is transported into the coil tube and circulates. The air sucked into the room by the fan through the return air inlet traverses the coil, exchanges heat with the cold (hot) medium water in the coil, and then cools and dehumidifies, and then is sent into the room through the air outlet. This repeated cycl...

Problems solved by technology

[0004] However, when the existing fan coil units are used, there are the following problems. Since the inner fan coils (surface coolers) are arranged in a staggered manner relative to the air intake airflow, when the fan is running at a high speed and the gas flow rate is relatively high, it will act on each staggered The degree of turbulence between the airflow behind the coil is relatively large. When the coil produces resistance to the high-speed airflow, the degree of flow velocity loss of the high-speed airflow increases, thereby reducing the efficiency and quality of the air supply. Moreover, the fan coil The inside of the pipe is a rectangular space, and the space is large, and the size of the gas output pipe is smaller than the internal rectangular space of the fan coil unit, which makes it easy to form local turbulence inside the fan coil unit, resulting in increased wind resistance and affecting the air supply efficiency
