Abstract

The invention discloses a ceiling fresh air handling unit system resisting freezing in winter, which comprises a fresh air unit, an electric airtight valve, a manual airtight valve, a single-layer louver, an iron sheet short tube, a fireproof valve, an air duct of a fresh air unit system, a system supporting and hanging frame and a fresh air unit supporting and hanging frame. When the outdoor and indoor temperature difference is large, the electric airtight valve is directly closed, and the manual airtight valve is opened to ensure that indoor air flows to the fresh air unit system through the manual airtight valve under the action of indoor heat pressure, outdoor heat pressure and wind pressure so as to effectively prevent the temperature of water in a copper tube of the fresh air unit system from excessively reducing to achieve the purpose of resisting the freezing. Indoor heat is fully utilized, and a large quantity of energy sources can be saved under the condition of meeting the operating requirement.

Description

technical field [0001] The invention relates to a suspended ceiling fresh air unit system, in particular to a suspended ceiling fresh air unit system for anti-freezing in winter. Background technique [0002] In the cold and sandy areas of northern my country, the heating coil of the ceiling fresh air unit is often cracked by freezing. The main reason is that the fluid in the heating coil is affected by the cold wind, and the volume of the fluid in the heating coil expands when it solidifies, which eventually causes the heater coil to swell. This not only affects the normal operation of the fresh air unit, but also increases the maintenance of the equipment and the user's operation and management costs, and also affects the popularization and application of the ceiling fresh air system in cold regions of our country to a certain extent. [0003] In the past, the operation of the ceiling fresh air unit in winter was that the outdoor fresh air was directly sent into the room th...
