Pressure delivery outlet mounting height pressure delivery outlet mounting height, according to the specification, you must set the fire lifts, fire lift should have the front room, also known as the elevator hall, if it is combined and stairwell, then called shared room Such front room was evacuated when a fire provides a temporary buffer space partially into the fire evacuation stairs between excessive and, therefore, requires this space there is a certain air of liquidity, so-called positive pressure air supply, it is to use machines to the outside in the fresh air is piped into the ventilation requirements of this site, this is called positive pressure air supply. pressure delivery outlet from the decorative surface of the aluminum vent damper combination a widely used exit of fire safety requirements of ventilation and air conditioning return air duct or the suction port, usually installed in the duct or duct end and side walls, the usual style for oral use, adjustable air flow direction. Causes pressure delivery outlet dew point temperature to produce a 1: design load air volume or flow rate is too small or too small, causing the upper space temperature is high, the room temperature is high positive pressure blower is installed, so the outlet temperature is low and the formation of large temperature near the outlet , resulting in the formation of the dew point temperature. 2: The new design of the wind is too large, and there is a separate new outlet, especially without fresh air cooling process, thus forming a new air temperature leads to the top of the space temperature, causing condensation. 3: Seal is not good or poor maintenance of the structure leads to an external hot air into the room cause condensation. Such as windows and doors are not closed or opened frequently. There are many reasons, the above analysis of the roof of my friends have positive pressure blower, find the reasons for the problem can be found after treatment for a solution. Measures one: to increase the return air area, appropriate damage return air box, which is to find ways to improve the air temperature positive pressure blower prices, undermine the dew point temperature on it. Option two: to find ways to raise the temperature of the heat exchanger, the water system can be adjusted out of the valve, improving the host water temperature. A refrigerant machine a little difficult, but it can also be appropriate to put fluorine, extend the length of the connecting pipe and other measures to make the evaporation point fluorine advance or delay. Option three: to ensure the sealing of the room. Reduced fresh air. Four ways: many technical approaches, there is no way, only to insulate the positive pressure air blower _ _ positive pressure blower pressure delivery outlet provided by the Texas Huaxin air-conditioning plant. Texas Watson conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) strong, credible, Shandong Texas heat, refrigeration and air conditioning equipment industry has accumulated a large number of loyal customers.
