Explosion-proof positive draft air-conditioning unit

Abstract

The invention discloses an anti-explosive positive-pressure ventilation air conditioner unit, which comprises a casing, an anti-explosion heater, an evaporimeter and a condenser that are arranged sequentially at upper, middle and lower part on the same side wall of the casing. The anti-explosion heater, the evaporimeter and the condenser are respectively located in the upper, middle and lower isolating chamber in the casing. In the middle isolating chamber, an anti-explosion blower is provided; in the lower isolating chamber, a compressor is provided. The air-in and air-out port of the anti-explosion blower are respectively connected with the upper and the lower isolating chamber. On the side wall of the casing corresponding to the upper and the lower isolating chamber, a blowing-in port and an air-return port are provided respectively; on a side wall of an analysis room, an air inlet and an air return port are provided respectively; the blowing-in port and the air-return port on the side wall of the casing are respectively communicated with the air inlet and the air return port of the analysis room. On the pipe at the air-return port of the casing, a fresh-air inlet is provided. The invention will not influence the temperature controlling, can meet the requirement for constant temperature when the analysis room needs positive pressure and is exchanging air. The invention is applicable for the controlling of positive pressure, air exchanging and temperature in an analysis room in the petrochemical industry.

Description

technical field [0001] The present invention relates to an air conditioner. Specifically, it is an explosion-proof positive pressure ventilation air-conditioning unit for analysis rooms, which is suitable for positive pressure, ventilation and temperature control in petrochemical analysis rooms. Background technique [0002] At present, in the petrochemical analysis room production industry, in order to meet the positive pressure, ventilation and temperature control requirements in the analysis room, most of them use single or double fans to achieve positive pressure ventilation, and use one or more explosion-proof air conditioners to achieve temperature control. Especially for the dual air-conditioning system, when the design layout is unreasonable, the cold air of the air conditioner will be short-circuited and directly discharged outside, which will seriously affect the temperature control. On the other hand, because the fan system and the air conditioning system cannot...

Problems solved by technology

Especially the dual air-conditioning system, when the design layout is unreasonable, the cold air of the air conditioner will be short-circuited and directly discharged outside, which will seriously affect the temperature control

On the other hand, because the fan system and the air conditioning system cannot be matched consistently, that is, the cooling capacity of the fresh air required to be processed per hour of ventilation is beyond the reach of general explosion-proof air conditioners. Therefore, it cannot meet the positive pressure requirements of the analysis room. and the most basic requirement of constant temperature during ventilation
