Explosion proof type forced draft air conditioning device for driller room

Abstract

The present invention relates to an explosion proof type forced draft air conditioning device for a driller room. The explosion proof type forced draft air conditioning device comprises main engine refrigerating systems, internal circulating air ducts, an exhaust air duct, a positive pressure detection and control system and a control system; the main engine refrigerating systems are double systems, each group of main engine refrigerating system comprising a compressor, an oil separator, a finned condenser, a liquid accumulator, a finned evaporator and a gas-liquid separator which are connected in series in turn; the internal circulating air ducts comprise an air treatment air duct, an air return air duct and an air delivery air duct; the exhaust air duct comprises an exhaust duct, a pressure relief air valve and a switching air valve; the positive pressure detection and control system comprises a differential pressure gauge and a communicating tube; a temperature and humidity sensor is arranged at an air outlet of the air delivery air duct; and the compressor, an axial flow fan, a forced draught blower, the pressure relief air valve, the switching air valve, the differential pressure gauge, the temperature and humidity sensor and power-driven air valves are all connected with the control system. The explosion proof type forced draft air conditioning device is applicable to high-temperature environments, and multiple air ducts are adopted to ensure positive pressure of the room, thereby ensuring comfort and raising adjusting precision.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a positive pressure air supply air conditioning system. Background technique [0002] The driller's control room is the control center of the oil drilling rig, which is greatly affected by temperature and humidity, and is generally located in high-temperature areas in the Middle East. The summer temperature is higher than 55°C, and the requirements for air conditioning are high. At present, superchargers and explosion-proof window machines are generally used in the market, and the comfort control accuracy is poor, which can no longer meet the cooling and positive pressure requirements. Contents of the invention [0003] The purpose of the present invention is to provide a special air-conditioning system that can be used in high-temperature environments and adopts multiple air ducts to ensure room positive pressure, so as to overcome problems such as uneven air supply temperature, h...
