BACKGROUND OF THE PRESENT INVENTIONIn all current HVAC systems, during installation of a main machine room, main materials and auxiliary materials need to be transported to the site; and the measurement and setting-out, pipe cutting and welding installation need to be carried out manually on site. Concrete equipment bases need to be prefabricated for a main engine, a boiler, a cooling tower, a water pump, a water treatment device, a constant-pressure water supply device and other equipment parts. The pipe blanking and welding installation is carried out on site after specific locations are determined and the equipment is put in place. Valve members for pipes include traditional Y-type filters, buffer check valves, butterfly valves, gate valves, flexible rubber joints and the like. Steel pipes are mounted in a galvanized steel pipe threaded connection, spiral welded pipe welding or seamless steel pipe welding manner; the measurement, positioning, blanking, cutting, installation threading or welding are carried out on installation site; and all work is completed on construction site.
