Design method of integrated box-type self-contained machine room

Abstract

The present invention discloses a design method of an integrated box-type self-contained machine room. The design method comprises the following steps: firstly, selecting equipment parts in line with needs according to requirements of a design drawing for an HVAC system; secondly, optimizing, assembling and connecting the equipment parts, except a host air conditioner, a boiler and a cooling tower; thirdly, integrating the optimized, assembled and connected equipment parts into a protective housing; and finally, integrally testing a water pressure of the protective housing, the equipment parts and joints after washing the protective housing, the equipment parts and the joints, and transporting the same to an installation site of the HVAC system after the water pressure test passes the inspection. The method provided by the invention can improve the installation efficiency of an HVAC machine room and shorten the installation period of the HVAC machine room.

We claim: 
     
         1 . A design method of the integrated box-type self-contained machine room, characterized by comprising the following steps:
 (1) determining a design drawing for an HVAC system; and then selecting equipment parts in line with needs according to requirements of the design drawing for the HVAC system;   (2) optimizing, assembling and connecting the equipment parts, except a host air conditioner, a boiler and a cooling tower, according to the requirements of the design drawing for the HVAC system; and placing the equipment parts on one or more interconnected transportable bases;   (3) integrating the optimized, assembled and connected equipment parts into a protective housing, while reserving a machine port in the protective housing; and assembling and connecting the integrated equipment parts, requiring connecting with the host air conditioner, the boiler and the cooling tower, with the machine port in the protective housing in advance; and   (4) Testing water pressure after integrating and assembling the integrated equipment parts in the protective housing; systematically washing the integrated equipment parts and cleaning up the protective housing after passing the acceptance; packaging and protecting a finished product of the integrated box-type self-contained machine room after inspection, and then transporting the same to the installation site of the HVAC system; and connecting the host air conditioner, the boiler and the cooling tower with an integrated box-type self-contained machine room port through the machine room on the installation site of the HVAC system.   
     
     
         2 . The design method of the integrated box-type self-contained machine room according to  claim 1 , characterized in that the equipment parts comprise piping system parts, electrical system parts and mechanical structural parts of the HVAC system, wherein
 the piping system parts include, but are not limited to a chilled water pump, a cooling water pump, a hot water pump, a filter, a water treatment device, a constant-pressure water supply device, a deoxygenation device, a valve accessory, a flexible connector, a pressure gauge and a thermometer;   the electrical system parts include, but are not limited to a control cabinet; and   the mechanical structural parts include, but are not limited to a pipe rack and a connecting member.   
     
     
         3 . The design method of the integrated box-type self-contained machine room according to  claim 1 , characterized in that the equipment parts can be increased or reduced according to post-installation requirements of the HVAC system. 
     
     
         4 . The design method of the integrated box-type self-contained machine room according to  claim 1 , characterized in that the optimization in step (2) means that a principle for assembling and connecting the equipment parts is to reduce an occupied area, a resistance to working medium in a piping system, and a hoisting height.
