corresponding pipe duct valves.
Cooling load calculations should be based on the parameters in the application of project profiles Hongye software to draw cooling load ; determine the pision of air conditioning systems and system solutions should be determined by the actual advantages and disadvantages of the various parameters of the commercial plaza air conditioning system ; select the cold source , is based on data obtained Hongye software to choose ; design and calculation of wind systems , planning and design of the drawings , and through hydraulic calculations to verify ; indoor air supply and air distribution in the form of selected using air fan coil system , a new way of fan coil air supply with a single set of new air system, separate supply room ; design of water systems , plumbing layout should take into account the layout of each room , and the water system and planning ; duct system insulation and plumbing system design should comply with pipe insulation and corrosion requirements .
Detailed requirements are as follows : load calculation part: Hongye envelope HVAC load calculation software is not included in the new wind load , in order to avoid the calculation results with the actual value of the software to produce errors , and therefore need to be some correction to make office buildings cooling load range falls (80 ~ 120W / m²), winter heat load (40 ~ 100W / m²). New wind load should be calculated separately.
Air system components: the number of square units through each room and 30m ³ / (h • person ) fresh air to determine the fresh air of each room , and through the [ 2 ] determine the segment of new air damper tube size. Determination of the exhaust pipe is also true. Also need to be installed in accordance with the relevant specifications corresponding damper .
Water system components: the translation of each room by cooling water outlet pipe flow , estimate the corresponding pipe diameter, and identify the most unfavorable water cycle refrigeration cycle resistance calculations to determine the pump head .
Partially furnished room : the combination of design experience for a reasonable arrangement , aimed to facilitate daily operations and machine
maintenance.
Insulation , corrosion parts: determined in accordance with design specifications , its role is to avoid unnecessary loss of cold heat.
