Title: Using the percentage of design flow method, a system that leaks 100 CFM in a system with a design ... Post by: beefybabies on Feb 23, 2018 Using the percentage of design flow method, a system that leaks 100 CFM in a system with a design flow of 1,200 CFM has a leakage rate of:
A) 1,200 CFM - 100 CFM = 11 leakage rate. B) 100 CFM/1,200 CFM = 8 leakage rate. C) 100 CFM/(1,200 CFM - 100 CFM) = 9 leakage rate. D) 1,200 CFM/100 CFM = 12 leakage rate. [Ques. 2] The purpose of TAB is to document that: A) Initial startup adjustments are made. B) The duct system does not leak. C) Each area has the minimum required ventilation. D) The system is performing as designed. [Ques. 3] If the compressor oil on a hermetic compressor is acidic, the next step is to change the: A) Compressor oil once. B) Compressor oil repeatedly. C) System filter driers repeatedly. D) System filter driers once. [Ques. 4] You will never see a pump with a profile of: A) High pressure and high flow. B) High pressure and low flow. C) Low pressure and low flow. D) Low pressure and high flow. [Ques. 5] What type of heat pumps are commonly installed above the drop ceiling in each zone in a commercial building? A) Vertical water source heat pumps B) Air-source packaged heat pumps C) Horizontal water source heat pumps D) Air-source wall mount heat pumps Title: Using the percentage of design flow method, a system that leaks 100 CFM in a system with a design ...
