Core TradesCâu 98 / 700
During a split-system AC installation, the refrigerant line set is run with several tight kinks and an excessively long distance beyond the manufacturer's limit. The MOST likely result is:
a.Improved cooling capacity
b.Lower compressor amperage
c.No effect on performance
d.Reduced capacity and possible compressor damage from restricted refrigerant flow and improper oil return
Giải thích
Kinked, over-long refrigerant lines restrict flow, cause pressure drops, and impair oil return to the compressor, reducing capacity and risking compressor failure. It does not improve capacity, lower amperage, or leave performance unaffected.

- A gas furnace is installed in a small, tightly sealed closet with no combustion air openings. The MOST likely dangerous consequence is:
- CALCULATION: A common rule of thumb provides 1 square inch of combustion air opening per 1,000 Btu/h of appliance input when air comes from inside a large space. For a 100,000 Btu/h furnace using two openings (high and low), what free area does EACH opening need under this rule?
- A large commercial kitchen exhaust hood removes a high volume of air. Without makeup air, the space goes into strong negative pressure. The BEST solution is to:
- CALCULATION: A room measures 20 ft by 15 ft with a 10-ft ceiling. A ventilation system supplies 500 cubic feet per minute (CFM). Approximately how many air changes per hour (ACH) does this provide?
- A clothes dryer exhaust duct is run with several sharp bends and a long concealed length, then vented into an attic. Two problems with this install are:
- A high-efficiency (condensing) furnace produces acidic condensate. This condensate must be:
