The formula for finding the microfarad value of a capacitor is (Amperage X 2650 divided by the applied voltage). Using this formula with amperage measured at 1.5 amps and applied voltage at 115 volts. The microfarad value of the capacitor would be approximately: a. 35 mfd b. 20 mfd c. 12.5 mfd d. 3.5 mfd - a. 35 mfd A closed loop, water sourced heat pump system drawn: a. water from a pond, runs it through a heat exchanger and returns the water back to the pond b. a fluid through sealed tubing loops placed in a pond to a heat exchanger and returns it to the loops c. a fluid through a heat exchanger and rejects the fluid to a storm sewer d. domestic water, runs it through a heat exchanger and returns heated water back to the domestic plumbing - b. a fluid through sealed tubing loops placed in a pond to a heat exchanger and returns it to the loops A common problem with restaurant units is their location near kitchen exhaust. This could cause high discharge pressure in the cooling mode because: a. Return air filter becomes plugged. b. Grease plugs the evaporator. c. Grease plugs the condensate line. d. Grease plugs the condenser coil. - d. Grease plugs the condenser coil
