BOMA-HVAC Verified Answers A metering device ️A component in an AC system That drastically decreases the temperature and pressure of the refrigerant moving from the condenser before it enters the evaporator. It is engineered to govern (regulate) the flow of refrigerant to help regulate pressure. Ammonia, gas, and helium ️Require one BTU to raise the temperature of 1 lb of water by 1°F. Calculation for volume of air ️Change inches to feet and multiply, then multiply by the airflo...
