Answer to Question 1

De-brazing creates a flame hazard from the oil spray being ignited by the torch and poisonous gasses are created when halogenated refrigerants pass through a flame.

Answer to Question 2

Dry bulb temperature the normal air temperature in degrees Fahrenheit Wet bulb temperature the temperature of a thermometer with a wet bulb in degrees Fahrenheit. The wet bulb temperature reading takes the moisture in the air into account.
Enthalpy Measures the total heat content of the air in BTUs per pound of air. Dew point temperature - Measures the temperature where water will start to condense out of the air.
Specific Humidity Measures the weight of water vapor in the air in grains Relative humidity Expresses the percentage of water vapor in the air compared to the amount of water vapor the air can hold.

Specific volume Measures the space in cubic feet occupied by each pound of air.
