A temperature is an objective comparative measure of hot or cold. It is measured by a thermometer, which may work through the behavior of a thermometric material, detection of thermal radiation, or particle kinetic energy. Several scales and units exist for measuring temperature, the most common being Celsius (denoted °C; {centigrade}), Fahrenheit (denoted °F), and in science, Kelvin (K). The coldest theoretical temperature is absolute zero, absolute zero is denoted as 0 K on the Kelvin scale, −273.15 °C on the Celsius scale, and −459.67 °F on the Fahrenheit scale. At zero K the thermal motion of atoms and molecules reaches its minimum – classically, this would be a state of motionlessness, but quantum uncertainty dictates that the particles still possess a finite zero-point energy. A real system or object can never be brought to a temperature of absolute zero by thermodynamic means.
The wet-bulb temperature is the temperature a given volume of air would have if it were cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat being supplied by the volume of air.
The dry-bulb temperature (DBT) is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture. DBT is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature.
The thermodynamic wet-bulb temperature is the temperature a volume of air would have if cooled adiabatically to saturation by evaporation of water into it, all latent heat being supplied by the volume of air.
Dew point temperature or dew point is the temperature at which a given concentration of water vapor in air will form dew. More specifically it is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation. A higher dew point indicates more moisture in the air; a dew point greater than 20 °C (68 °F) is considered uncomfortable and greater than 22 °C (72 °F) is considered to be extremely humid. As the temperature falls, the relative humidity rises, reaching 100% at the dew point, at least at ground level. Dew point temperature is never greater than the air temperature, since the relative humidity cannot exceed 100%

1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0°C in 24 hours. Based on the latent heat (also heat of fusion) being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW.
Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process.
The heat (energy) required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature.
Same heat (energy) is release when the process is reversed when we condense a vapor into a liquid or a liquid into a solid, without change of temperature.

Energy is a measure of how much fuel is contained within something, or used by something over a specific period of time.
The BTU is a unit of energy.
The British thermal unit (BTU or Btu) is a traditional unit of work equal to about 1055 joules. It is the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit.
 
1 BTU = 1.05506 KJ = 0.000293072 kWh
The kilowatt hour (symbol kWh, kW h) is a derived unit of energy equal to 3.6 mega joules. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt-hours is the product of the power in kilowatts and the time in hours.
 
1 kWh = 3412.14 BTU = 3600 kJ
The joule (J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred (or work done) to an object when a force of one newton (1 N) acts on that object in the direction of its motion through a distance of one meter (1 Newton meter or Nm). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second.
1 kJ = 1000 J
