Answer - recommended air temperatureThe "ideal" rule of thumb most people hear is 20 degrees cooler than the air entering the system. Without having several idicators, including the break down of the particular models ARI ratings, this is hard to determine. What is refered to as the Delta T, or difference in the split, is directly related to the dry bulb temperature but more so the wet bulb temperature. So, the higher the wet bulb which refers to how much moisture is in a cubic foot of air the less the temperature difference is going to be. On a super high efficiency unit, if you say have 80 degrees going into the system with a high relative humidity,(over 71 RH is out of the manufacturers design), then you may only have a 5 degree drop. But if you have 80 degrees entering with a low RH, you may have a 27 degree drop in temperature. This has to do with how much energy it takes to change the state of moisture. It takes 1 BTU to change 1 pound of water 1 degree, but to change the state of moisture , ie 32 degree ice to 32 degrees water (no temperature change!) takes 323 BTU's for that same pound of water. Moisture levels in your home are what rob your system of capacity.

What is cooling rate and how is it measured?

Cooling rate refers to the speed at which a material loses heat during the cooling process. It can be measured by monitoring the temperature of the material over time using a thermometer or sensors. The cooling rate is influenced by factors such as the material's thermal conductivity, its surface area exposed to the surrounding environment, and the temperature difference between the material and its surroundings.


Where is wet bulb temperature measured in the heating mode?

Wet bulb temperature is measured as part of the air temperature when a heater is running. It is measured at the return air grille (near the return air duct) or at the supply air grille (near the supply air duct). It is important to measure wet bulb temperature in the heating mode because it indicates the amount of moisture in the air and helps to determine the amount of cooling or heating that is needed. Wet bulb temperature is measured at the return air grille.Wet bulb temperature is measured at the supply air grille.Measuring wet bulb temperature in the heating mode helps to determine the amount of cooling or heating needed.


What is the recommended temperature for cooling food before refrigeration?

The recommended temperature for cooling food before refrigeration is to bring it down to 70°F (21°C) within two hours and then to 41°F (5°C) or lower within an additional four hours. This process helps prevent the growth of harmful bacteria. It's important to use shallow containers and avoid placing hot food directly in the refrigerator to ensure even cooling.


What is cooling approach temperature?

Cooling approach temperature refers to the difference between the temperature of the cooling medium (such as water or air) and the temperature of the fluid being cooled. It is a critical parameter in heat exchangers and cooling systems, indicating the effectiveness of the cooling process. A smaller approach temperature signifies better heat transfer efficiency, while a larger approach temperature may indicate reduced performance or the need for system optimization.


What is the difference between cooling and chilling?

Chilling is the reduction in temperature of the required solvent below than its wet bulb temperature while the rest is considered as cooling i.e. if we are only reducing the temperature of solvent to an extent such that the final temperature is above its wet bulb temperature than it will be considered as COOLING.


What is process cooling?

What is Thompson experiment?

It is an experiment in which the Joule-Thomson coefficient is measured. Basically, you are expanding a gas under adiabatic conditions to ensure constant enthalpy and you will notice that there will be a temperature change (most likely cooling).


Why is my AC not cooling to the set temperature?

There are several possible reasons why your AC may not be cooling to the set temperature. It could be due to a dirty air filter, low refrigerant levels, a malfunctioning thermostat, or issues with the compressor. It is recommended to have a professional HVAC technician inspect and diagnose the problem to determine the exact cause and provide the necessary repairs.


Why is my air conditioner not cooling to the set temperature?

There are several reasons why your air conditioner may not be cooling to the set temperature. Some common reasons include a dirty air filter, low refrigerant levels, a malfunctioning thermostat, or blocked airflow. It is recommended to check these potential issues and contact a professional if needed for further diagnosis and repair.
