As the target temperature of the refrigerator approaches ambient temperature, without exceeding it, the refrigeration capacity increases thus increasing the refrigerator's COP. The SI unit is watt (W). Another unit common in non-metric regions or sectors is the ton of refrigeration, which describes the amount of water at freezing temperature ...
The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the energy consumed in watt-hours.
Increasing the input temperature (e.g. by using an oversized ground source or by access to a solar-assisted thermal bank [10]). Accurately determining thermal conductivity will allow for much more precise ground loop [ 11 ] or borehole sizing, [ 12 ] resulting in higher return temperatures and a more efficient system.
For refrigerating appliances, such as refrigerators, freezers, wine-storage appliances, and combined appliances, the labelling is specified in terms of an energy efficiency index EEI, which is an indication of the annual power consumption relative to a reference consumption that is based on the storage volume and the type of appliance (refrigerator or freezer).
At room temperature it is supplied as gas at 1 bar, so that the system is in the steady state. The Joule-Thomson (JT) cooler was invented by Carl von Linde and William Hampson so it is also called the Linde-Hampson cooler. It is a simple type of cooler which is widely applied as cryocooler or as the (final stage) of coolants.
There isn't a perfect temperature; there's a range. On the cool side, the ideal room temperature is between about 71 and 73 degrees, according to the LG company.

Even Florida has seen a subzero temperature with Tallahassee dropping to minus 2 degrees during the most brutal U.S. cold outbreak on record in Feb. 1899. Montana is the coldest in continental U.S ...
