A heat pump generally has a max temperature change of 20 degrees F. If air entering the return duct is 90, it will not be cooler than 70 on the discharge side, Below 60, it is working against the insulation and air infiltration into the house. It is an air conditioner, not a deep freeze. Remember that a heat pump either dumps heat outside to cool a house, or picks up heat from outside to heat the house. If it is 100 degrees outside, it is hard to dump heat. Below 35, it is hard to pick up heat. At an outside temp of 59 degrees, it should work for either- but nobody needs cooling when it is 59 degrees outside. Open a window, already!.

What would happen to liquid with a freezing point of 32 degrees if its temperature dropped below 30 degrees?
It wouldn't t be able to cool down below 32 degrees without freezing first. As heat is take away from the substance, it would first cool down to 32 degrees (assuming it was hotter than that in the first place), then, as more heat is taken away, it would solidify, and only after getting solid will it continue getting colder.

Does heat travel from warm to cool or cool to warm?
Heat travels from warm to cool.
Why won't heat pump cool?
i set my thermostat to cool, my heat pump start it go to heat but not cool, i think the thermostat. can u help.
Why do you say heat up and cool down instead of heat down and cool up?
To heat something means to bring the temperature up and to cool something means to bring temperature down. Hence the terms "Heat Up" and "Cool down". We actually do not need to add the up or down, as heat in itself means to rise, and cool means to lower. So instead of saying "I need to heat my food up", one could just say, " I need to heat my food".

How do you change Mercury powder into liquid Mercury?
You will need to cool it below -39 degrees Celsius (-38.83, plus remove the heat of fusion).

What heat are pumps?
A better way to heat and cool your home - but it may be expensive in the git go. Heat pumps have a problem heating with temperatures below 35 degrees. They can't provide heat if it is below 35 degrees outside. Pipes are laid under ground to use the 55 degree amibent heat there and the heater with 55 degree coolant, the heat is extacted by the heatpump to warm your house. They can also work in the reverse to cool homes. Acting similar to a refrigerator, heat pumps can draw heat from the home and transfer it into the ground and tamp into the cooler ground temperature.

How do you get water to the temperature of 27 degrees?
You can allow hot water to cool or you can heat cold water.
How you can get the metal lid in the jar should you heat it or cool it?
cool it. When molecules are cooled they compress.
