What will be the approximate gauge pressure on the low side of a newer model heat pump if the unit is properly charged on a 95 degree day?

The correct answer to this question is D, 70-75. A heat pump is a device which has the ability to transfer heat energy to a heat sink. The pump does this by moving heat from absorbing heat from a cold space and sending the heat to a warmer space.

Heat pumps are used in a lot of our everyday devices such as freezers, refridgerators, space heaters, and air conditioners. The first heat pump was developed between the years of 1855 and 1857 by Peter von Rittinger. Compression and absorption are the main types of heat pumps. Compression heat pumps run on mechanical energy and absorption heat pumps run on an energy source, such as natural gas.
