A water source heat pump is defined as a device that utilizes the energy in a body of water to provide heating and cooling for a building or structure. It works by transferring heat energy from the water to the space or vice versa. The water source heat pump is an energy efficient and cost effective way to heat and cool a space as it takes advantage of the natural heat in the water and does not require the use of external energy sources. The most common type of heat pump uses a closed loop of pipes, which are placed in a body of water. The heat pump circulates the water through the loop, collecting and transferring the heat energy to the space or vice versa. The system also utilizes a compressor, which helps to regulate the temperature of the water. In addition, a fan is used to move the heated or cooled air throughout the building or structure. The water source heat pump is an excellent alternative for heating and cooling large spaces as it can provide a much more efficient and cost effective system
