Improved heat pump

摘要

A heat pump system comprising a water reservoir tank 1, positioned proximate to a building 2 having a remote heat source 3 associated therewith and ducting 5 for drawing said heat source to said tank wherein the tank has an evaporator 4 and fan 6 positioned to draw from the heat source and transfer said heat to the evaporator and a compressor 7 for transferring said heat to said tank. The invention makes use of a Smart Controller designed to optimise the efficiency of heat pump water heaters. The controller uses various inputs including ambient conditions and water consumption data to make an intelligent decision on when to run the system, based on a set of user preferences.
