The session deals with design and testing of energy efficient heat pump design. Three different research facets of heat pumps are evaluated here. The first deals with improving efficiency through control system optimization using MATLAB. The second looks at improving the efficiencies of two key heat pumps applications – one being ground source heat pumps and the other being heat pumps for cold climates. Heat pumps suffer from much reduced efficiencies in cold climates, and this paper discusses how to optimize the design to improve capacity and efficiency in these cold climates. The simulations are then compiled into a pareto of options to improve system efficiencies. The third paper discusses long term monitoring of a combination of ground source heat pumps with water heating. The paper looks at the comparison to manufacturer listed COPs and the actual as-observed performance. The water heating efficiency is improved through a desuperheater operated with the ground source heat pump.
