2. WO/2015/030597 MULTI FUNCTION HEAT PUMPWO05.03.2015
F25B 13/00
PCT/NO2014/000039LANGÅKER, John MagneLANGÅKER, John Magne
This invention is a heat pump based on an existing air-to-air heat pump design with an external component consisting of a refrigerant circuit with a compressor and an evaporator/condenser, and an internal component (room unit) with a con¬ denser/evaporator. Less energy is required to heat modern homes. It is therefore challenging to find good solutions that can maintain sufficient indoor heating and hot water while using renewable energy at a cost low enough to make it economically prudent. New technical requirements also demand that a minimum proportion of energy is provided by renewable energy sources. Traditional air-to-air heat pumps are affordable, reasonably easy to install and are very efficient. However, they can only provide indoor heating. Air-to-water and water-to-water heat pumps can be used to heat both rooms and water, but these solutions are expensive to purchase and install. There are a few ventilation heat pumps with a hot water storage tanks, but these are inefficient and do not provide a sufficiently comfortable environment. It has been discovered that a hot water storage tank can be connected to an air-to- air heat pump, with minor alterations, creating an air-to-water-to-air heat pump. The hot water storage tank must have a specific design, but the solution would be inexpensive to produce, easy to install and very efficient. Thus the demand for both room heating (or cooling), as well as hot water, would be fulfilled.
