Energy efficient heat pump systems for water heating and air conditioning
First Claim
1. A heat pump system for water heating and air conditioning, said system comprising:
- a compressor for circulating a refrigerant fluid through said system;
a water tank for storing water;
a first heat exchanger for heating water in said water tank;
a second heat exchanger for rejecting or extracting heat to or from an outdoor environment;
a third heat exchanger and associated fan for conditioning and supplying air to an indoor space, wherein said system is adapted so that;
when heating water stored in the water tank requires heating, the refrigerant fluid exhausted from the compressor passes through the first heat transfer heat to the water in the water tank and then passes trough the second heat exchanger; and
after the water in the water tank is heated to a predetermined temperature, the refrigerant fluid exhausted from the compressor bypasses the first heat exchanger and is directly passed to the second heat exchanger to exhaust heat to the outdoor environment.

Abstract
A heat pump system for providing water heating and air conditioning, comprising one or more compressors for circulating a refrigerant in the system, a hot water tank having a heat exchanger for heating and storing the hot water, an outdoor heat exchanger and a fan for rejecting or extracting heat to or from the outdoor environment in air cooling, or water heating and/or air heating modes of operation respectively, an indoor heat exchanger with a fan for conditioning and supplying air to an indoor space. The system is particularly suitable in applications which require water heating and house cooling all year round. The system may also be adapted to other situations such as year-round water heating with seasonal air cooling, or year-round water heating with seasonal air cooling and heating, etc., and used for different applications, e.g., space heating and cooling simultaneously.
