Water to air switching flow heater chiller

A switching flow system comprising:

• a switching flow system housing;
• a heating/cooling coil including a coil inlet and a coil outlet, wherein said heating/cooling coil is positioned within said switching flow system housing;
• a fan positioned within said switching flow system housing, wherein said fan is configured to blow air across said heating/cooling coil;
• a switching flow apparatus positioned within said switching flow system housing, said switching flow apparatus comprising:
• a refrigeration loop, wherein said refrigeration loop includes a compressor, a first heat exchanger, an expansion valve, and a second heat exchanger;
• a source return inlet and a source supply outlet;
• a production return inlet and a production supply outlet;
• one or more valves in fluid communication with one or more of said source return inlet, said source supply outlet, said production return inlet, and said production supply outlet;
• wherein said one or more valves are controllable to direct fluid from said source return inlet to either said first heat exchanger or to said second heat exchanger and direct fluid from said production return inlet to the other of said first heat exchanger and said second heat exchanger;
• a source loop including a source return line in fluid communication with said source return inlet and including a source supply line in fluid communication with said source supply outlet;
• a production loop including a production supply line in fluid communication with said production supply outlet and said coil inlet, and a production return line in fluid communication with said production return inlet and in fluid communication with said coil outlet;
• wherein in a cooling mode, said one or more valves are arranged so that said source loop is in fluid communication with said first heat exchanger and said production loop is in fluid communication with said second heat exchanger;
• and
• wherein in a heating mode, said one or more valves are arranged so that said source loop is in fluid communication with said second heat exchanger and said production loop is in fluid communication with said first heat exchanger.
