Heat pump apparatus and method
First Claim
1. A temperature and humidity control system comprising:
- a heat pump including a compressor, an inside air coil and an outside air coil;
vaporizable refrigerant contained in a closed conduit communicating with said compressor, said inside air coil and said outside air coil;
a regeneratable dessicant material;
valve and conduit means for selectably directing air into and communicating with said inside air coil, said outside air coil and said dessicant material, said valve and conduit means comprising;
first means operable in a cooling/dehumidifying mode for supplying inside air first to said inside air coil and from said inside air coil to said dessicant material, and from said dessicant material to a volume sought to be conditioned;
second means operable in a heating/humidifying mode for supplying air first to said inside air coil and from said inside air coil to said dessicant material for humidifying of said air and thence to a volume sought to be conditioned;
third means operable in said cooling/dehumidifying mode for supplying outside air first to said outside air coil and from said outside air coil to said dessicant material for dehumidifying said dessicant material;
fourth means operable in said heating/humidifying mode for supplying outside air first to said outside air coil and from said outside air coil to said dessicant material for regenerating said dessicant material; and
fifth means operative in a heating/humidifying/frost avoidance mode causing outside air to communicate first with said dessicant material and thence with said outside air coil.

Abstract
A temperature and humidity control system including a heat pump including a compressor, an evaporator and a condenser; vaporizable refrigerant contained in a closed circuit communicating with the compressor, evaporator and condenser, a regeneratable dessicant material, valve and conduit apparatus for selectably directing air into and communicating with the condenser, evaporator and dessicant material and including first apparatus operable in a cooling/dehumidifying mode for supplying air first to the evaporator and from the evaporator to the dessicant material, and from the dessicant material to a volume sought to be conditioned and second apparatus operable in a heating/humidifying mode for supplying air first to the condenser for heating of the air and from the condenser to the dessicant material for humidifying of the air to a volume sought to be conditioned.

6. A method for providing temperature and humidity control to a volume comprising:
-
cooling/dehumidifying mode operation including the steps of feeding warm moist inside air first to an inside air coil of a heating pump, thence to a dessicant material and thence to the volume sought to be conditioned and supplying outside air first to said outside air coil and from said outside air coil to said dessicant material for dehumidifying said dessicant material; heating/humidifying mode operation including the steps of supplying inside air first to said inside air coil for heating of said air, and from said inside air coil to said dessicant material for humidifying of said air and thence to a volume sought to be conditioned and supplying outside air first to said outside air coil and from said outside air coil to said dessicant material for regenerating said dessicant material; and heating/humidifying/frost avoidance operation including the steps of supplying inside air first to said inside air coil for heating of said air, and from said inside air coil to said dessicant material for humidifying of said air and thence to a volume sought to be conditioned and causing outside air to communicate first with said dessicant material and thence with said outside air coil.
