Abstract
An air handling system is disclosed that includes an integral chilled water refrigeration system. The air handling system additionally includes a first coil section that provides cooling and a second coil section that provides heating. The second coil section and associated terminal units are in fluid communication with the first refrigeration system.
Claims20
An air handling system comprising:
- a. an enclosure defining a first airflow path extending between a first air inlet and a first air outlet;
- b. a first fan located between the first air inlet and outlet;
- c. a first coil section located between the first air inlet and outlet, the first coil section being configured to provide cooling to air flowing through the first coil section;
- d. a second coil section located between the first cooling coil section and the first outlet, the second coil section being configured to provide cooling to air flowing through the second coil section;
- e. a first refrigeration system that provides cooling to the first coiling coil;
- f. a second refrigeration system configured to provide cooling to terminal units associated with the air handling system and heating to the second coil section.

An air conditioning system comprising:
- a. an air handling unit providing a supply airflow, the air handling unit including:
- i. a first heat exchanger for cooling the supply airflow;
- ii. a second heat exchanger for reheating the supply airflow cooled by the first heat exchanger;
- iii. a first refrigeration system providing cooling to the first heat exchanger;
- and
- iv. a second refrigeration system providing cooling to the second heat exchanger;
- b. a plurality of terminal units in fluid communication with the supply airflow generated by the air handling unit;
- c. a plurality of radiant panels or chilled beams in fluid communication with the second refrigeration system;
- and
- d. a pump circulating a working fluid from the second refrigeration system, to the radiant cooling panels or chilled beams, to the air handling unit second heat exchanger, and back to the second refrigeration system.
