Benefits of technology
[0018]Finally, a processed air outlet is disposed within the air output section of the housing between the bypass damper and the post-conditioning chamber and allows processed, or conditioned, air to pass into the room to be heated or cooled.
[0027]The preferred heating and cooling system also includes a first check valve and a second check valve. The first check valve is in communication with a refrigerant line from the compression subsystem and the refrigerant coil of the preconditioning coil chamber and is disposed so as to control a flow of refrigerant to the refrigerant coil of the preconditioning coil chamber. The second check valve is in communication with the refrigerant coil of the preconditioning coil chamber and the refrigerant inlet of the drenched coil of the coil drenching spray system. In such embodiments, the output from the computer program product of the operating system controls a position of the first check valve and the second check valve. During the heating cycle, the check valves direct the refrigerant flow through the refrigerant coil of the preconditioning coil chamber for increased heating efficiency. During the cooling cycle, the check valves direct the flow around the preconditioning coil chamber, providing increased efficiency of the drenched coil.
[0032]It is a further aspect of the invention to provide a system for heating and cooling that automatically controls its operating mode to optimize efficiency and comfort.
[0033]It is a further aspect of the invention to provide a system for heating and cooling that maintains the coil leaving wet bulb temperature, thereby increasing system efficiency and comfort.
Problems solved by technology
However, they suffer limitations due to their use of the outside air as a heat source or sink, as the higher temperature differential during periods of extreme cold or heat leads to a lower efficiency.
As the amount of heat that can be absorbed the air is greatly impacted by its humidity, and as the humidity of air is greatly variable from day to day, the use of the dry bulb temperature for control of conventional systems during the cooling cycle leads to further inefficiency.
When used for cooling, the overall efficiency of conventional heat pumps is also reduced due to their failure to use the waste heat for useful purposes.
Another problem with any air conditioning processes is the need to add sensible heat back into the air after it has been de-humidified.
The reason for this that lower temperature air has higher relative humidity and the failure to add sensible heat can result in excessively high relative humidity levels.
This process is typically performed by an electric heater, or a hot refrigerant, which further reduces the efficiency of the system.
However, as these systems are limited to cooling and operate most efficiently under certain ambient conditions, they have heretofore not been readily adapted for use in applications that require both heating and cooling.
As was the case with the drenched coil systems above, these systems are limited to cooling, operate most efficiently under certain ambient conditions, and have not heretofore been adapted for use in applications that require both heating and cooling.

Embodiment Construction
[0045]Referring first to FIG. 1, the system 50 of the present invention includes five primary sub-systems 100, 200, 300, 400, 500. The first sub-system 100 is referred to as the “air processor”. The air processor 100 conditions air for human comfort and hygiene and moves the conditioned air into the desired space. The second sub-system is the compression sub-system 200. The compression sub-system 200 moves heat in and out of the system 50. The third sub-system 300 is referred to as the “heat box”. The heat box 300 determines whether excess system heat is recovered for reuse or rejected to the atmosphere during the cooling cycle and whether the heat is taken into the system 100 from the atmosphere or from the thermal storage loop during the heating cycle. The fourth sub-system 400 is referred to as the “recuperator”. The recuperator 400 is a heat storage system that allows heat to be stored for use at a later time, both during heating and cooling, and transferred to the air processor...

Description
FIELD OF THE INVENTION[0001]The present invention relates to systems for heating and cooling and, in particular, to air processors and forced air systems for heating and cooling an enclosed space.BACKGROUND OF THE INVENTION[0002]Systems for heating and cooling air in an enclosed spaced, such as a home or office building, have been used for many years. Traditionally, separate systems had been used for heating and for cooling. However, a number of systems have been developed to perform both functions. One such system is a heat pump.[0003]A heat pump is a machine or device that moves heat from one location to another location using work. Many heat pumps move heat from a low temperature heat source to a higher temperature heat sink. One common type of heat pump works by exploiting the physical properties of an evaporating and condensing fluid known as a refrigerant. In heating, ventilation, and cooling (HVAC) applications, a heat pump normally refers to a vapor-compression refrigeration...
