Abstract

The present invention is a water source heat pump using various modular components to determine and locate the air flow pattern through and around in multiple patterns as assembled post production in the heat pump system. The current invention uses conventional water source heat pump components, assembled in modules including a refrigerant system using a heat exchange medium existing in both the gaseous and liquid form during operation and includes all other necessary components for control, air movement, and commonly occurring processes as in conventional water source heat pumps. The current invention will use an industry standard geothermal or geoexchange source as with the earth as a heat source for heating and a heat sink for cooling in a commonly referred to as an “open loop” or “closed loop” fashion, or as a water source heat pump utilizing a mechanical means for heating or cooling a source liquid.

FIELD OF THE INVENTION

The present invention relates to a modular water source heat pump that can be assembled to allow for multiple air flow patterns.

BACKGROUND OF THE INVENTION

There are four problems related to water source heat pumps currently manufactured: The first problem facing water source heat pumps is the need for a manufacturer or distributor to carry a wide range of geothermal equipment in many different configurations. Most current manufacturers and distributors must stock a multitude of water source heat pumps in various capacities and at least 5 different airflow configurations consisting of at least a left return top outlet system, a right return top outlet system, a left return bottom outlet system, a right return bottom outlet system, and occasionally a “split” system where the air handling section is separate from the compressor/heat exchanger section. By implementing a modular water source heat pump, the main components—that are interchangeable within a range of capacities—enable a manufacturer or distributor to stock individual modules. This allows a manufacturer or distributor to carry less total inventory and be more suited to meet the varied needs of its customers. In addition, water source heat pump modules can be packaged individually, for easier warehousing and decreased shipping damage.
The second problem is that there are no manufacturers building a “straight through” water source heat pump. Most conventional heating and cooling systems are based on a “straight through” airflow configuration; where return air enters the unit from the top or bottom of the unit, and exits through the opposite end. In other words, intake air will go straight through the system. This modular water source heat pump would require less space, be less expensive, and less difficult to install versus the existing left or right air intake/top or bottom outlet style water source heat pumps available. It is important to note that a very large number of furnaces and air handlers are installed in closets in the interior of a home. With currently manufactured water source heat pumps are installed in a closet, air must enter from the left or right side. In most applications, there is not enough room in the closet to install the system.
The third problem is serviceability. Currently manufactured water source heat pumps are difficult to service due to the amount of components contained within a single enclosure. The added convenience of multiple service access panels and the ability to access components within individual modules improves service access greatly.
The fourth problem is that with currently manufactured water source heat pumps utilizing a single enclosure, if one major component fails, it may necessitate the replacement of the entire water source heat pump. Service life of the individual water source heat pump components can vary. In a modular water source heat pump, if a major component fails, only that module would need to be replaced.

SUMMARY OF THE INVENTION

The present invention is a water source heat pump using modules to accomplish the mechanical refrigeration heat transfer that can be assembled to allow multiple airflow patterns and configurations.
This modular water source heat pump can provides multiple airflow configurations.
These airflow configurations are summarized as follows:

- 1. “Left Return Upflow”
- 2. “Right Return Upflow”
- 3. “Left Return Downflow”
- 4. “Right Return Downflow”
- 5. “Straight-Through Upflow”
- 6. “Straight-Through Downflow”
- 7. “Split-System” with remote air distribution module or other air distribution system

The modules can be assembled as a sub-assembly to allow for a “Split-System” whereas the compressor module may be located separately from the air distribution module. When installed in this configuration, the compressor module may be placed separately from the supplied air distribution module or with another manufacturer's air distribution unit. The compressor module may be connected by means of refrigerant piping to a refrigeration coil on a fossil fuel, electric, or other heating and cooling unit.
