May 13, 2009

Appl. No.:

12/465105

Inventors:

Mark Platt - Sparta WI, US

International Classification:

F25D 19/00

US Classification:

62298, 622591

Abstract:

The invention discloses a modular air conditioning, heating, and heat recovery system. Particularly, the invention discloses a modular system having the condenser and/or evaporator heat exchangers mounted outboard of the modules and being easily removable and separatable by virtue of their positioning and valving.

Appl. No.:

12/270668

Inventors:

Mark PLATT - Sparta WI, US
Benny L. Kincaid - Awon IN, US

International Classification:

F25B 1/00

US Classification:

62498

Abstract:

A heating and/or cooling system which incorporates one or more modular dedicated heat recovery refrigeration units each of which includes at least one compressor, an evaporator and a condenser. The system captures and utilizes condenser circuit heat which would otherwise be wasted. A variable speed circulating water pump circulates water through each evaporator/condenser, which are connected in parallel across the respective supply line and return line. A master controller activates and deactivates individual compressors in accordance with load demand. Shut-off valves close off the water flow through the respective evaporator and/or condenser of any units deactivated and the resulting changes in the pressure differential in the supply and return lines is sensed by sensor which sends a signal to the pump motor speed controller which changes the output of the pump to restore a predetermined pressure differential.

Assignee:

MULTISTACK LLC - Sparta WI

International Classification:

F25B 49/02
F25B 39/02

US Classification:

62527, 62515, 62528

Abstract:

The present invention discloses a heat exchanging apparatus including a plate type heat exchanger auxiliary vessel arrangement whereby the auxiliary vessel contains fluid in more than one phase to enable the corresponding plate type heat exchanger to be flooded with heat exchanger fluid in order to fully employ its heat exchange surfaces in the task of exchanging heat.

Appl. No.:

12/511325

Inventors:

Mark PLATT - Sparta WI, US

Assignee:

MULTISTACK LLC - Sparta WI

International Classification:

F28D 7/00

US Classification:

165164

Abstract:

The present invention is a plate heat exchanger that allows refrigerant to enter the heat exchanger simultaneously from two sides. Allowing the refrigerant or other fluid to enter from two sides splits the flow and improves fluid velocities by presenting an optimized area to the fluid flow. This effect may be realized for both gases and liquids, and for example with respect to a liquid refrigerant, where it enters the heat exchanger simultaneously by splitting. According to the present invention the split liquid flow from the condenser feeds dual electronically controlled expansion valves before entering the heat exchanger. Fully evaporated gas leaves the heat exchanger through a single outlet, or through a dual outlet.

Appl. No.:

Inventors:

Mark Platt - Sparta WI, US
Daniel D. Schmitz - Madison WI, US

Assignee:

MULTISTACK LLC - Sparta WI

International Classification:

F25B 27/00
F25B 1/00

US Classification:

622387, 62498

Abstract:

The invention is a 4 pipe geothermal heatpump heater/chiller device. It includes modular elements each having controllers on every module. A master controller may determine how many modules need to be in heating or cooling mode. The controlling of the modules and the switched four pipe arrangement would allow for any number of the modules to be running alternately in either heating or cooling mode at the same time. In between each module would be a spacer having isolation valves on the input and output side of the load side of each module. The valves would open and close depending on however many modules were desired to be in heating and or cooling mode, respectively. It may be also that a module is redundant, which can then be switched back and forth from either heating and or cooling mode, while the other modules themselves are left in their respective modes.

Inventors:

Mark PLATT - Sparta WI, US

Assignee:

MULTISTACK LLC - Sparta WI

International Classification:

F25B 29/00

US Classification:

62 79, 622381

Abstract:

A chiller heater building air space conditioning system is set out including a plurality of interconnected modular chiller/heater units which can be operated variously in a chilling mode, a heating mode, or an off mode. An arrangement for converting a system comprising reversible modular heat pump chiller heater elements into a system comprising non-reversible modular chiller heater elements is set out.

Assignee:

MULTISTACK LLC - Sparta WI

International Classification:

F25B 29/00

US Classification:

622381

Abstract:

The invention sets out a system of interconnected non-reversing heater-chiller modules having a virtual moveable endcap separating select units. The system facilitates the variable operation of heater/chiller modules in a combination of heating/chilling/simultaneous operation modes, or rest modes, in order to adjust to variable building load, mechanical, and environmental conditions.
