US Patent:

62933353, Sep 25, 2001
Filed:

Jun 24, 1999
Appl. No.:

9/344210
Inventors:

Jeffrey Tawney - St Petersburg FL
Davod Denorcy - Bradenton FL
Dave Smith - St. Pete FL
Michael Patrick - Clearwater FL
Assignee:

AquaCal, Inc. - St. Petersburg FL
International Classification:

F28D 712
F28D 900
F28F 312
F28F 114
US Classification:

165156
Abstract:

A tube and shell heat exchanger having a transversely oriented inlet port and a spirally coiled heat transfer tube contained within an arcuate chamber created by an internal baffle in which the water to be conditioned travels along a helical pathway in which the flow has minimized water depth and high turbulence. The tube and shell heat exchanger maximizes heat transfer capability in a relatively easy to assemble design to make feasible the use of a higher cost material for the tubing such as titanium in a wide range of applications.

Appl. No.:

17/512324
Inventors:

- St Petersburg FL, US
Jeffrey Tawney - St. Petersburg FL, US
Stanford P. Hudson - St. Petersburg FL, US
Michael Krasowski - St. Petersburg FL, US
Assignee:

AquaCal AutoPilot, Inc. - St. Petersburg FL
International Classification:

G05D 7/06
E04H 4/12
G05D 23/19
Abstract:

A flow rate component, such as a bypass valve with a motorized actuator, a variable speed circulation pump, or both, is controlled in realtime by an automatic controlled to regulate water flow rate through a swimming pool heater, such as a heat pump, to optimize heat transfer, minimize energy consumption, and improve life spans of components of the swimming pool circulation, filtering and heating system.
