Temperature conditioning radiant wall system for buildings

Abstract

A temperature conditioning system for a plurality of suites of a high rise building is provided utilizing at least domestic hot water circulated through tubing fit to a radiant wall in a suite for heating the suite. A hot water heating system in communication with a supply riser and return riser provides hot water at variable pressure to each of the multiple serviced floors. Hot water is cirulated through distribution mains to radiant walls in the suites at full riser pressure, while pressure reducing valves off of the distribution mains lower the hot water pressure to domestic service pressures at plumbing fixtures. Similarly, domestic cold water can be chilled and circulated through the radiant walls for cooling. Three-way valves at the radiant wall can alternately circulate hot water or cold water under thermostatic control.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of co-pending US application 10 / 851,349 entitled “MULTI-STORY WATER DISTRIBUTION SYSTEM” and which was filed May 21, 2004, the entirety of which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to systems for the heating and cooling of buildings, reduction in capital expense, and the distribution of water for minimizing the number of piping risers and avoiding over-pressure supplies through the strategic placement of pressure reducing valves. BACKGROUND OF THE INVENTION [0003] Heating and cooling systems for multi-story buildings typically use specifically supplied and circulated hot and cold water for delivery to heat exchangers. Traditionally, room-by-room heating, and air conditioning systems in large buildings have been, what are known in the art, as four-pipe fan-coil systems; two pipes for chilled water flow, and two pipes for heated water fl...

AI Technical Summary

Benefits of technology

[0008] Applicant has provided a system which significantly reduces the piping needed to supply domestic hot and cold water to one or more units, residences or suites in high rise buildings, solves issues associated with the supply of water at pressures above desired domestic use pressures, and incorporates novel heating concepts for multi-residence buildings. The number of risers throughout can be reduced in number by more than an order of magnitude. Noise issues associated with flow in risers extending through each suite is eliminated.

Problems solved by technology

No longer do domestic water pressure and plumbing fixture requirements limit the use of common risers at full pump pressure at full hydrostatic head.

Further, the system has several solutions for ensuring hot water availability and avoiding stagnation which can occur in some domestic lines, contrary to public safety and contrary to plumbing regulations in some jurisdictions.
