Zero pressure drop water heating system

Abstract

A zero pressure drop water heating system comprising a cold side conductor having a receiving end and a closed end; a hot side conductor having an exit end and a closed end; a pump; a bypass conductorhaving a first end, a second end and a bypass valve, wherein the first end is adapted to the receiving end and the second end is adapted to the exit end; at least one heat exchanger having a flow valve; a heat exchanger inlet temperature sensor disposed on the inlet of one of the at least one heat exchanger; an outlet temperature sensor disposed at an outlet of the at least one heat exchanger closest to the exit end; a system outlet temperature sensor disposed on the exit end and a system inlet temperature sensor disposed on the receiving end.

Description

[0001] Priority and related application [0002] This application claims the benefit of priority of non-provisional application U.S.S.N. 15 / 161,216, filed May 21, 2016, which in turn claims the benefit of priority of provisional application U.S.S.N. 62 / 164,668, filed May 21, 2015. The entire content of said application is hereby incorporated by reference. technical field [0003] The present invention generally relates to a tankless water heating system that can be widely used in applications including high rise buildings or any application where pressure drop is a critical issue. More specifically, the present invention relates to a water heating system configured to overcome not only the pressure drop, but also the pressure rise associated with tankless water heating systems. Background technique [0004] Due to the pressure required to transport water to great heights, high rise buildings have traditionally been serviced using tank water heating systems or boiler and tan...

AI Technical Summary

Problems solved by technology

Introducing a water heater with a large pressure drop results in a greater than desired pressure differential between the hot and cold sides and can cause the building's water distribution system to not function properly

However, previous attempts have not succeeded in maintaining a low pressure drop while avoiding negative pressure effects and simultaneously heating the water on demand

Further, previous attempts have not been successful in producing zero pressure drop conditions under which users of tankless water heating systems would not experience unintentional pressure drop conditions and / or boost condition
