Benefits of technology

The patent proposes a new chiller heater system that addresses issues in previous systems. The new system is designed to be flexible and energy efficient. Its technical effects include improved energy efficiency and flexibility, which address the drawbacks of previous systems.

Problems solved by technology

This system provided many advantages but meanwhile suffered from certain drawbacks, one of which was that by virtue of the reversible nature of the individual modular units, significant design compromises were inherent which led to a reduced energy efficiency compared to non-reversing units.

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to an apparatus and method for converting a modular reversing chiller / heater system to a modular non-reversing chiller heater system.[0003]2. Description of the Related Art[0004]In the past, various systems have been proposed for providing an energy efficient system for building air space conditioning, where a building may require variously simultaneous heating and cooling. Such systems are set out, for example, in U.S. utility patent application Ser. No. 12 / 562,931 and U.S. provisional patent application number 61 / 447,247.[0005]The first such system in the world to utilize a plurality of modular reversible heat pump chiller heater units utilizing a system of virtual moveable endcaps is described in U.S. Utility patent application Ser. No. 12 / 562,931. This application disclosed for the first time an arrangement of interconnected reversible heat pump chiller heaters having on one side of each modula...
