Heat transfer system and environmental control system with heat transfer system

An environmental control system for a structure, the environmental control system comprising:

• (a) a primary distribution system comprising a primary thermal transfer conduit system, the primary thermal transfer conduit system comprises a supply end in thermal communication with a source of at least one of heating or cooling and a first primary distribution end in a first room in the structure wherein, in operation, the primary distribution system provides the heating or cooling to the first room;
• (b) an ambient energy distribution system extending between the first room and a second location in the structure and comprising an ambient energy distribution conduit system, the ambient energy distribution conduit system extends between a first end in thermal communication with a first location in the first room and a second end in thermal communication with the second location in the structure, wherein, in operation, the ambient energy distribution conduit system transfers heat between the first and second locations whereby, in operation, the heat provided to the first room by the primary distribution system is transferred to the second location by the ambient energy distribution system, wherein the ambient energy distribution system is fluidically separate from the primary distribution system, wherein the ambient energy distribution system comprises a fluid flow path which circulates a fluid for the heating or cooling, a first heat exchanger positioned in the first location and a second heat exchanger positioned in the second location, and wherein the fluid in the fluid flow path is circulated between the first heat exchanger positioned in the first room and the second heat exchanger in the second location whereby the heat is transferred between the first room and the second location.
