The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

Thermal Moisture Enhanced Gradient Strata (TMEGS) for Heat Exchangers optimizes the performance of energy flows for building heating, cooling, hot water, and industrial processes. TMEGS are temperature and moisture control layers which reduce the cost of closed loop ground heat exchangers and increase heat exchanger performance by improving energy transfer between solar, geothermal, process heat and renewable energy exchangers. Circuit optimized thermally active building structures (COTABS) configure heat exchangers and thermal energy strata for application specific requirements. TMEGS integrated with COTABS is a scalable and interoperable carbon-free, planet friendly architecture for net zero energy buildings. Embodiments include the use of recycled materials, waste tire derived aggregate, nanofluids, phase change materials, cathodic protection, and integrated microprocessor and client-server controls.

Pre-mix fuel fired appliances having improved heat exchange interfaces are disclosed. Embodiments may include a fuel-fired heating appliance having a burner, a first housing comprising an outlet, the first housing disposed adjacent the burner and configured to receive combustion gas from combustion at the burner, and a heat exchanger having a heat exchanger tube with a first bend and a second bend, and an inlet disposed adjacent the outlet of the first housing. The heat exchanger may be configured to receive combustion gas from the first housing. The appliance may include a blower configured to direct air toward the first bend of the heat exchanger tube, and a heat transfer insert disposed at least partially in the heat exchanger tube, the heat transfer insert having a first end disposed in the first housing, and a second end disposed adjacent to the first bend of the heat exchanger tube.
