Intelligent heating and cooling for buildings

Henan Runheng Energy Maganement Co., LTD have developed intelligent heating and cooling technology for building by recharging shallow geothermal energy in the same well. The company claims that their technology matches the amount of effluent to backwater and reaches adequate heat exchange between backwater and soil. This greatly improves the efficiency of the heat pump unit. In the full closed cycle, water remains unpolluted. Furthermore, the technology overcomes the defect of water heat pump recharging in multiple wells. It solves the problem of the heat source well blockage and declining water levels.

Bamboo winding pipelines to replace piping

Zhejiang Xinzhou Bamboo-based composites technology co., Ltd have developed a technology for bamboo winding pipelines that uses resin as adhesive instead of harmful chemicals. The company claims that bamboo pipes produced with their technology meets the security evaluation criteria of distribution equipment for drinking water. Thus, the solution has the potential to replace some welded steel pipes, PE pipes, and other traditional pipes in the market. Bamboo wood is a fast-growing source of timber which can be produced sustainably.

Module with heat-superconducting material and PV

Solar hot water and PV power are the two main approaches to utilize solar energy at present. However, the energy conversion efficiency of solar water heater and PV modules still needs to be improved, and the average service life of water heater is only 3-5 years. Ecoway Energy Technology Group developed a micro heat pipe array heat using superconducting materials. Its thermal conductivity is about 5000 times greater than aluminium and with a high efficiency and durability. It avoids the common problems of traditional flat solar collector such as solder joints cracking, high antifreeze cost etc, which prolongs the lifetime.

Speed control technology to capture slip-loss energy

Jiangsu Magnet Valley Technology Co., Ltd. Produces winding permanent magnetic coupling adjustable speed drive in motor system. It is a kind of non-contact permanent magnetic drive technology which consists of permanent magnetic rotor, winding rotor and the control system. When there is speed difference between the p-m rotor and winding internal rotor, induced electromotive force will be generated in the winding. By controlling the induced current, speed control and soft start can be realized. During power transmission, the slip power is converted into electric energy to be fedback and reused, which is efficient and energy saving; completely solving the problem of temperature rise of other variable speed regulating devices.

Cold-rolled ribbed steel bar with high ductility

Anyang Heli Techtronic Metallurgy New Technology Co., Ltd have developed cold-rolled ribbed steel bar with high ductility. It combines several manufacturing techniques to enhance the strength of steel bar, and then improves its ductility with heat treatment process to eliminate residual stress and repair the microstructure defects. The company claims that, compared to traditional hot-rolled technique, their technology saves about 40% of energy, as well as alloy materials, such as vanadium nitrogen, manganese silicon. Furthermore, to produce a ton of steel with their technology could save 130 kwh of power, as well as 9.3 kg standard coal, and cost near zero amount of water.

Food waste management by Black Soldier Fly

Food waste and nutrition recovery innovation through the use of biologically-produced enzymes. The concept is similar to 'farming' using an insect larvae of the black soldier fly. The larvae breaks down waste, creating a usable protein fixed in the insect. The larvae can be processed for a variety of feed uses as a sustainable additive. Instead of farming the solution on a large scale, the company aims to provide the service at the household level.

Smart air dome space for recreation facilities

Traditional recreational facilities are costly to build and to operate. The Air Dome saves on construction time and cost. Due to the airtight feature and high efficiency insulation system, the MetaSpace Air Dome could save 2/3 of the energy cost compared with conventional sports facilities of the same size. MetaSpace Air Dome uses high performance architectural fabric as the dome’s “shell”. This is prefabricated off-site, and then assembled and inflated by an intelligent mechanical unit to form the envelope of the structure. The Air Dome combines advances in aeromechanics, new materials, ergonomics, energy saving and environmental protection to provide space for recreational facilities, logistic and warehousing centers.

Copper restoration system

The technology uses copper-based and nickel-based nanocomposites to remanufacture copper base material. The target of the technology is primarily for continuous casting mouldings. Wear layers in the mould are resistant, but eventually become obsolete after repeated use. The wear layers of the moulds can be improved by the applications of the nanocomposites, reducing the amount of wear and thus, the waste from the casting process.

Switching mode power supply (SMPS) Programme

The innovation utilizes high efficiency switching power in electricity meters. The market is aimed at replacing those that use inefficient linear power technology. The energy consumption of electricity meters decrease from 1.5W to 0.4W because of the new technology. The lower power rating of the electricity meters will mean less energy consumption and therefore, a greater energy savings from the lifetime perspective of the meter.
