SEA Solar Thermal Technologies/Products Development

SEA's pipeline of new solar thermal application in development is leading the solar thermal technology/application in the industry, focusing on a broad range of solar thermal energy needs. SEA Groups historically has invested more than 8% of its total revenue annually in the research and development of new products across all temperature range of solar thermal application. Relying on the strength of its pipeline and scientific talent and technical strength, SEA has generated a steady stream of breakthroughs over the years. And now, with its patents granted both in US and in the World, the Company has broadened its pipeline to include more promising solar thermal products both in normal temperature and high temperature applications in areas such as Sky-window Collectors,  Solar Air Conditioning, Distributed CSP energy generation, Automation Production Line for all glass vacuum tube manufacturing, Solar Thermal Meter, Solar System Over-heating Control, etc. areas. SEA Groups Ltd. researchers continue to work to ensure the best solar thermal products for our customers in the years to come.

 

US Patented Solar Water Heater System

This proprietary technology gives an effective and efficient method to change any existing gas, electrical or propane water heater into solar water heater meeting normal hot water usage needs.

The retrofitting is easy to achieve with basic plumbing skills, and the retrofitted solar water heater still use the gas/electrical as backup heating energy, while using above 75% of solar energy to heat the domestic hot water depending on the location where the systems were installed.

The retrofitting kit for regular house is available now, building owner can spend a weekend retrofitting gas/electric water heater into solar water heater and starting save environment immediately.

Sky-window Collectors

SEA Groups Ltd has developed second generation solar thermal collectors with patent technologies. The solar thermal collectors looks and shapes will be just like regular "sky-window" or "regular window", and could be installed like sky window or normal window. The Sky-window collectors will provide feasible products for promoting solar thermal application be widely accepted or applied to all buildings, increasing renewable energy usage, and reducing carbon emission. These window-type solar collectors will have high efficient transition rate, and suitable for any kind of environment: cold and warm.

SEA Groups will manufacture its second generation solar thermal collector in US as soon as the Market is adjusted.

 

Solar Air Conditioning

Solar air conditioning refers to any air conditioning (cooling) system that uses solar power, which includes solar air conditioning using desiccants, passive solar cooling, solar thermal cooling and photovoltaic (PV) solar cooling.

SEA focus on solar thermal application, so its research and development in solar air conditioning using the solar thermal cooling technologies.
Innovative hot water solar thermal energy collectors are developed by SEA providing the clean and free energy heat source for the cooling chiller units.

Solar thermal cooling

Active solar cooling uses solar thermal collectors to provide thermal energy to drive thermally driven chillers (usually adsorption or absorption chillers).  The solar thermal collector, for example, provides solar thermal heat by concentrating the sun’s energy on a collection tube and heating the recirculated heat transfer fluid within the system. The generated heat is then used in conjunction with absorption chillers to provide a renewable source of industrial cooling.

There are multiple alternatives to compressor-based chillers that can reduce energy consumption, with less noise and vibration. Solar thermal energy can be used to efficiently cool in the summer, and also heat domestic hot water and buildings in the winter. Single, double or triple iterative absorption cooling cycles are used in different solar-thermal-cooling system designs. The more cycles, the more efficient they are.

Efficient absorption chillers require water of at least 190 °F (90 °C). Common, which SEA's heat-pipe vacuum tube collector could achieve, while those inexpensive flat-plate solar thermal collectors only produce about 160 °F (70 °C) maximum temperature hot water.

A pilot project was done using all glass vacuum heat-pipe vacuum tube solar collector system for testing solar air conditioning.  

 

 

SEA Multi-functions Solar Thermal System Controller

With years of experience in the solar thermal application industry, SEA has developed the multi-functional solar thermal system controller, which resolved obstinate issues, such as collector frozen, overheating, etc., that have hindered the substantial usage of solar thermal application.

Current SEA controller provide functions to overcome collector frozen, collector/ system overheating, multi-systems control, solar thermal energy monitor, solar thermal flow recording, etc. and the Company is constantly improve its system and system control function to meet the efficiently and effectively apply for solar thermal energy goal.
