Air-Conditioners

https://korean-machinery.com///inquirySamsung Wind-Free™ system provides users with the ideal conditions by maintaining the desired room temperature using Wind-Free™ Cooling to gently disperse cold air through thousands of micro air holes. First, the system lowers the room temperature in Fast Cooling Mode and then automatically switches to the Wind-Free™ Cooling Mode once the desired temperature is reached. The Wind-Free™ system has the added ability to connect to Samsung’s Smart Home App. Controlling your comfort has thus never been easier.
The Wind-Free™ unit delivers an air current that is under 0.15 m/s while in Wind-Free™ mode. Air velocity that is below 0.15 m/s is considered “still air” as defined by ASHRAE 55-2013 (American Society of Heating, Refrigerating, and Air- Conditioning Engineers).


Samsung’s circular air wave consistently controls the temperature of the room by providing an even distribution of air across a full 360-degree range. Bladeless flow control allows for a 39 percent increase in coverage area by delivering 100 percent of air volume, compared to traditional four-way cassette units, which can lose up to 25 percent of air volume.
Samsung’s System Air Conditioning units like the 360 Cassette rely on outdoor units to function. But conventional outdoor units are not without their limitations, as many of them take up large amounts of space.
Samsung Electronics has been contributing to and leading the digital revolution by offering its products of innovative technology, original design, convenience and high value, thus not only satisfying current demands of the customers, but also presenting new products that can predict future market demand and lead the global digital market.
The air conditioning sector of Samsung Electronics begun its multilateral business with home air conditioners in 1974 and expanded its boundaries to include EHP products, GHP (Gas engine-driven Heat Pumps), and ERV (Energy Recovery Ventilators). Samsung Electronics is still evolving into a company that offers total air conditioning solutions, by developing cutting-edge digital control solutions to off er customers the best air conditioning services with its wide range of products.

Cleaning Equipment of Refrigerant Pipes

https://korean-machinery.com///inquiry[INQ. NO. 1807M11] It has been announced that a cleaning technology capable of using the existing refrigerant pipes without replacement has been developed.
Bumsuk Engineering has developed a cleaning equipment of refrigerant pipes for the system air conditioner which can use the recovered refrigerant as a cleaning agent.
R22 was the refrigerant of system air-conditioners (multi-conditioners, heat pumps) installed before 2010 in residential complexes, large office buildings, public institutions (schools, libraries, etc.). In cases where an outdoor unit using R22 refrigerant is replaced with a new one using R410a refrigerant, as the existing refrigerant pipe is embedded in a wall or a ceiling, it is often reused as it is without cleaning.
When you use R410a refrigerant for the outdoor unit of newly replaced system air-conditioners, be sure to clean the inside of the already installed refrigerant pipes before reusing it as refrigeration oil or other contaminants are attached to the inside of the pipes.
In the conventional cleaning method, pipes are cleaned by connecting the recovery system and regenerator separately even in case of using either chemical cleaning agent (solvent cleaner) or existing refrigerant. However, mineral oil or residues of acid content existing in the oil cannot be eliminated even by vacuum cleaning over three times; and mineral oil, moisture and acid content are not eliminated even after vacuuming for one week, thereby causing problems such as damage of the compressor.
A spokesperson for Bumsuk Engineering explained, “As all new system air conditioners (outdoor units) use HFC series R410A or R407C (partially imported goods), synthetic oil is used for refrigeration and, as a result, contaminants are generated while the mineral oil passes through the existing pipes. Such contaminants can clog the refrigerant circuit or damage the compressor.”

 

Eliminating impurities by more than 99%

The cleaning equipment of refrigerant pipes developed by Bumsuk Engineering is a single piece of equipment combined with the functions of recovery and regeneration capable of recovering and regenerating the existing refrigerant and uses the recovered refrigerant as a cleaning agent.
A spokesperson for Bumsuk Engineering added, “We obtained a patent for ‘Cleaning equipment for refrigerant pipes in air-conditioners and its cleaning method’ by automatically controlling pressure, temperature and electronic valve with technology of inside of pipe cleaning by using the refrigerant (R22) recovered from the removed system air-conditioner. The patented refrigerant pipe cleaning equipment is a technology-cum-equipment that removes more than 95% of impurities such as oil attached to pipes by cleaning 40 meters of pipes connected to indoor unit for about 20 minutes.”
It is possible to extend the service life of the outdoor unit by eliminating the cause of its failure through cleaning when the equipment is replaced with a new one. By reusing the pipes, you can expect saving of installation costs and work time as well as reduction of waste. Especially, as the cost for removing the refrigerant pipes installed in both the outer and inner walls and the roof is not required and the pipes are reused, you can reduce costs drastically.
