Air source heat pump heating has obvious advantages in energy saving and environmental protection. Air source heat pump can not only be used as a decentralized heating source, but also as a central heating source.
For the end equipment of the heat pump heating system, there are three types that are used successfully. They are floor heating, radiators and fan coils. These three heating methods have different characteristics and should be selected according to the building function and the use characteristics. In the past, many thought that floor heating and air source heat pumps were the best match, but with the development of technology, radiators and fan coils also showed their own advantages.
The three end devices have different requirements for the temperature of the heat medium. The COP value of the heat pump is related to the output temperature. The higher the output temperature is, the lower the corresponding COP value is. For the floor heating system, it is considered that the best match with the air source heat pump is because It requires the heat medium temperature suitable for the heat pump operating characteristics. Radiator heating is considered to require a higher heat medium temperature. For the actual operation of northern heating, the heating parameters can be determined based on the heat source conditions. The research on low-temperature heating of the radiator shows that: 60°C/45°C is technically economically reasonable and feasible. The temperature of the hot water from the air source heat pump can be completely reduced to the supply temperature of domestic hot water.
The addition of heating facilities to existing buildings is best combined with the renovation of the rooms, as the addition of heating facilities has greatly changed the use of existing buildings, especially considering comfort and economy. Heating devices should be added to existing buildings. Attention should be paid to heat transfer between buildings. For additional floor heating, the structural load bearing and furniture shielding should be considered to affect heat dissipation. Heating of radiators should be taken into account. , and consider whether all rooms need heating.
At present, the use of air source heat pump heating in cold regions has basically reached consensus. Our national heating period is to enter the heating period when the average daily temperature is lower than or equal to 5°C. An ultra-low temperature air source heat pump should be used in severe cold areas. It can be used to provide heating load during the heating period and be coupled with other heat sources during the coldest period. Complementary operation. When arguing for a technical economic plan, consider the energy efficiency ratio of the entire heating period in your area.
Severe haze in winter in the north is basically at the beginning of heating. At this stage, the atmospheric pressure is low, which is not conducive to the diffusion of particles. At this stage, the air temperature is conducive to the operation of the air source heat pump. Therefore, the use of air source heat pump heating in stages in severe cold areas has practical significance for energy conservation and emission reduction, and for improving haze environment.

Since 1998, in the field of mechanical seal work and control, we have made step-by-step efforts to overcome the limitations and difficulties of the factors that affect the stability of the sealing performance, such as the material and the shape of the sealing lip.
Since 2000, continuous improvement and optimization of polyurethane elastomer materials and research on mixing with different materials and chemical raw materials. While the physical properties are balanced, new material performances after different chemical mixtures are also deeply developed.
Regarding the mixing research and development of nitrile rubber, hydrogenated nitrile rubber, silicone rubber, fluorinated rubber and various metal powders, countless deployment tests have also successfully realized the ideal special sealing material.
In the development and improvement of polyamide (nylon resin), polytetrafluoroethylene, and phenolic resin, we also ushered in a rapid increase in the number of our European customers and a doubled increase in sales in the Asian market.
We are researching dust seals (DKBI), piston rod seals (IDI, IUH, HBY), support rings (KZT,), piston seals (OUH, SPGO) in conventional hydraulic sealing systems day after day ), anti-wear rings/anti-wear rings (WR, SPGW) and are suitable for all kinds of jib cylinders, cantilever cylinders, bucket cylinders, lifting cylinders, and power steering cylinders.
Including the research and development and iterative production of the sealing ring of the hydraulic breaker, there have also been more new breakthroughs.
Thank you very much for your attention. If you have any demand for sealing system solutions, please be sure to contact me. I will cooperate with you in an honest and professional manner.
