With the improvement of environmental protection and energy saving requirements, the use of coal-fired boilers continues to reduce, some areas without municipal heating, with more and more air source heat pumps, air source heat pumps supporting plate heat exchanger selection needs to pay attention to what issues?
Air source heat pump supporting plate heat exchanger is the main feature: the high temperature side of the supply and return water temperature is low, the air source heat pump energy efficiency is relatively high state can provide hot water temperature at 48 ?, and then increase the temperature, energy consumption is too high, not economic. Therefore, the heat pump is used as the heat source of the heating method to floor heating, the main operating conditions for the use of the primary side of the supply and return water temperature of 48/38 ?, the secondary side of the supply and return water temperature of 45/35 ?. Its main characteristics are small logarithmic temperature difference and large flow rate.
If the heat exchange equipment is not good heat transfer, will not reach the secondary side of the water supply temperature, but also improve the energy consumption of the heat pump; with the aspect ratio is too large, the deep wave is too shallow plate will cause the resistance of the first and second side is too small, the head of the circulation pump is too high, but also cause excessive consumption of energy. This requires a comprehensive consideration from two aspects of heat transfer and pressure loss to select the most suitable plate type to meet its special working conditions.
Qingdao Reapter for air source heat pump supporting plate heat exchanger has many years of design, manufacturing, operation experience, and a very large number of plate type, can be from a one-time investment, safe and reliable operation and freight costs and other aspects for your consideration, to provide you with high quality, saving, good products.
