液压油冷却器

选择正确的换热器对于确保池水快速加热到所需温度非常重要。确定游泳池换热器尺寸时要考虑的主要问题有:

1. Pool size – what is the water capacity? Heat exchangers are sized according to capacity, so a unit designed to heat a 80 m³ (18,000 gal) pool would be no use, if you have an 180 m³ (39,500 gal) pool.
2. 怎样加热池水？通常选择锅炉或可再生能源进行加热。如果采用的是可再生能源，请选择专为太阳能电池板或热泵加热低温水而设计的换热器，因为这些设备将游泳池加热到所需温度需要的能量较少。
3. Boiler water temperature – however, most pools will be heated by boilers, so what is the temperature of the boiler water? Usually, it’s between 80 °C and 85 °C – the ideal temperature for pool heating. Some boilers are lower – around 60 °C. So, using 82 °C water, a heat exchanger providing 110 kW should heat your 180 m³ pool efficiently. But if the boiler water temperature is only 60 °C, the heat available to transfer drops to around 60 kW – a reduction of over 40%, so a larger heat exchanger would be required for the pool to achieve full temperature.
4. What are the water flow rates? Flow rates are vital for the heat exchanger to transfer thermal energy to the pool. If the hot water flow rate is too low, the available energy will not be passed through the heat exchanger. However, the flow rate of the pool water is equally important. People often think it is important to generate a large temperature differential between the pool water entering and leaving the heat exchanger. They are happy, if the pipework connected to the outlet of the heat exchanger is noticeably warmer than it is at the inlet. In reality, this actually reduces the efficiency of the heat transfer process! This is because the pool water flow is too low – the water remains in the heat exchanger for too long, so a much smaller volume of water is being heated to a slightly higher temperature. 然而，在池水的流速增加后，换热所需的时间就会减少，即使通过换热器的池水温度仅略微升高（例如1.5°C），也会对整个池水的加热效率产生更大的影响。
