1. The safety margin of the high-speed press area should not be too large, that is, it should not exceed 10% of the calculated value.
2. The water output in the fan coil unit should not be too small. If the situation deteriorates, it is recommended that the total flow should not be less than 0.115m/s.
3. When using variable flow monitoring, check and calculate the outdoor 0°C condition.
4. When the hot substance of the punching needle is steam, the installation position of the steam trap should be more than 300mm away from the Duyu punching needle, and the intelligent return water should flow from the punching needle to the water storage tank.
5. The fluidity direction of the hot material of the punch should be parallel to the fluidity direction of the gas, but the current fluidity direction of the thermal material is mostly the opposite of the gas fluidity direction of the household punch. This is of course good for the heat exchanger, but not for freezing, especially when the hot substance is water, which is more prone to lock-up at lower temperatures.
6. In severe cold areas, the cooling and heating of the fresh air module cannot use a set of fan coil units at the same time.
