谷物冷却中风量与进风、出风焓差的乘积即为谷物冷却机的制冷量。空气焓差反映谷物冷却机冷却每立方米空气的能耗,在谷物冷却机制冷量一定的情况下,空气焓差越大,则谷物冷却机的送风量越小,反之则越大。影响焓差的因素是进风和出风温差,以及湿空气的湿含量变化,而在制冷降温过
The product of the cereal cooling stroke volume and the inlet air flow and the outlet air enthalpy difference is the cooling capacity of the grain cooler. The enthalpy of air enthalpy reflects the energy consumption per cubic meter of air cooled by the grain cooler, and the larger the enthalpy of air enthalpy is, the smaller the amount of air enthalpy of the grain cooler is, and vice versa. The factors that affect the enthalpy difference are the temperature difference between the inlet air and the outlet air, and the change of the moisture content of the humid air,
