Through the scheme of the utility model, the control cabinet 4 is a PLC control cabinet for calculating and controlling the water yield.
The implementation method comprises the following steps: segmenting the interval according to the annual maximum water temperature Tmax and minimum water temperature Tmin, if the interval is divided into n segments, then the interval temperature difference,
when the water inlet temperature of the water inlet connecting flange 2 measured by the temperature sensor 3 falls into a certain one of the n intervals, the high-temperature value T of the interval is taken as a reference, the water quantity of the water outlet connecting flange 5 meeting the air outlet temperature requirement is recalculated, and the calculation formula of the water quantity is as follows:
ΔTa＝P/(CaρaQa)
Qw＝P/(CwρwΔTw)
