Introduction to heat recovery

Heat recoveryisa technology thatappliesa recovery devicetopartiallyorcompletelyrecovertheheat energy generated by the unit during the cooling process,andusesitto providecustomerswith free hot waterof 4 5 ~ 6 5 ^ { \circ } \mathbf { c } . It is suitable for use in large public institutionsand placessuchas hotels,hospitals,and schools.One machine for two purposes,eco-friendly and energy saving.

Having been in theresearchand applicationof heat recoverytechnologyfora longtime,H.Stars Group hasaccumulatedextensive experience in heat recycling,andhasitsownnational patentof heat recovery.Applicationofthetechnologyinprojects providescustomerswith free hotwater,savingalot ofhotwater costs.It reducesthermalpollution to the environmentcausedbycondensation heat,andat the same time lowers the operatingcosts,aswell as the noise of the cooling tower.

Introduction to heat recovery

Introductionto VSD system

VSDunit ismade byaddingavariable-frequency drive toan existingunit,which can realize operation ofthecompressoratdifferent frequencies.This technologygreatly improves theenergyeficiencyof theunit during partial load operation,making it highly efficient intermsof bothcoefficientofperformance (COP) and integrated part load value (IPLV).

Precise temperaturecontrol

Thewatertemperaturecanbecontrolledwithan accuracytoleranceof ± \ : \ : 0 . 3 \ : degrees,meetingthe requirementsof high-precisiontemperaturecontrol.

Low startup current

VSDscrew units offer soft start function to reduce theimpact of starting current;the frequency convertercomeswithaDC reactorthatcanminimize harmonic interference;andthereisalsoanoptional low harmonic filter which,under the input power of thefrequency converter,isin linewith IEEE-519 specification for harmonicdistortion,and equipped withfunctions of harmonic filter over-temperature protection and capacitorswitching.
