Product nomenclature
New trends of clean energy
In thearea of clean and renewable energy utilization,sewage source heat pump technology can be calleda model of energy saving and emission reduction.In line with world trend of "energy saving,emissionreduction,environmental protection,sustainable development",thistechnologysuccessfully heatsthedomestic water for users through the heat in urban sewage by adopting the heat pump technology.At present, the sewage source heat pump technology iswidely used in Spa,resort hot spring poolsand swimming pools.With the successful implementation of many projects,it has fully proved the advantages of the original sewage source heat pump technology.Comparedwith the conventional heatpump,the energysavingrateof this technologyreaches 3 0 % - 5 0 % ，andhasreallyachievedzeropollutionand zero emissions without any exhaust gas,waste and residue to the atmosphere.Inaddition,the investmentand operating costs of thistechnologyaresignificantly lower than traditional methods. Aftervigorous development,it can save hundreds of millions of tonsof coal each year,whichachievesreally energy conservation andenvironmental protection.
Sewagesource flowratecharacteristics--- largeand stable Sewage source temperature characteristics--- warm in winter and cool insummer.
Eveninseverecold regions,the temperatureof sewageisalso over 10-18 ^ { \circ } { \mathsf C } ,which isa rich heat source;the temperature of sewage in summer is 2 0 - 2 8 ^ { \circ } C ,which is the ideal heat source.
Incomparison withthe initial investmentof traditional heating，coolingand groundsourceheatpumps,the initial investment of sewage source heat pumps is the lowest,and the economic benefits are significant. It recovers the heat energy in the urban sewage,which not only developsa clean energysource,butalso reduces the urbanwaste heat emissions and protects the environment.

Cold Recovery Technology
The principle of cold recovery is based on the principle ofheating，recoveringthecoldthatisreleasedtothe environment and converting it into the air conditioning systemtogeneratecoldwaterfortheairconditioner,it canreplacepartof theoriginalairconditioningsystem load to achieve energy saving effects.
Variable Frequency Drive (VFD) Technology
VFDis to change the power supply frequency, thereby adjusting the load,reducing power consumption, reducing losses,and extending the service life of the equipment.The core of the VFD is the frequency converter,which realizes theautomatic adjustment of the running speed of the motor through the conversion of the power supply frequency,and changes the fixed grid frequency of 5 0 H z to a changing frequency of 30- 1 3 0 mathsf { H z } .Inaddition,it canwiden theadaptable range of the power supply voltage to 142-270V,which solves the problem of the grid voltage instability which can affect the operation of the equipment.The technology thatrealizes AC control by changing the AC frequency is called VFD technology.
