PRINCIPLEOFTWOSTAGEEVIDCINVERTERSTEAMHEATPUMP

Thecascade technology adopts atwo-stagerefrigerantcirculationsystemwith intermediate couplingheat exchange mode,coupling thecondensation of thefirst stage and the evaporation of the second stage to achieve energy exchange between the first and the second stages.Meanwhile,it reduces the compressionratio of the first stage system and the second stage system, lowers the condensation pressure ofthe first stage system, and enhances the evaporation pressure of the second stage system. The first stage system uses the R32 refrigerant EVI variable frequency system, and the second stage system uses the R245fa fixed frequency system.

APPLICATIONOFTWOSTAGEEVIDCINVERTERSTEAMHEATPUMP

Since its inception, heat pumps have mainly been applied in the civilian sector. In fact, in China, the industrial sectoraccountsforapproximately 70% of the country'stotal energy consumption.Withtheincreasingenvironmental protectionrequirements ofthestate and the continuous riseintheprices oftraditionalenergy sources,the adoption of clean energy and energy conservation and consumption reduction have become important projects forevery enterprise.Compared with direct electricheating,heat pump technology is 3to 4 times more efficient.At current coal prices,itcansave 20% to 40% compared to burning coal.Therefore, using heat pumps to replace traditional energy sources is the most ideal equipment forenergy conservation and consumption reduction foreach enterprise. With the continuous improvement of heat pump technology, the 125°\mathsf{C} high temperature steam heat pump launched byMaconassignificantlyexpanded the applicationof heat pumptechnologyintheindustrial sector.It can be said that most traditional energy sources can be replaced by heat pumps.

Table of EconomicBenefits of Energy-SavingRetrofits

Based on the daily steam consumption of approximately 3 tons (steam heat pumps have an average energy efficiency of2.2 per year),the energy consumption and operating costs are calculated as follows: Steam is produced by recovering heat.When producing 3 tons of steam per day,the average COP of the heat pump is 2.2.

Conclusion:Usinga 125°\mathsf{C} hightemperaturesteamheat pumptoproducesteamforenergy-savingretrofitscan save ￥273,000(\~$37701.16) per year compared to an electric boiler, and the investment can be recovered in only 1.2 years.
