ADVANSOR’s products

compHEAT: CHP – combined heat and powerAdvansor develops heat pump solutions dedicated to power plants operated by either gas motor or gas turbines.The heat pump produces hot water up to 90°C which enables direct pipe connection to the external pipe work with no interference with the motor and piping.

compBINE: Combined heating and coolingCombined heating and cooling - produce hot water up to 100°C and get ice water for free or counter wise. Advansor’s product line is highly suitable in connection with pasteurisation, CIP systems and other application in food industry where coinciding demands for heating and cooling exist. Combined heating and cooling saves both capital investment and energy cost.

compFORT: Chiller applicationsAdvansor offers highly compact water cooled chillers in the range from 100 to 400 kW. With natural refrigerant, no toxic risk and no flammability this is a safe and economical feasible choice.

compSUPER: Refrigeration applicationsAdvansor offers refrigeration systems (compressor rack’s) for supermarkets and other commercial/ industrial applications. The units work with as the only refrigerant. Main focus are placed on reliability, ease of service and low energy consumption.

Karakteristika for CO2Generelle egenskaber:

� Gruppe II (L1) med ODP = 0 + GWP = 1 (NH3 = L2, R290 = L3)

� Ingen begrænsninger på opstillingssted og anvendelse

� Temperatur og trykområde: -55 -> +31°C (5.5 -> 73 Bar)

� Tungere end luft, i det hele taget en ”tung” gas

Fordele:

� Små rørdimensioner og små tryktab

� Bedre virkningsgrader på kompressorer og høj volumetrisk kølekapacitet

� Bedre varmeovergang – specielt ved ”pool-boiling”

Udfordringer:

� Højere tryk (op til 130 bar)

� Høje stilstandstryk

� Anvendelse af sikkerhedsventiler

� Udskilning af olie/ væske-dråber fra CO2-gassen

� Sikring af anlæggets COP ved høje temperaturer

� Pris på komponenter

CO2
