LOW-COST, ENERGY-SAVING, FLOODED-EVAPORATOR-TECHNOLOGY
Thermostatic Flow Controller (TFC) is a new, flooded-evaporator-technology, usable for all sizes of plants and all refrigerant, except those with big temperature glide. The flow to the evaporator is controlled by the receiver pressure, which is controlled by a heat exchanger – without any moveable parts.Compared to a Thermostatic Expansion Valve the other components, especially the evaporator, are exploited better, improving the Cost-Benefit relation.TFC is robust, reliable and don’t need service, and can be placed at inaccessible places.For small cooling and frost application the heat exchanger is just a small tube, which also acts as receiver. The amount of circulating refrigerant automatic adjusts to current condition and the application can be moved freely between cold and warm location.A flooded evaporator increases cooling effect and COP, and for most refrigerants the heat exchanger does the same, in all the COP increase 8-17%, depending on the type of refrigerant.The improvement comes from a more efficient cooling circuit and adds to all other energy saving measures.According to ⅡR the wold use 15% of all produced electrical energy for cooling and air-conditioning.Reducing this by 8-17% equals 1-2% of all electrical energy- corresponding to several big power plants-and that’s without extra use of other resources.TFC is tested thorough for several years, in polar and tropical territories, for cooling and frost applications, and for small and big cooling effect (100W–40kW).
