… reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs. At present, the Assembly pays 22 000 SEK for electricity, water and …
… the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump. As the power is a function of the pressure difference over the pump, the pump current correlates to the …

… eye treatment with a lavage system together with a constant rate infusion pump. Procedures ” Three veterinary nurses at ATG: s Hästsjukhus in Skara were asked nine questions at individual interviews. Inclusion criteria for participation in the interview were that the nurse …
Bakgrund/syfte: Sma?rtlindring via PCA-pump a?r en effektiv och sa?ker metod vid postoperativ va?rd. Den syftar till att ge patienten större möjlighet att pa?verka sin sma?rtlindring. Tidigare studier pa?visar att ma?nga patienter upplever sin kunskap om PCA- pumpen som …
An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar …

… för patienter som genomgår hysterektomi. Försöksgruppen erhöll både PCA pump ( patient ?kontrollerad-analgesi) och sårkatetrar och kontrollgruppen erhöll endast PCA pump. En PCA pump är en förinställd smärtpump där patienten själv sköter sin administrering av smärtlindrade …
Möjligheter och konsekvenser för Johnson Pump
Examensarbetet har utförts på Johnson Pump AB i Örebro och behandlar tillverkningen av marina kylvattenpumpar. På den allt mer globala pumpmarknaden har konkurrensen blivit hårdare och Johnson Pump har märkt ökade krav på främst kostnadseffektivitet och leveransprecision …

… I outlined the various proposals. The basic concept was that some kind of pump would build pressure in the liquid and when the user opens the nozzle the liquid will come out without the need to use the mouth to suck. The screening phase consisted of two steps. The first step, a …
This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common …

… från tanken till motorn används på tunga fordon idag vanligen en mekanisk pump, driven av och placerad på motorn. Anledningen till att ha en direktdriven pump är främst att det anses som den mest robusta lösningen för den relativt enkla uppgiften som bränsletransport och liten …
If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building’s exhaust air. The air has a relatively high and constant temperature all year around, leading to a …
Energibesparingsåtgärder vid blekeri 4 & 5 med jämförelse mot ny utrustning
Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves …
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water …
