Bernoulli heat pump having laminar flow of refrigerant
An improved Bernoulli heat pump, wherein the intake section of a Venturi tube is structured so that when the refrigerant flows from the intake section into and through most of the middle (narrow) section, its flow is essentially laminar. Additionally, a second, bi-phase, component is added to the flowing gaseous refrigerant. Part of the bi-phase component evaporates, reaching super saturation, which state is maintained in the middle section, owing to the laminar flow, increasing heat absorption.
1. A Bernoulli heat pump, for transferring heat from a heat source to a heat sink, comprising —
a Venturi tube, including a converging intake section, a narrow middle section, and a diverging exhaust section, all interconnected co-axially about a longitudinal axis of the Venturi tube and in tandem, the middle section being in thermal communication with the heat source, and
a blower, disposed at an exhaust end of the exhaust section and operative to cause a refrigerant to flow through the Venturi tube,
an upstream end of the intake section and a downstream side of the blower being in fluid communication with the surrounding atmosphere and said refrigerant including air;
wherein said Venturi tube further includes one or more nozzles, disposed at the intake section and operative to spray a bi-phase fluid into air flowing therethrough and
wherein the heat pump further comprises —
a precipitation tank, disposed in the refrigerant flow path downstream the exhaust section and configured with a bottom to accumulate precipitated liquid, and
a liquid feed tube, one end of which is fluidly connected to the bottom of the precipitation tank and a second end of which is directly or indirectly in fluid communication with any of said nozzles.
2. The heat pump of claim 1 , wherein said bi-phase fluid includes a non-aqueous fluid, the heat pump further comprising —
a fluid extraction box, disposed in the refrigerant flow path downstream the exhaust section or the blower and including porous material operative to absorb or adsorb non-aqueous fluid from the refrigerant and
means for flushing extracted non aqueous fluid from the fluid extraction box to the bottom of the precipitation tank.
