AI Technical Summary

Benefits of technology

The invention provides a solar-thermal system that includes a generator, evaporator, heat pump ejector, and condenser components. The generator component produces a vapor stream, which is then fed into the ejector heat pump. The heat pump extracts heat from the vapor stream and uses it to cool the mixed flow of air. The technical effects of this invention include improved efficiency and utilization of solar energy for energy production.

Problems solved by technology

One of the challenges of ejector heat pumps is that its coefficient of performance (COP) is lower than that of a mechanical compressor-based heat pump.

Abstract

In one embodiment, solar-thermal system is provided. The solar-thermal system comprises a generator component; an evaporator component; a heat pump ejector comprising a mixing chamber; said heat pump ejector coupled to the generator component and the evaporator component; wherein the generator component emits a vapor stream into said mixing chamber and the heat pump ejector is configured to extract a working fluid vapor from the evaporator component into said mixing chamber through entrainment thereby to form a mixed flow; and a condenser component configured to cool said mixed flow via a cooling loop.

Description

FIELD[0001]Embodiments of the invention relate to heating and cooling systems.BACKGROUND[0002]Ejector heat pumps (EHPs) are a decades old technology that was and is applied to refrigeration and air conditioning applications. The common principle behind so-called Rankine refrigeration cycles is that a working fluid (i.e. the refrigerant) can be used to move heat from a lower temperature location to a warmer external environment by compressing the working fluid to raise its temperature above the external environment and subsequently expanding it to drop its temperature to provide the cooling effect. EHPs operate on this principle utilizing a vapor ejector with no moving parts to compress the working fluid instead of a mechanical compressor.[0003]Referring to FIG. 1, a diagram of an exemplary ejector for a heat pump is shown 100. The ejector 100 includes a supersonic nozzle 102. In use, a primary (supersonic) vapor flows 104 into the nozzle 102 where it undergoes expansion. A secondary...
