Solar Powered Booster Jet Refrigeration System

Abstract

The invention discloses a solar-powered booster injection refrigeration system, which relates to the field of refrigeration systems. In the existing solar booster injection refrigeration system, the heat exchange temperature difference of the intermediate heat exchanger is large, which affects the further improvement of the system performance, and there is a large amount of irreversible throttling losses. The invention includes a solar collector, a first water pump, a hot water storage tank, a second water pump, a generator, a steam ejector, a condenser, a working fluid pump, a two-phase ejector, a gas-liquid separator, an expansion valve, and an evaporator , scroll compressor. The scroll compressor is installed at the inlet of the two-phase ejector, which can effectively increase the inlet pressure of the ejecting fluid, realize the recovery of throttling loss, increase the inlet pressure of the secondary fluid of the steam ejector, improve the performance of the steam ejector, avoid malfunction, and improve the performance of the steam ejector. Solar energy utilization and system operation stability, scroll compressor, steam ejector and two-phase ejector jointly undertake the refrigerant compression, reducing power consumption and improving system energy efficiency.

Description

technical field [0001] The invention relates to the field of refrigeration systems, in particular to a solar-powered supercharged jet refrigeration system. Background technique [0002] At present, vapor compression refrigeration systems are widely used in refrigeration and air conditioning, but mechanical compression refrigeration systems driven by electrical energy consume too much fossil energy and cause many environmental problems. Energy and environmental problems are becoming more and more serious, and people are turning their attention to refrigeration systems that utilize renewable energy sources, such as absorption, adsorption and ejection refrigeration systems. [0003] The ejector refrigeration system has a simple structure, reliable operation, low cost and maintenance cost, and can effectively compete with the complex and expensive absorption refrigeration system when the heat source temperature is lower than 80 °C. Solar energy is a clean and renewable energy s...
