Problems solved by technology

However, at present, most of the transcritical carbon dioxide experimental systems used in colleges and universities are simple refrigeration systems, their functions are relatively single, and the utilization rate of equipment is low, which has caused a huge waste of resources invisibly; at the same time, scattered and single-function experiments The heat pump system will occupy a large laboratory area; colleges and universities urgently need to integrate single-function heat pump systems to reduce floor space, improve equipment utilization, reduce school waste in experiments, and improve comprehensive utilization of school experimental equipment.

Abstract

The invention discloses a solar-jet carbon dioxide cascade type refrigeration integrated test station. A solar heat collector system provided by the invention comprises a solar heat collector and a generator. A solar jet system provided by the invention comprises a working medium a pump, an injector, a condenser, a solenoid valve 1, a throttle valve 1 and an evaporative condenser. A single-stage carbon dioxide compression system provided by the invention comprises an evaporative condenser, a flowmeter 1, a carbon dioxide gas-liquid separator, a carbon dioxide compressor, a carbon dioxide oil separator, a valve, a carbon dioxide drying filter, a solenoid valve, a throttle valve 2, a refrigerant stop valve 1, a refrigerant stop valve 2, a single type air conditioner, an electric heater, a carbon dioxide finned tube exchanger, a carbon dioxide shell-and-tube exchanger, a flowmeter 2, a water pump and a thermal insulation water tank. According to the technical scheme of the invention, through controlling the on / off state of the refrigerant stop valve 1 and the on / off state of the refrigerant stop valve 2, a simulated solar jet and carbon dioxide single-stage compression cascade type refrigeration system and a solar jet and carbon dioxide single-stage compression cascade type cold water preparation system are realized.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a comprehensive experimental platform for solar energy injection and carbon dioxide cascade refrigeration. Background technique [0002] Solar energy is an inexhaustible, inexhaustible and non-polluting ultra-clean renewable energy, especially in the current situation of high oil prices and aggravated global warming, the development and utilization of solar energy are more and more popular Favored by scholars from all over the world. The combination of photoelectricity and photothermal, solar energy and architecture as a building cooling and heating source are two basic trends in the development of solar energy technology in the contemporary world. However, the conversion rate of solar energy utilization is only 10%-12% at present, so the utilization of solar energy is often combined with other systems for comprehensive utilization, so as to significantly improve the utilization rate an...
