Do VCR systems use a lot of electricity?
In VCR systems where a refrigerant is circulated to achieve cooling, a substantial amount of high grade energy is required to run the compressor. Further, the traditional VCR machines are leading electricity consumers, accounting for approximately 16% of the total electricity consumption by building sector 2020.
What are the components of a VCR system?
VCR systems mainly consist of an evaporator, condenser, compressor, expansion valve, controller, and refrigerant . Although the VCC is considered one of the most efficient thermodynamic cycles ever made due to its high coefficient of performance (COP), it still accounts for the most significant portion of energy consumption in buildings.
What is vapor compression refrigeration (VCR)?
In today’s world, the vapor compression refrigeration (VCR) system plays a vital role in global energy consumption across diverse applications such as climate control, refrigeration, and food preservation. This extensive energy usage emphasizes the need for sustainable and energy-efficient solutions to reduce our reliance on electricity.
What is a direct solar VCR system?
In direct solar VCR systems, termed as PV-assisted VCR systems, where photovoltaic cells convert solar energy into electricity by means of photoelectric effect is used to drive the compressor of VCR cooling systems.
How solar energy can be used for VCR cooling system?
The combined flow is then pumped back to the thermal storage tank. Solar energy can be used for the refrigeration through Photovoltaic Electric Conversion (PVEC), thereby producing electricity which can run the compressor of VCR cooling system. The word ‘photovoltaic’ combines two terms—‘photo’ means light and ‘voltaic’ means voltage.
Why are VCR systems work consuming devices?
Therefore, this device has to be powered externally to transfer heat in the opposite direction and hence, the VCR systems are work consuming devices. The VCR systems employ a working fluid called the refrigerant which is pushed through the system and undergoes a phase change from liquid to gas and vice-versa.
