فيديو شرح VRF Systems Explained - Variable refrigerant flow basics HVAC ضمن كورس التبريد والتكييف (HVAC) شرح قناة The Engineering Mindset، الفديو رقم 7 مجانى معتمد اونلاين
VRF System basics, understand the different types of VRF VRV systems and the basics of how they work in the HVAC industry.
See the ETS 5M in 3D https://bit.ly/3nc5s4m
The ETS 5M ensures low acoustic level and offers full performance bi-flow capability-enabling quiet, precise performance for both cooling and heating.
In addition, the ETS 5M is ideal for high evaporating temperature Computer Room Air Conditioners (CRAC) with direct expansion.
