HVAC VS HVDC - MD

HVAC Industry/HVAC Jobs in MD

Most of us know that HVAC or HVACR stands for heating, ventilation, and air-condition/refrigeration. We are familiar that HVAC/R technicians set up, maintain, and fix heating, air conditioning and refrigeration systems. HVAC technicians can also consider studying on only one type of commercial system, for example, they can choose to become a heating, air-conditioning or refrigeration specialist.

What is HVDC?

HVDC represents a high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electric superhighway). Although HVAC and HVDC sound similar, HVDC system has no direct relation to the HVAC/R systems.

High-voltage direct current electric power transmission system handles direct current for the enormous transmission of electricity, unlike the more common alternating current (AC) system. HVDC is less expensive and incurs lower electrical losses especially during the long distance electrical transmissions. HVDC is used in underwater power cable - power transmissions as it avoids the use of heavy currents required to charge/discharge cable capacitance on each cycle.
