GRD means Grille, Sign up and Diffuser. GRD signifies a ingredient is either a grille, a register or perhaps a diffuser. It's a generic term utilized to explain anything that’s source/return and exhaust/consumption air.
BC means Branch Circuit. BC or BC controller is referring into the controller used in the piping branch unit in a VRF system. It controls the quantity of refrigerant flowing to every circuit based upon the cooling demand from customers.
Keeping optimal humidity ranges is crucial for both comfort and wellbeing. Humidifiers and dehumidifiers support to harmony indoor humidity, which may Have got a direct influence on air top quality.
DHU means Dehumidified Air Managing Device. DHU is designed to eliminate h2o vapor or dehumidify much more effectively than common AHU. It could possibly deploy components for instance desiccant to Increase the dehumidification capability from the system.
Fuel furnaces are a well known option to warmth houses in the colder months, specifically in northern parts with the country. Gas furnaces deliver impressive, dependable warmth to promptly reach the temperature with your thermostat for optimal cost savings and luxury.
The main unit: Traditional HVAC setups encompass Main systems together with central air conditioners, warmth pumps, furnaces, or boilers.
