How is refrigerant charge calculated?
The refrigerant charge is obtained by multiplying the density of gas (ρg) and liquid (ρl) refrigerants by integral along length of the tube. The calculation of refrigerant charge in the low pressure tubes is the same as that in high-pressure tube, which includes the refrigerant charge of A/D (mA/D).
What is DVM Samsung?
Digital Variable Multi System (DVM S) is an advanced cooling and heating system designed for residential and commercial buildings, from large high-rises to smaller shops.
How is VRF calculated?
The criteria for a unit to be a VRF is having several indoor air-handling units and one outdoor condenser or compressor. That means that if you have a 10 ton condenser unit with 13 indoor units each 1 ton, then your diversity factor is 130%. That means that you have 30% more capacity in evaporation than condensation.
What is DVM HVAC?
DVM (digital variable multi), inverter-driven, and other VRF systems allow for one outdoor unit to serve multiple indoor units (up to 16 with DVM).
What is VRF HVAC?
Variable Refrigerant Flow (VRF) HVAC systems consist of outdoor units connected to multiple indoor units via refrigerant piping to provide cooling and heating to individual zones.
How do you calculate kW and TR?
Electric motor driven chillers are rated in kilowatts per ton cooling.
- kW/ton = 12 / EER.
- kW/ton = 12 / (COP x 3.412)
- COP = EER / 3.412.
- COP = 12 / (kW/ton) / 3.412.
- EER = 12 / (kW/ton)
- EER = COP x 3.412.
