Tumble Dryer
Heat Pump
BASELINE – WITHOUT DEVICE
At the core of a tumble dryer heat pump is the compressor, which drives the vapor-compression refrigeration cycle. The efficiency of the system is heavily dependent on compressor performance. Scroll and rotary compressors are commonly employed due to their compact form, reliability, and ability to operate efficiently under the moderate pressure ratios typical of dryer applications.
The testing and monitoring devices used show a minor difference in readings. This is due to the accuracy of the testing devices. The SPC Pro 2 only accurately logs from 2A and above, thus testing on this device is prone to processor jitter and not fully accurate. The KWH meter is accurate – as it has a range from 0 – 10A – however it does not data log.
Energy (kWh)
A kWh, or kilowatt-hour, is a unit of energy that measures the amount of electricity or gas a household consumes. It is calculated by multiplying the power an appliance uses (in kilowatts, kW) by the time it runs (in hours).
Power (kW)
A kWh, or kilowatt-hour, is a unit of energy that measures the amount of electricity or gas a household consumes. It is calculated by multiplying the power an appliance uses (in kilowatts, kW) by the time it runs (in hours).
Power Factor
A kWh, or kilowatt-hour, is a unit of energy that measures the amount of electricity or gas a household consumes. It is calculated by multiplying the power an appliance uses (in kilowatts, kW) by the time it runs (in hours).
Current (amps)
"Current amps" means electric current, which is the flow of electric charge measured in amperes (A). Amps (short for amperes) indicate how much charge is flowing per second.
Voltage
Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as powering an electric motor.
CO2 Emissions
CO2 emissions is the amount of CO2 released in the production of each KWh and is currently at 162g CO2 per Kwh produced. Graph indicates how much CO2 is produced to run the motor.
Apparent Power (kVA)
Apparent power is the total power that appears to flow in an AC circuit, calculated as the product of the RMS voltage and current (Vrms * Irms). Measured in volt-amperes (VA), it represents the combination of real power (the useful power that does work) and reactive power (the power needed to support electromagnetic fields in inductive or capacitive components).
Reactive Energy (kVArh)
Reactive energy (or reactive power) is the energy required to establish and maintain the electric and magnetic fields in inductive and capacitive devices within an AC power system, without performing actual work. It is measured in kilovolt-ampere reactive hours (kVArh) or kilovolt-amperes reactive (kVAR) for power.
