Heat Pump Operating Cost Formula:
The Heat Pump Operating Cost (HPOC) refers to the total energy cost required to operate a heat pump over a specific period. Heat pumps are devices that transfer heat from one location to another, commonly used for heating or cooling residential and commercial spaces. Unlike traditional heating methods that generate heat, heat pumps move heat from the air, ground, or water to maintain a desired temperature inside a building. The energy consumed by the heat pump is a major factor influencing the operating cost.
The operating cost of a heat pump depends on several variables, including the heat pump’s power rating (HP), the energy cost per unit of electricity (EC), and the time the heat pump is in operation (T). The formula for calculating the HPOC allows for determining the energy cost based on these inputs.
The energy consumption of a heat pump is typically measured in kilowatts (kW), and the cost of electricity is often given in kilowatt-hours (kWh), representing the amount of energy consumed over time. By multiplying the power rating, electricity cost, and operating time, you can determine the total cost of running the heat pump.
Heat Pump Operating Cost, HP in currency units is calculated by the power rating of the heat pump, P(W) in Watts then divide it by 1000, and multiply by Energy cost per unit, E, Time the heat pump operates, T in hours.
Heat Pump Operating Cost, HP = (P(W) / 1000) * E * T
HP = heat pump operating cost in currency units.
P(W) = power rating of the heat pump in Watts, W.
E = energy cost per unit (e.g., cost per kWh of electricity).
T = time, the heat pump operates in hours.
Heat Pump Operating Cost Calculation:
1. A heat pump has a power rating of 3000W (3kW), the cost of electricity is $0.12 per kWh, and the heat pump runs for 8 hours a day. Calculate the operating cost.
Given: P(W) = 3000W, E = $0.12 per kWh, T = 8hrs.
Heat Pump Operating Cost, HP = (P(W) / 1000) * E * T
HP = 3000 / 1000 * 0.12 * 8
HP = 3 * 0.12 * 8
HP = $2.88per day.
2.A heat pump has a power rating of 2000W (2kW), and the operating cost is $5.00. The energy cost is $0.10 per kWh. Calculate the time the heat pump was operating.
Given: P(W) = 2000W, E = $0.10 per kWh, HP = 5.
Heat Pump Operating Cost, HP = (P(W) / 1000) * E * T
T = HP / (P(W) / 1000) * E
T = 5 / (2000 / 1000) * 0.10
T = 5 / 2 * 0.10
T = 25hrs.
