Final answer:
Power resources in industrial and commercial contexts refer to energy consumption by appliances and equipment other than those used for space conditioning or occupant comfort. These include high-energy devices like refrigerators and dryers, and managing their use can lead to significant energy savings. Understanding how power, energy, and time interrelate helps in estimating operational costs and identifying efficiency measures.
Step-by-step explanation:
The ASHRAE definition provided in the question pertains to the consumption of power resources that are used in manufacturing, industrial, or commercial processes, which do not include conditioning spaces or maintaining comfort for building occupants. These power resources often encompass the operation of major equipment such as refrigeration units, cooking appliances, and clothes washing facilities. It is highlighted that devices with the primary function of generating heat or cooling require significant energy, and thus, are 'power-hogs' such as clothes dryers, water heaters, and space heaters. Meanwhile, devices like compact fluorescent light bulbs are examples of more efficient technology, offering greater light output for less power consumption.
Understanding the relationship between power, energy, and time is crucial for estimating the cost of operating these appliances. Reducing either the power of an appliance or the time it is in operation can result in energy savings, which becomes important due to the rising costs of energy. This knowledge allows for strategic decisions in limiting the use of high-power appliances that are in operation for extended periods, which is a more cost-effective method of conservation.
In summary, managing the consumption of power resources in industrial and commercial settings is a complex task that involves considering the power demands of various appliances and the duration of their use, in order to optimize energy efficiency and reduce costs.
