The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).
New York City law regulates the safety of space heaters. Space heaters for sale in the city must have a thermostat to control temperature, an automatic shut-off feature if the heater tips over or overheats, and must be certified and labeled by a nationally approved organization or laboratory. [15]
Space heaters also have a hidden hazard: They can cause overheating — aka hyperthermia — especially in kids, people with disabilities and older adults who may have difficulty leaving a room ...
Heat sinks function by efficiently transferring thermal energy ("heat") from an object at high temperature to a second object at a lower temperature with a much greater heat capacity. This rapid transfer of thermal energy quickly brings the first object into thermal equilibrium with the second, lowering the temperature of the first object ...
Whether you need a space heater for supplemental heat or as a backup when your central heating fails, you can safeguard your home by following a few guidelines. 1. Choose the Right Location
Part of the water is evaporated, absorbing the sensible heat from the air and increasing its relative humidity. The air dry-bulb temperature is decreased but the wet-bulb temperature is not affected. [15] Similar to the fogging system, the theoretical limit is the wet bulb temperature, but performance of the evaporative cooler is usually around ...

Under this control sequence, the same cooling maximum airflow is selected and is similarly lowered as the space temperature decreases. By the time the space temperature drops to the cooling temperature setpoint, the airflow reaches a lower minimum value than that used in the "single maximum" sequence (10% - 20% vs. 30% - 50% of maximum cooling ...
