An open loop system has no feedback. So if you had a resistance heater with an on/off switch and no thermostat it would just continually supply heat without regard to the temperature of the room. To stop the heat you would turn it off. In essence you become the feedback.

Imagine a room with a central heating radiator fitted with a control valve. Open loop control describes how the markings on the valve are used to control room temperature. For example, experience may have shown that 30 percent open provides a room temperature of 25º C. So this is where the valve is set to maintain that temperature. However, if it is a sunny rather than a cloudy day and the room heats up, there is no feedback mechanism to close the valve and maintain the temperature to take account of the change in circumstances. Closed loop control adds that feedback. By adding a room thermostat the temperature in the room would be monitored and a signal provided to close the radiator valve as the required temperature is reached thus maintaining the temperature at the set level.
A switchgear room is a room in a building which contains switchgear. It is typically a locked room in the ground floor of a building where the service enters the property. It would usually contain the supply authority's meters and the main protective devices (fuses, breakers) for the building's electrical installation. The room should not be used for storage or any other use.A different answerA switchgear room is an enclosed space - within an electrical power generating station or substation - in which are located high-voltage circuit breakers, protective relays, battery supplies, etc. The types of circuit breakers located inside switchgear rooms are indoor types and not suitable for locating in the substation compound. In the UK, these types of circuit breaker are typically metal-clad 11-kV oil circuit breakers (OCBs), and are supplied from primary (33/11-kV) transformers located in the substation compound and, themselves, supplied from outdoor-type 33-kV circuit breakers in the same compound.
by increasing the room air change, pressure remains constant
It can help it if there is room to add a third party colling system to your laptop
precision air conditioning system is one type AC system which supply moisture less colling air.Generally we use it for electronics equipment or server room area.
There is only one battery to find and it is at the foot of the bed, the other battery is in the red box.
In a battery room the environment is corrosive, and the acid from the battery may leak, hence wooden stands are preferred.
On an older Beetles the battery is under the rear seat. Kind of a pain to get the seat out. but you have lots of room to get at the battery. Usually on the passenger side.
The car battery is the white box behind the ladder by the sand paper
No, Battery is not the same as Domestic Battery. Battery is the unlawful touching or another person. Domestic Battery is the unlawful touching of a family member, spouce, boyfriend, girlfriend, room mates. Domestic means someone you're living with or related too.
System overshoot is the room temperature that is way over the set room temperature from residual heat from the exchanger into the room after it has shut off. System lag is when the temperature drops below the set point on the thermostat.
A phone battery can be put into the freezer when overheated. After allowing the phone battery to cool down, remove it from the freezer let it come to room temperature, and place the battery back in the phone. Yes it will work.
In my opinion there's room for improvement in battery technology .The best is yet to come. laser beams in my dreams.
A warm room. A cold room will weaken ur immune system (not good).
Clarification needed: if you are in the same room with others who are smoking it?
