A typical "portable" dehumidifier can be moved about on built-in casters. A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air. [1] This is done usually for health or thermal comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It ...
HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...
The differential pressure trip is connected to the inlet and the outlet of the main filter of the air blower. Failure is indicated by a decrease in the differential pressure. The low-pressure trip connects to the main filter outlet. If the pressure drops below a pre-set level, the trip relay operates.
More than 1.5 million dehumidifiers are under recall following reports of nearly two dozen fires, according to the U.S. Consumer Product Safety Commission. According to the CPSC, the now-recalled ...
Human water losses, both respiratory, and insensible water loss like sweat, range in average 0.75 L/d in sedentary adults. [14] However, most people do not spend most of the day at home. Houseplants may also be used as natural humidifiers, especially if they are placed in fabric flowerpots , since they evaporate water into the air through ...
The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to produce a relative humidity of 100%. [1] This temperature depends on the pressure and water content of the air.
The frequency of nosocomial infections in British hospitals prompted the National Health Service (NHS) to research the effectiveness of anions for air purification, finding that repeated airborne acinetobacter infections in a ward were eliminated after the installation of a negative air ioniser — a promising result, although more evidence is ...
A thermostat is a system that monitors and regulates a heating or cooling system. It can be used to set the desired temperature at which it keeps the environment either heated or cooled. two-stage (cooling and heating) A two-stage air conditioner is designed to operate on high and low settings during different weather conditions and seasons.
