Abstract
A temperature and humidity adjusting apparatus has an air cooling and dehumidifying device, an air heater and a humidifier arranged in order. The air cooling and dehumidifying device includes thermoelements that use the Peltier effect. The humidifier includes hollow yarn bodies, each of which are formed by winding metal wire that serves as a heater on the outer periphery of a hollow yarn that is formed into hollow construction from heat resistant fiber. The humidifier also includes means for supplying water to each of the hollow yarn bodies and a power supply that supplies power to the metal wire.
Claims5
A temperature and humidity adjusting apparatus comprising an air cooling and dehumidifying device, an air heater, and a humidifier, wherein:
- said air cooling and dehumidifying device includes thermoelements that utilize the Peltier effect;
- and
- said humidifier includes:
- a plurality of hollow yarn bodies, each said yarn body including a hollow yarn formed from fiber and metal wire that heats when supplied with electrical power, each said yarn body being formed by winding metal wire on an outer periphery of the hollow yarn;
- means for supplying water to each of said hollow yarn bodies;
- and
- power supply means for supplying electrical power to said metal wire.
A method for controlling a temperature and humidity adjusting apparatus that includes an air cooling and dehumidifying device, an air heater, and a humidifier, the air cooling and dehumidifying device including thermoelements that use the Peltier effect, and the humidifier including:
- a plurality of hollow yarn bodies, each of which includes a hollow yarn formed from fiber and metal wire that heats when supplied with electrical power, and each of which is formed by winding the metal wire on the outer periphery of the hollow yarn,
- means for supplying water to each of the hollow yarn bodies, and
- power supply means for supplying electrical power to the metal wire,
- the method for controlling the temperature and humidity adjusting apparatus comprising the steps of:
- measuring a temperature and a relative humidity at an outlet of said temperature and humidity adjusting apparatus,
- calculating an absolute humidity corresponding to said relative humidity,
- deriving a temperature error amount between the measured temperature at the outlet of the apparatus and a set temperature,
- operating one of the air heater and the air cooling and dehumidifying device based upon the temperature error amount,
- deriving a humidity error amount between the absolute humidity at the outlet of the apparatus and a preliminarily derived set absolute temperature, and
- operating one of the humidifier and the air cooling and dehumidifying device based upon the humidity error amount.
