Abstract
An air temperature and humidity control device using a liquid-desiccant humidity controller thermally coupled to a heat pump is disclosed. The humidity controller may include a contactor having at least one contact module with a porous sidewall that is permeable to water vapor and impermeable to the liquid desiccant. The disclosed device provides air temperature control through heat transfer between the liquid desiccant and heat pump and provides humidity controls through water transfer between the desiccant and surrounding air.
Claims20
An air temperature and humidity control device comprising:
- a heat pump comprising a condenser, an evaporator, and a compressor;
- a humidity controller comprising a first contactor fluidly coupled to the condenser and evaporator, the first contactor comprising at least one contact module including aporous sidewall defining an internal space for carrying a liquid desiccant therein;
- a blower for generating an airflow in communication with the sidewall of the contact module.
A method of controlling air humidity and temperature, the method comprising:
- circulating a refrigerant in a heat pump comprising a condenser and an evaporator;
- circulating a desiccant in a humidity controller comprising a contactor fluidly coupled to the condenser and evaporator, the contactor comprising at least one contact module including a porous sidewall defining an internal space in which the liquid desiccant flows;
- and
- generating airflow in communication with the sidewall of the contact module.
