This invention is related to a heater-humidifier-dehumidifier unit, and more particularly to a heater-humidifier-dehumidifier unit which is mounted in respective compartments of a housing.
A lot of air conditioning apparatuses have been developed for providing proper living and working conditions in a defined area in proportion to the size of the particular apparatus. For example, a heater, a cooler, a humidifier and dehumidifier constitute known air conditioning apparatuses. These air conditioning apparatuses are separately manufactured, and each apparatus is chosen to provide a desirable condition in an area to be air-conditioned.
Therefore, air conditioning apparatuses must be bought individually according to the need desired, that is, when warming of the area is desired, a heater is required. When removing moisture from humid air, a dehumidifier is required. When providing proper humidity in dry air, a humidifier is required. Thus, this causes an increase of installment costs, and an increase of dead space due to the occupation of a space by an unused air conditioning apparatus.
Further, the comfort of the space to be air-conditioned deteriorates in proportion to the operation of the air conditioning apparatus. That is, when in the warming operation, air becomes less humid or drier and when in a cooling operation, the air becomes more humid. Hence, a combination unit is required to compensate for the above problems.
