The utility model content

For solving the defective that existing air-conditioner dehumidification function can not independent temperature-constant operation; The utility model provides a kind of double layer evaporation device air-conditioner system; Through three reversal valves; Control indoor set inside and outside layer evaporimeter and outdoor condenser work condition state, realized the independent operating of air-conditioner each item function.

The branch art scheme that its art problem that solves the utility model is adopted is: inside and outside double-deck combining structure evaporimeter is set in air conditioner room unit; Setting can be controlled one two or two layout four interface unsteady flow reversal valves of the different work condition state of the inside and outside layer of double layer evaporation device; Two one or the three layout four interface unsteady flow reversal valves that controlled refrigeration condenser work condition state and refrigerant flow to are set in off-premises station; Constitute the brand-new double layer evaporation device air-conditioner system of the complete independent operating of each operating mode, when refrigeration, heating condition, the parallel connection of indoor set double layer evaporation device is identical operating mode operation; When removing wet cooling condition; The series connection of indoor set double layer evaporation device is the different operating modes operations of condenser for skin for evaporimeter, internal layer, and the condenser of off-premises station is shifted out only empty from big system, and form the mini system circulation: the indoor circulation air is flowed through outer evaporimeter earlier by cool-down dehumidification; The internal layer condenser of flowing through again is raised to normal temperature laboratory again and disengages, and reaches the constant temperature independent operating that air-conditioner removes wet cooling condition.

The beneficial effect of the utility model is: solved existing air-conditioner fully; Dehumidifying can only utilize the defective of refrigerating function cooling, intermitten operation; Realized the dehumidification function independent operating; Constant temperature, continuous advantage satisfy under the various climate conditions in each region, to dehumidifying or refrigeration, the different needs that heats.
