Claims16
A heating and dehumidifying assembly comprising:
- a housing;
- dehumidifying means in said housing for drying the room air entering said housing along a path and comprising:
- compressor means for compressing a gas, and
- condensing means along said path and including a first plurality of finned tubes traversed by the gas for transforming said gas received from said compressor means into a liquid phase upon releasing part of the heat,
- expansion valve means for retransforming the liquid phase into a gaseous phase of said gas,
- evaporating means along said path receiving the gas from the valve means and including a second plurality of finned tubes traversed by the gas for heating said gas to form a condensate, and
- reservoir means operatively connected with said evaporating means for collecting said condensate;
- a casing in said housing and along said path housing said condensing and evaporating means, said first and second plurality of finned tubes being spaced apart at a predetermined distance and being rigidly connected with one another to allow simultaneous expanding and welding of said tubes of first and second plurality in said casing;
- and
- heating means in said housing along said path for heating the air in said housing.
A heating and dehumidifying assembly comprising:
- a housing formed with front and rear sides;
- means forming a respective opening on each of said front and rear sides, said openings defining an air path therebetween;
- fan means for directing a flow of the room air to be dehumidified along said air path,
- a casing in said housing along said air path and formed with at least one aperture;
- dehumidifying means in said housing for drying the room air entering said housing and comprising:
- compressor means for compressing a gas,
- condensing means in said casing for cooling said gas received from said compressor means, the gas releasing part of the heat to warm the room air in said housing trough said aperture upon transforming into a liquid phase in said condensing means,
- expansion valve means for retransforming the liquid phase of said gas into the gaseous phase,
- evaporating means in said casing and receiving said gas from said valve means for heating said gas to form a condensate, and
- reservoir means operatively connected with said evaporating means for collecting said condensate, said condensing and evaporating means being spaced apart and being rigidly connected with one another in said casing, said aperture preventing heat transfer from said condensing means to said evaporating means;
- heating means along said path in said housing for heating said room air;
- and
- switching means for monitoring said fan means to controllably alternate direction of the flow of the room air along said air path for defrosting said evaporating means.
The assembly defined in clam 12 wherein said sensor means includes a floater provided with a rod and a sensor connected with said rod and signalling a full state of said tank.
The assembly defined in clam 5 wherein at least one of said openings is provided with filtering means for preventing deposit of dust on said expansion valve.
A heating and dehumidifying assembly comprising:
- a housing;
- fan means in said housing for directing a flow of the room air to be dehumidified along an air path in said housing;
- dehumidifying means in said housing for drying the room air and comprising:
- compressor means for compressing a gas,
- condensing means along said path and including a first plurality of finned tubes traversed by the gas for transforming said gas received from said compressor means into a liquid phase upon releasing part of the heat,
- expansion valve means for retransforming the liquid phase into a gaseous phase of said gas,
- evaporating means along said path receiving the gas from the valve means and including a second plurality of finned tubes traversed by the gas for heating said gas to form a condensate, and
- reservoir means operatively connected with said evaporating means for collecting said condensate;
- a casing in said housing and along said path housing said condensing and evaporating means, said first and second plurality of finned tubes being spaced apart and being rigidly connected with one another;
- heating means in said housing along said path for heating the air in said housing;
- and
- means for varying a rotation speed of said fan means, said rotation speed being varied according to which of said heating means or said dehumidifying means has been activated.
