Water cooler cum air conditioner

AIM

To design a water cooler having a container with a reservoir for storing

water has a thermoelectric module operable to cool a conductor plate and form

ice in the reservoir. A temperature sensor connected to the plate senses the

temperature of the plate and activates a timer when the temperature is below

the temperature at which water freezes. The timer operates a selected period of

time to allow a block of ice to be formed on the plate. A photoelectric sensor

operable to sense a selected size of the block of ice functions to actuate a

switching device that changes the polarity of the electric power supplied to the

thermoelectric module to supply heat energy to the plate to release the block of

ice from the plate. The released block of ice floats in the water in the reservoir

and cools the water and provides an improved air-conditioner. Basically, the air-

conditioner comprises casing means mountable within an opening into a room,

air-conditioning means contained within the casing, and blower means contained

within the casing for drawing air from the room into the casing and proximate to

the air-conditioning means for conditioning thereby and then discharging the

conditioned air to the room. However, in particular accordance with the present

invention, the blower means that is contained within the air-conditioner has an

impeller rotatable journalled between two spaced apart blower housing walls and

is provided with scroll means that can perform a dual function of bridging the two

housing walls and also providing a plurality of air discharge ports from the blower

housing.

APPLICATION

Hospital operating theatres, in which air is filtered to high levels to reduce infection risk and

the humidity controlled to limit patient dehydration. Although temperatures are often in the

comfort range, some specialist procedures such as open heart surgery require low

temperatures (about 18 °C, 64 °F) and others such as neonatal relatively high temperatures

(about 28 °C, 82 °F).

COMPRESSOR

RADIATOR

RADIATOR MOTOR FAN

WATER TANK

Cleanrooms for the production of integrated circuits, pharmaceuticals, and the like, in which

very high levels of air cleanliness and control of temperature and humidity are required for

the success of the process.

Facilities for breeding laboratory animals. Since many animals normally only reproduce in

spring, holding them in rooms at which conditions mirror spring all year can cause them to

reproduce year-round.
