The present invention relates generally to cooling and heating apparatus, and more specifically, to a multi-purpose cooling and heating apparatus for chilling and heating of liquids.

There are numerous events and activities where one desires to enjoy cool beverages. However, many such events and activities are located in places where there is no access to cool beverages chilled by traditionally means such as refrigerators. In particular, remote locations such as on the golf courses, sporting events, outdoor concerts and other outdoor activities, do not facilitate the easy distribution of cool beverages. Easy distribution of cool beverages is also desirable at resorts, bars and restaurants. Most consumers at these activities desire cool beverages. Numerous means have been developed to provide such beverages. Beverage coolers or chillers are widely used in such places households, commercial places such as bars, restaurants and offices. Such chillers commonly consist of a receptacle for a beverage and refrigerating means, which is operated by electricity or natural gas. The coolers are generally quite heavy because of the weight of the refrigerating means and the beverage receptacle and for that reason are not portable. They are also, of course, not suitable for use where there is not a source of power such as outdoors. Certain beverages are highly sensitive to temperature, which can affect their appeal, both in taste and appearance. Beer, for example, is most flavorful and visually appealing when drunk in a narrow temperature range of from about I ⁴ to 5° C. When beer is dispensed or poured directly from a refrigerated container, maintenance of the ideal drinking temperature presents no real problems.

The most typical manner to provide cool beverages at remote locations is to transport canned beverages in coolers containing ice and distribute the canned beverages at the remote location. If the contents are not consumed, the content may go stale. Also, there's a chance of contamination because of handling by bare hands. Also, the cans or bottles are kept in an ice box, in which the ice melts quickly due to regular opening of the lids io retrieve the bottles or cans, and thereby requiring more ice to cool cans or buttles. Further, the use of individual cans or bottles reduces the volume of beverage one is able to transport to such remote locations since the can packaging occupies the limited cooler space.

U.S. Pat. No. 4,225,039 describes a portable beverage cooler and dispenser. The apparatus includes an air cylinder for pressurizing beer kegs. The beer kegs are located in a housing. The beer kegs are connected to a coiled dispensing hose also located in the housing. The hose passes through ice located in ice chambers. This serves to cool the beer before it is dispensed through spigots at the top of the apparatus. In addition, U.S. Pat. No. 2,223,152 describes a stationary beer cooling device. The device is not pressurized. The device cools the beer by circulating it through a cooling coil which is immersed in an ice water bath. The cooling coil is protected by a perforated metal sleeve so as to permit an operator to agitate the ice bath with a stick or a rod.

The patent application US 20070084233 Al. entitled "Beverage cooler" discloses a beverage cooler that includes a vessel for a coolant such as ice water or a conventional coolant such as glycol or Freon. A coil is mounted in the interior of the vessel. The coil is made up of a number of vertically spaced joined circles, which are spaced apart from each other and from the interior wall of the vessel. The coil has an inlet through which a beverage from an external source, separate and apart from the cooler, enters the coil. A drain located above the coil carries off excess coolant. A tap at the outlet of the coil controls the flow of the beverage from the coil. However, the cooler cannot be used for heating and other purposes.

US patent application US 6502415 B2 further discloses an apparatus is provided for cooling a carbonated beverage stored in a container and dispensing non-foamed carbonated beverage. A method of cooling and delivering non- foamed beverage with the apparatus is also provided. The beverage is preferably beer. The apparatus comprises a housing that has a number of chambers. A chamber can optionally be provided for receiving a number of beer kegs. A pressurizing device is attached to a beer keg for maintaining the beer under pressure in the keg. A conduit is received in one of the chambers and communicates between the beer keg and a tap located on the exterior of the apparatus. A water and ice cooling mixture is circulated over the conduit in the same chamber for cooling the conduit A perforated vessel surrounds the conduit to protect the conduit and the agitators from being damaged by ice particles. At least two agitators for circulating the cooling fluid over the conduit are located in chamber where the conduit is received. The agitators are positioned to continuously circulate cold water over the conduit for maximum heat exchange.

Hence there exists a need for an instant heater or cooler apparatus that is self- sufficient so that it can be used where there is no source of power. The needed apparatus would be compact, scalable, easy to maintain and operate, can be used for heating and cooling without structural modiiications. etc.
