An automatic laundry washing machine that is suitable for use in living units having no area set aside for laundry facilities is achieved by replacing the heavy bulky parts of the currently popular automatic washing machine design with a light flexible bag. A large portion of the volume of any washing machine is the vessel for containing the laundry solution and articles to be washed. That vessel is a flexible bag made of modern durable material so as to be collapsible both while in use and for storage. The method of use includes the complete process of washing, rinsing, and extracting excess water in an automatic cycle analogous to standard automatic washing machines popular today. The vessel containing the items being laundered is a waterproof laundry bag with automatic washing apparatus attached. Items are automatically washed in that bag. The automatic process includes cycles of filling, washing, rinsing and extracting such that the clothes are ready for a drying process such as hanging out to dry or putting into a tumble dryer. The agitating of the washing and rinsing cycles is accomplished without the familiar bulky agitator thereby reducing the volume requirements and the traditional wear and tear on the garments. By eliminating the bulky agitator and the spin water extraction method, the heavy transmission is also eliminated. The water extraction cycle is done in a much less violent way than the conventional spin cycle by allowing atmospheric pressure to collapse the washing vessel and press the water from the articles as the water and air are pumped from the vessel in the draining portion of the cycle. The cleaning ability of the water is enhanced by built in ionic processing of the water thereby reducing the required amount of laundry detergent. The agitating in the non-electrically conductive vessel generates static electric charges in the process and ions thus produced further enhance the cleaning ability of the water. Cavitation produced in a multi-frequency washing action further enhances the washing ability of the water. The washing machine is light, compact and collapsible and is as portable as a piece of luggage. The set up procedure is simple and no assembly is required beyond attaching a quick connect fastener to a water faucet and plugging in a power cord. The washing machine is light and takes little storage space. It can be put in a small closet or on a shelf when not in use. The minimum capacity of the washing machine is a single garment. The normal capacity of the washing machine is comparable to that of a standard household washing machine.

A forced air cooling tower includes an upright casing, and elevated water distribution system disposed in an upper portion of the casing and one or more fans for drawing air through the tower. The tower also includes a catch basin for collecting the cooled air and a pump for circulating the cooled water through a condenser and back to the top of the tower and to the water distribution system. The cooling tower also includes a controller and a variable frequency device for regulating the flow of air through the tower. A first temperature sensor senses the temperature T1 of the hot process water delivered to the water distribution system and a second sensor senses the dry bulb temperature of the air leaving the tower Tdbt2. A third sensor senses the temperature of the cooled water leaving the tower. The controller such as a computer and variable frequency drive controls the speed of the fan to minimize the difference in T1 and Tdbt2. A submaster control prevents the fan speed from being further reduced when a predetermined T2 (temperature of the cooled water) is reached.

A water supply system, particularly for an aircraft such as a passenger aircraft, includes a disinfecting unit with an electrolysis cell connected in series with a water storage tank including a water distribution pipe system and a circulating pump. A bypass pipe with a valve permits connecting the electrolysis cell to the distribution system or bypassing the electrolysis cell. The electrolysis cell disinfects the water by anodic oxidation. A salt solution container may be connected to the electrolysis cell to enhance the anodic oxidation. The pump circulates the disinfected water through the tank and/or through the entire system, whereby the water supply is disinfected and the disinfected water in turn disinfects the entire system.

The object of the present invention is to provide a compact lightweight heat pump hot-water supply system. The hot-water supply system heats water through heat exchange between high-temperature refrigerant of a heat pump circuit and water of a water circulating circuit. The system is an instantaneous water heater unit for instantaneously heating, at a water heat exchanger, water supplied through a water supply pipe and supplying hot water to a using end unit. In this system, therefore, large-capacity hot-water storage tank in conventional systems is no longer needed. Sufficient heat of condensation to heat water can not be produced, because pressure conditions of the heat pump circuit is not stabilized just after the start of operation. Therefore, during a short period of rising time, hot water stored in a hot-water supply tank and water from the water heat exchanger are mixed and the mixture is supplied to keep the hot water at a preset temperature. It is, therefore, possible to downsize the hot-water supply tank.
