Documents received on: C" 0 2 2 FEB 1999 3 (DBah Batch No: Q:AOPERWKAT\HUANG.053 22/2/99 -la- HEATING AND COOLING DEVICE The invention relates to a heating and cooling device.

Typically, a steaming room and a water massage pool are provided in addition to a swimming pool. A heating apparatus is provided for supplying the heated water and/or the vaporized air to the water massage pool and/or the steaming room. The heating apparatus may not be used as an air conditioner. In addition, after the water heated by the heating apparatus reaches a predetermined high temperature, the heating apparatus should be shut off for safety purposes and may not be operated continuously to supply the heated water.

The invention is to provide a heating and cooling device which may be operated continuously and may be used as an air conditioner.

FIG. 1 is a schematic view of a heating and cooling device; and FIG. 2 is a partial schematic view illustrating the air conditioner of the heating and cooling device.

Referring to the drawings, a heating and cooling Udevice cuiomprises a microprocessor or a central processor unit (CPU) 21 which is energized by a power supply 20 and which is coupled to a compressor 23 via a pressure regulator 22. The compressor 23 is engaged in a pipe 28 for treating the heating or cooling media received in the pipe 28 to a high temperature and to a 2 high pressure, and for circulating the heating or cooling media. A condenser 30 includes two heat exchangers 31, 32 engaged in the pipe 28 for receiving the heated media from the compressor 23, and coupled to a container 33 and a tank 35 respectively via two pumps 34, 36. The pumps 34, 36 may circulate the water in the container 33 and in the tank 35 through the heat exchangers 31, 32 for heating the water. The container 33 is insulated for preserving the heat of the heated water. The heat of the heated water received in the tank 35 may be exchanged with the air in the environment.

An evaporator 50 includes a heat exchanger 51 engaged in the pipe 28 and a vessel 52 coupled to the heat exchanger 51 via a pump 53 which may pump the water in the vessel 52 through the heat exchanger 51.

An expansion valve 40 is engaged in the pipe 28 and disposed between the heat exchangers 51, 32. The heat of the media flowing through the heat exchangers 31, 32 may be transmitted to the water in the container 33 and in the tank 35 such that the temperature of the media may be decreased. The expansion valve 40 may decrease the pressure of the media. The media then may flow through the heat exchanger 51 for receiving the heat from the water in the vessel 52 and for cooling the water in the vessel 52. A number of sensors 80, 81, 82, 83 are coupled to the CPU 21 and are disposed between 3 the compressor 23, the condenser 30, the expansion valve 40 and the evaporator 50 for sensing and sending the temperatures to the CPU 21. The container 33 includes an outlet 332 for supplying the heated water to either or all of the swimming pool 10, the steaming room 11, the water massage pool 12, and/or the shower room 13, and includes an inlet 331 for receiving fresh water or for recycling the water from the pools 10, 12 and the rooms 11, 13. The vessel 52 includes an inlet 521 for receiving water from a water reservoir and an outlet 522 for supplying the cooled water out from the vessel 52.

One or more hoses 70 couple the tank 35 to the vessel 52 and one or more pumps 71 may pump the water between the tank 35 and the vessel 52 for decreasing the water temperature in the tank 35 and/or for increasing the water temperature in the vessel 52 when required. One or more tubes 60 further couple the container 33 to the vessel 52 and one or more pumps 61 may pump the water between the container 33 and the vessel 52 for decreasing the water temperature in the container 33 when the temperature of the container 33 is too high and/or for increasing the water temperature in the vessel 52 when the temperature of the vessel 52 is too low. The device may thus be continuously operated when the temperature of the vessel 52 is too low or when the temperature of the container 33 is too 4 high. One or more conduits 62 couple the container 33 to a housing 6 by a pump 64, and one or more ducts 66 couple the vessel 52 to the housing 6 by a pump 68.

As shown in FIG. 2, the conduits 62 and the ducts 66 each includes a portion extended inward of the housing 6 so as to be blown by a fan device 65 and so as to form an air conditioner. When the heated water is pumped through the conduits 62 and when the fan device is energized to blow the air outward through the outlet 63, an air heater may be formed. When the cooled water is pumped through the ducts 66 and when the fan device 65 is energized to blow the air outward through the outlet 63, a cooling air may be supplied. When the heated water and the cooled water are supplied through the conduits 62 and the ducts 66, the duct 66 may be used as a condenser for condensing the water from the air and for collecting the condensed water .wilh a collector 69. The dried air may then be heated when the air is blown through the conduits 62. An air conditioner may thus be formed. The pumps 34, 36, 53, 61, 64, 68, 71 are coupled to the CPU 21 so as to be controlled and operated through the CPU 2i.

In operation, the pumps 71 may pump the heated water from the tank 35 to the vessel 52 in order to increase .the water temperature in the vessel 52 when the temperature in the vessel 52 is just below the predetermined value. When the water temperature in the 5 vessel 52 is too low, the pumps 61 may pump the heated water from the container 33 to the vessel 52 for quickly decreasing the water temperature. The power to the compressor 23 may-be decreased if the water temperature in the vessel 52 may not be increased by the heated water from the container 33. The cooled water in the vessel 52 may be supplied to the container 33 or the tank 35 for decreasing the water temperature in the container 33 or the tank 35. The power to the compressor 23 may be decreased for preventing the water to be over heated and for allowing the device to be continuously operated.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations suchas "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
