Abstract

A dual mode water leak detector is combined with a HIVAR air condition system or unit. The air conditioning unit or system uses chilled water for cooling or hot water or electric coils for heating and employs means for supplying heated or cooled air into a floor void and channeling return air to designated vents under the floor or through a false ceiling. In addition a water sensor includes an enclosed housing having a bottom or base and four electrical contacts extending through the base and positioned above the floor by about 2 mm by four rubber spacers or feet. In addition a first circuit connects a first and a second contact separated from one another by an airspace to a pair of banana clips for turning the HIVAR system off when water between the first and second contacts is completed due to the presence of water. A second circuit includes a switch and a 60K OHM resistor connecting that circuit to a first of the contacts and second of the contacts when the switch is in a closed position.

Claims

1. A dual mode water leak detector in combination with a HIVAR air conditioning system, said combination comprising:

a HIVAR air conditioning unit that uses chilled water for cooling and hot water or electric coils for heating and means for supplying heated or cooled air into a floor void and channeling return air through designated vents under the floor or through a false ceiling;

a water sensor including an enclosed housing having a bottom or base and four electrical contacts extending through said base, and four insulated spacers or feet on the bottom or base of said housing for spacing said contacts at about 2 mm above a floor or bottom of a cabinet;

a first circuit including a pair of banana clips, said first conduit connecting a first and a second contact separated from one another by an airspace to said banana clips for turning said HIVAR system off when water between said first and second contacts completes a circuit with to the HIVAR unit;

a second circuit, and means for turning the HIVAR system off, a switch and a 60K OHM resistor connected in said second circuit to said first of said contacts and said second of said contacts when said switch is in a closed position to complete said second circuit by connecting said first and second contacts through said 60K OHM resistor through said banana clips to said means for turning said HIVAR system off;

wherein said 60K OHM resistor is removed from said circuit when said switch is in an open position, and

wherein said enclosed housing includes a removable top which includes said switch and a pair of banana connectors.

2. A dual mode water leak detector in combination with a HIVAR air conditioning system according to claim 1 and in which said insulated spacers are made of rubber.

3. A dual mode water leak detector in combination with a HIVAR air conditioning system according to claim 1 in which said insulated spacers are made of neoprene.

4. A dual mode water leak detector in combination with a HIVAR air conditioning system according to claim 3 which includes a variable speed control to vary the volume of air flow to match the environmental requirements.

5. A dual mode water leak detector in combination with a HIVAR air conditioning system, said combination consisting of:

a HIVAR air conditioning unit that uses chilled water for cooling and hot water or electric coils for heating and means for supplying heated or cooled air into a floor void and channeling return air through designated vents under the floor or through a false ceiling;

a water sensor including an enclosed housing having a bottom or base and four electrical contacts extending through said base, and four insulated spacers or feet of rubber on the bottom or base of said housing for spacing said contacts at about 2 mm above a floor or bottom of a cabinet;

a first circuit including a pair of banana clips, said first circuit connecting a first and a second contact separated from one another by an airspace to said banana clips for turning said HIVAR system off when water between said first and second contacts completes a circuit with to turn said HIVAR unit;

a second circuit including means for turning the HIVAR system off, a switch and a 60K OHM resistor connected in said second circuit to said first of said contacts and said second of said contacts when said switch is in a closed position to complete said second circuit by connecting said first and second contacts through said 60K OHM resistor through said banana clips to said means for turning said HIVAR system off;

wherein said 60K OHM resistor is removed from said circuit when said switch is in an open position and in which said insulated spacers are made of rubber and in which said enclosed housing includes a removable top and in which the HIVAR unit includes a variable speed control to vary the volume of air flowing to match the environmental requirements and a sound attenuator and filter for reducing the noise of said system and providing clean air.
