Abstract: A water heating system including a housing, a water tank and a valve assembly is disclosed. The housing may include a cover, which includes a cover top surface and a cover bottom surface. The water tank may be disposed in a housing interior portion under the cover bottom surface. Further, the valve assembly may include a valve, a mixer, and a shunt. The valve may be connected with the mixer via the shunt. Furthermore, the valve may be configured to receive a supply of cold water and control a flow of cold water to the water tank and the mixer based on an operating state of the valve. The shunt may be disposed under the cover bottom surface and above the water tank.

Abstract: A water heating system is disclosed. The water heating system may include a valve assembly configured to receive cold water and hot water, blend the cold water and the hot water, and output a blended water at a desired water temperature based on a valve component position. The water heating system may further include a position sensor configured to monitor a valve component position. The water heating system may further include a controller configured to cause movement of a valve component to a desired valve component position. The controller may verify that the valve component position is equivalent to the desired valve component position based on inputs obtained from the position sensor and perform a predetermined action when the valve component position is different from the desired valve component position.

Abstract: A water heating system including an inlet, a water tank, a mixer and a valve is disclosed. The inlet may be configured to receive a supply of cold water, and the water tank may be configured to store hot water. The mixer may be configured to receive hot water from the water tank. The valve may be attached to the inlet and be in fluid communication with the water tank and the mixer. The valve may be configured to receive the cold water from the inlet and control a flow of cold water into the water tank and the mixer based on an operating state of the valve.

Abstract: A valve including an inlet port, a valve stack and an actuator assembly is disclosed. The inlet port receives a supply of cold water, and the valve stack receives the cold water from the inlet port. The valve stack includes a first disc and a second disc in contact with each other. The first disc is configured to axially rotate relative to the second disc. The valve stack further includes a shaft connected to the first disc. The actuator assembly includes an actuator connected to the first disc via the shaft. The actuator is configured to cause an axial rotation of the first disc relative to the second disc. The valve stack is configured to control a flow of cold water to first and second external components based on a position of the first disc relative to the second disc when the first disc is axially rotated.

Abstract: Described herein is a refrigerant loop heat sink. The heat sink may be provided in contact with refrigerant tubing that is connected to an existing refrigerant loop of the heating and/or cooling appliance. The heat sink may then be provided in thermal contact with electronic components (or a printed circuit board (PCB) to which the electronic components are mounted) of the heating and/or cooling appliance). In this manner, any heat that is produced as a byproduct of the operation of the electronic components may be transferred from the electronic components into the heat sink and the refrigerant tubing. The heat may then be transferred to the refrigerant that is flowing through the refrigerant tubing to cool the electronic components. This provides an alternative to an air cooled system by which heat from the electronic components is dissipated by blowing cooler air from a fan within the heating and/or cooling appliance over the electronic components.
