Abstract

The present disclosure is directed to a mechanical and powerless leak detection and shutoff system that may be used in any commercially available water heater, e.g., both gas and electric. The system includes a spring-loaded shutoff assembly having a valve member operatively coupled to a fluid inlet line of the water heater. A handle of the shutoff assembly is maintained in an open configuration via a latching mechanism until a force is applied to cause the latching mechanism to release the handle and actuate the valve member to shutoff fluid flow through the fluid inlet line. The shutoff assembly is operatively coupled to a leak detection assembly via a cable. The leak detection assembly uses a fluid-soluble material that dissolves when exposed to fluid to thereby pull the cable to apply the force to disengage the latching mechanism.

Heat Pump With Drainage for Low Ambient Temperature Conditions

Abstract

Heat pumps are often desired to be used over other types of HVAC units given their efficiency. In some cases, this efficiency may be further improved by using condensate that is naturally produced by an indoor coil of the heat pump when in a cooling mode. For example, any accumulate condensate may be “thrown” onto any components of the heat pump using a “slinger ring” attached to a fan inside the unit. However, this condensate accumulation may be problematic in a heating mode of the heat pump because the water may freeze and prevent the fan and/or corresponding motor from properly functioning. Thus, the systems and methods provided herein present a heat pump including a multi-layered basepan including an outdoor coil tray that allows condensate to be routed to the drain platform underneath the unit while limiting the ability of condensate to reach the slinger ring in the heating mode.

Abstract

Disclosed are systems and methods for automated furnace inducer sensor output verification. A furnace may include a sensor, such as a transducer, that may be used to measure pressure within the furnace (for example, pressure resulting from the operation of a draft inducer blower and/or any other component of the furnace). It is possible that the data produced by the sensor may remain relatively fixed for a given period of time. However, this makes it difficult to determine if the data is valid or if the sensor is malfunctioning. Given this, an algorithm is used to change a motor speed of the inducer blower. The subsequent data that is produced by the sensor is then monitored to determine if an expected change in the data occurs. If the change does not occur, then it may be determined that the sensor is malfunctioning.

Abstract

Systems, methods, and apparatuses for heating water are provided herein. A water heating system is disclosed, which includes a burner, a vapor-compression cycle system, and a water line in communication with the burner and the vapor-compression cycle system. The water heating system may be a tankless, or on demand, water heating system. Water within the water line may be initially heated by the vapor-compression cycle system before the water enters the burner. In this manner, the water may be preheated using the vapor-compression cycle system before the water is further heated by the burner.

The disclosed technology includes a heat pump having a thermal energy storage (TES) material. The heat pump can include a first heat exchanger to exchange heat between ambient air and refrigerant, a second heat exchanger to exchange heat between the refrigerant and air supplied to a climate-controlled space, and a third heat exchanger to exchange heat between the TES material and the refrigerant in a first fluid path and the refrigerant in a second fluid path. The heat pump can include a first compressor to circulate refrigerant to the first, second, and third heat exchangers and a second compressor to circulate refrigerant to the second and third heat exchangers. The first compressor can facilitate heat exchange between the ambient air and the TES material and the second compressor can facilitate heat exchange between the TES material and the air supplied to the climate-controlled space.

Abstract

A mixing valve assembly is disclosed. The mixing valve assembly can include a cold water connector, a hot water connector, an electronic valve system, and a tube. The cold water connector can have a through-hole configured to slideably receive at least a portion of a first tubular portion of a cold water inlet, and the hot water connector can have a through-hole configured to slideably receive at least a portion of a second tubular portion of a hot water outlet. The electronic valve system can be configured to transition a valve between an open configuration and a closed configuration such that cold water can be selectively permitted to flow from the cold water connector to the hot water connector. The mixing valve assembly can be configured to selectively permit cold water to bypass the tank of water heater.

Abstract

The disclosed technology includes systems and methods for a heat pump water heater. The disclosed technology can include a heat pump water heater system having an evaporator, a condenser, a vapor injection line, a compressor, and a multi-fluid heat exchanger. The vapor injection line can include an expansion valve to transition refrigerant received from the condenser at a first pressure to a second pressure. The compressor can be configured to circulate refrigerant through the condenser, the multi-fluid heat exchanger, the vapor injection line, and the evaporator. The multi-fluid heat exchanger can be configured to receive refrigerant at a first pressure from the condenser, refrigerant at a second pressure from the vapor injection line, and water. The multi-fluid heat exchanger can further facilitate heat transfer between the refrigerants at the first and second pressures and the water to preheat the water before the water is passed through the condenser.
