A recirculating bath includes a reservoir for receiving a working liquid, a recirculating pump, and at least one thermal element. The recirculating pump and thermal element are located externally to the reservoir so that the reservoir has an unobstructed working space. The thermal element may be thermally coupled to the working liquid through an interior surface of the reservoir, or the working liquid may be circulated over the thermal element by the recirculating pump in a chamber external to the reservoir. The recirculating bath may also include a lid that provides access to the reservoir by pivoting on a latching hinge. When open, the lid may provide a working surface adjacent to the reservoir. The lid may also include a selector that unlatches the hinge so that the lid can be removed. The recirculating pump may be fluidically coupled to the reservoir via a manifold.

A semi-open high-temperature heat pump system including a compressor, a direct-contact condenser, a heat exchanger, an evaporator, a water purifier, a cold water pump, a hot water pump, a circulating water pump, and a vacuum pump. A discharge port of the compressor is connected to the direct-contact condenser, the direct-contact condenser is connected to the evaporator via the heat exchanger, and the evaporator is connected to a gas suction port of the compressor via a gas vent on its top. An outlet of the water purifier is separately connected to the compressor, the direct-contact condenser, and the evaporator via the cold water pump. An outlet at the bottom of the evaporator is connected to the direct-contact condenser via the circulating water pump. The vacuum pump is connected above the direct-contact condenser, and the hot water pump is connected below the direct-contact condenser.

The systems and methods described herein relate to heating ventilation and air conditioning (HVAC) systems and water heating systems in relation to a building and residential automation system. Some embodiments of the systems and methods described herein relate to HVAC systems and water systems in relation to an integration of building or residential automation systems. Specifically, the disclosure relates to maintaining a desirable water temperature for a desirable time period. By reducing unnecessary heating of water, the systems disclosed herein may result in fewer wasted resources and a lower utility bill. In one embodiment, a method for security and/or automation systems may be disclosed. The method may comprise monitoring a status of a water heater and monitoring an occupancy status of a residence. The status of the water heater may adjust, automatically, based at least in part on the monitoring.

A hot water supply device (10) is provided with: a first device (for example, a kitchen remote controller (13)) for performing control relating to hot water supply; a second device (for example, a water heater (11)) that is communicably connected to the first device and performs control relating to hot water supply; and a communication unit that is provided in the first device and can be connected to an external communication network. The first device divides data of control software of the second device acquired from an external device (for example, a server (50)) via the communication unit, into a plurality of parts, and transmits to the second device.

Disclosed herein are WIFI and could enabled temperature control systems. The temperature control systems are configured to receive user temperature settings and preferences, and control a water heater based on the user temperature settings and preferences. The temperature control systems include two or more sampling rates for enabling a higher efficiency of operation compared to conventional water heaters.

A water heater and a cover assembly for the water heater is provided. The water heater includes a mixing valve disposed in fluid communication with each of a hot water conduit and a cold water pipe, to regulate temperature of hot water received from the hot water conduit. The cold water pipe branches from a cold water conduit and extends along a longitudinal axis of the tank to connect with the mixing valve. The cover assembly is mounted on a tank of the water heater. The cover assembly includes a first cover to conceal the cold water pipe, and a second cover to conceal the mixing valve and the hot water conduit extending between the tank and the mixing valve. The second cover is removably coupled to the first cover via one or more coupling elements.

The present application provides a baking equipment applied in a display panel manufacturing process. In the present application, the first and second pipes are communicated with each other and evenly distributed inside the baking plate, so that the heating liquid injected from the head end of the first pipe heats the baking plate evenly during flowing through the first and second pipes, which improves the uniformity of the baking temperature of the TFT array substrate to be baked by the baking plate, thereby ensuring the stability of the baking process of the TFT array substrate.

The present disclosure discloses a water heater, and a scale detection system and method. The scale detection system comprises: a first temperature detector configured to acquire a first temperature of a heat exchange zone of a water heating device; a second temperature detector configured to acquire a second temperature indicating a water temperature in the water heating device; and a controller in communication with the first temperature detector and the second temperature detector, and configured to acquire a temperature difference between the first temperature and the second temperature based on the first temperature acquired by the first temperature detector and the second temperature acquired by the second temperature detector, and determine that a scale generation amount in the water heating device reaches a preset threshold when at least one of the following judgment conditions is met: the first temperature is not less than a preset temperature threshold; and the temperature difference is not less than a preset temperature difference threshold. The present disclosure can ensure that a user can be reliably and timely reminded to clean the scale under different working conditions.
