摘要:
A tank for waste water partially or fully buried in the ground or immersed in water includes a wall made of a high thermal conductivity material, which in turn has a pair of walls forming a cavity creating a circuit of a convective fluid for heat exchange with both the waste water contained inside the tank and with the ground and/or groundwater external to the tank.

A system is shown for providing domestic hot water for potable use. The energy source is a steam powered heat exchanger. Water is heated in a heat engine package including the heat exchanger, a temperature operated pump and a condensate control valve. The heat package works in conjunction with a water storage package including a water storage tank and an electronic controller which controls the operation of the pump and condensate control valve. The electronic controller is operated so that the control of steam supplied to the system and flow of water through the heat exchanger ensures that steam is only present in the heat exchanger when there is a predetermined high flow rate of water.

The present invention discloses a solar heating and cooling central air-conditioning with a heat recovery system. The system includes a solar heating subsystem for providing supplementary energy to a heat pump, a buffer water tank for storing and minimizing energy loss, a domestic water heater for recovering unused heat, and an air handler ventilation and exchanger subsystem. All parts of the system are connected by antifreeze circulation pipes. The present invention combines the solar technology with the heat pump technology, making it work in extreme cold climate. The system is high energy efficient, versatile, safe, reliable, intelligent and flexible in installation.
摘要:
A heat exchanger for a shower tray can be arranged in the bottom of the shower tray for the heat recovery from wastewater so as to heat fresh water. To this end, the heat exchanger has a planar cover plate as the drain surface over which the wastewater drains. The cover plate forms the bottom of the shower tray, over which a lid that can be removed without the use of tools is arranged as a tread plate. The heat exchanger preferably includes a distributor element, which is arranged for distributing the wastewater over the drain surface. The distributor element is preferably a retaining element, which retains the wastewater at an upper edge of the drain surface and forms an overflow along the upper edge.

The present invention relates to a wastewater heat recovery apparatus monitoring system including a heat recovery apparatus and a monitoring apparatus. The heat recovery apparatus comprises: a settling filter unit that receives wastewater and settles sediment contained in the wastewater along a settling processing container; a heat-exchanging unit that receives the wastewater from which the sediment has been removed while passing through the settling filter unit, and simultaneously receives cold clean water, to perform heat exchange between the wastewater and the cold clean water to convert the cold clean water into hot clean water; a filtering unit installed between the settling filter unit and the heat-exchanging unit, for performing a first stage filtering of fine foreign substances contained in the wastewater that passes through the settling filter unit and a second stage filtering of fine foreign substances contained in the wastewater that passes through the heat-exchanging unit; and a heat recovery sensing unit that receives an input valve sensed by a connected wastewater pressure sensor, receives cold clean water temperature information sensed by a cold clean water temperature sensor, receives hot clean water temperature information sensed by a hot wastewater temperature sensor, and receives temperature information of a first wastewater sensed by a first wastewater temperature sensor; and receives temperature information of a second wastewater from a second wastewater temperature sensor. The monitoring apparatus is connected to the heat recovery apparatus through an information communication network to control and monitor the operating state of the heat recovery apparatus, to receive the pressure value, cold clean water temperature information, hot clean water temperature information, temperature information of the first wastewater, and temperature information of the second wastewater received from the heat recovery sensing unit, and to display an operating screen, the operating state, an alarm screen, a temperature graph, and a pressure graph of the heat recovery apparatus.
