    摘要： The disclosed technology includes devices and methods for optimizing refrigerant flow in a heat exchanger. The disclosed technology can include a heat exchanger unit that has a first heat exchanger coil that experiences a first airflow of air passing over the first heat exchanger coil and a second heat exchanger coil that experiences a second airflow of air passing over the second heat exchanger coil. The first airflow can be less than the second air flow. The disclosed technology can include distributor tubes in fluid communication with the heat exchanger coils to direct a flow of refrigerant from an expansion valve to the heat exchanger coils. The first distributor tube can reduce a flow rate of refrigerant to the first heat exchanger coil such that a greater amount of refrigerant is directed to the second heat exchanger coil and refrigerant exits each heat exchanger coil as a superheated vapor.

    摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a heating fluid circuit, a cooling fluid circuit, and a storage fluid circuit. A thermal system of the HVACR system absorbs energy from the storage fluid circuit and rejects it to the heating fluid circuit. The storage fluid circuit includes thermal storage tanks containing thermal storage material that can provide energy for heating or absorb energy for cooling depending on the state of the thermal storage material. Heating can be provided using the heating fluid circuit and the heat provided by the thermal system. Cooling can be provided using the cooling fluid circuit by absorbing energy from the conditioned space using a cooling fluid and rejecting energy from the cooling fluid to the storage fluid circuit including the thermal storage tanks. The thermal storage tanks can also have heat added to them using an air source heat pump system to provide sufficient storage for heating operations.

    摘要： An apparatus and method for increasing efficiency of heating/cooling systems in buildings and other facilities. An elongate pipe filled with water or other fluid medium forms a thermal gradient header having temperature zones that are progressively warmer towards one end and cooler towards the other. The heating/cooling systems are connected to the header so as to draw circulating fluid from zones that are closest in temperature to the optimal intake temperature of each system, and to discharge fluid back to the header at zones that are closest to the temperature to the optimal output temperature of each system. The heating/cooling systems may be, for example, air conditioning systems, water heating systems, ice making systems, and so on; the facility may be a single building or comprise multiple buildings. The pipe forming the thermal gradient header may be routed back and forth in the facility to define a series of legs at different temperatures, with the intake and output lines of each system being connected to that leg having the temperature closest to optimum. Additional lines and control valves may enable the systems to draw from/discharge to different legs under different operating conditions, such as at different seasons. The system maximizes efficiency by allowing each system to take advantage of the thermal output of other systems. A boiler or other source of makeup heat may be connected to the thermal gradient header if necessary, and any excess heat may be supplied from the header a thermal ground field for later use or may be rejected as necessary.

    摘要： A thermal storage agent used, for example, for air-conditioning systems of buildings, exhibiting excellent thermal storage, thermal conduction and safety, and a manufacturing method thereof. The thermal storage agent contains particulate oil gel bodies prepared by letting an oil absorbent resin absorb, and thus swell with, a thermal storage oil-soluble substance, wherein the oily gel bodies have a unitary volume of not less than 0.01 cm.sup.3 and are in contact with one another. A manufacturing method in accordance with the present invention can produce the thermal storage agent by letting an oil absorbent resin that is prepared by suspension polymerization in a solution containing the oil-soluble substance absorb, and thus swell with, the oil-soluble substance.

    摘要： A method and apparatus for improved latent heat extraction combines a run-around coil system with a condenser heat recovery system to enhance the moisture removing capability of a conventional vapor compression air conditioning unit. The run-around coil system exchanges energy between the return and supply air flows of the air conditioning unit. Energy recovered in the condenser heat recovery system is selectively combined with the run-around system energy extracted from the return air flow to reheat the supply air stream for downstream humidity control. A control system regulates the relative proportions of the extracted return air flow energy and recovered heat energy delivered to the reheat coil for efficient control over moisture in the supply air flow. Auxiliary energy in the form of electric heat energy is further added to the recovered heat energy for additional reheat use.
