| 20090145155 | Rotating Bernoulli Heat Pump - Heat engines move heat from a source to a sink. In a subset of heat engines, called heat pumps, the temperature of the source is below that of the sink. A subset of heat pumps, called working-fluid heat pumps, accomplishes the heat-pumping function by varying the temperature of a working fluid over a range that includes the temperatures of both the source and the sink. A subset of working fluid heat pumps, called Bernoulli heat pumps, accomplish this temperature variation of the working fluid by means of Bernoulli conversion of random molecular motion into directed motion (flow). This invention is a Bernoulli heat pump in which Bernoulli conversion is accomplished using a rotating disk, similar to those used in computers for data storage. Most working fluid heat pumps used for cooling and heating accomplish the temperature variation by compression of the working fluid. In contrast to compression, Bernoulli conversion consumes no energy. | 06-11-2009 |

The active heat pumping system is integrated with the fan assembly and is operable to actively cool or heat air as the air passes through the fan assembly. In some embodiments, the heat pump comprised in the active heat pumping system is a solid-state heat pump, a vapor compression heat pump, or a Stirling Cycle heat pump. | 12-10-2015 |
| 20150362222 | REFRIGERANT DISTRIBUTION DEVICE AND A HEAT PUMP APPARATUS USING THE SAME REFRIGERANT DISTRIBUTION DEVICE - A refrigerant distribution device is provided for distributing refrigerant to a plurality of heat transfer tubes that constitute a heat exchanger. The refrigerant distribution device includes a first distribution device dividing refrigerant into a plurality of portions, and a plurality of two-way branch pipes each dividing refrigerant divided by the first distribution device into two portions to flow into two of the plurality of heat transfer tubes. | 12-17-2015 |
| 20160018153 | Maximizing Defrost Mode in Electrified Vehicle Having Dual Evaporator and Dual Heater Core Climate Control System - A method according to an exemplary aspect of the present disclosure includes, among other things, controlling a climate control system of an electrified vehicle by shutting off refrigerant flow to a rear portion of a heat pump subsystem in response to a defrost request. | 01-21-2016 |
| 20160061494 | Refrigerant Side Economizer - This invention provides a Refrigerant Side Economizer cycle and a fuel-heat based heating cycle for air conditioners, heat pumps, and chillers. The built-in refrigerant side economizer cycle can be substituted for an air-side economizer cycle or a water-side economizer cycle. It can provide an economizer cycle for split system air conditioners, chillers, coolers, and heat pumps. Also, it makes possible an economizer mode for variable refrigerant flow units. With this invention, the units can distribute heating from a fuel-heat source without compressor operation. During refrigerant side economizer mode, the refrigerant pump in the units maintains circulation without compressor operation, with a fraction of energy consumption. To allow for longer distance between split-system units, the refrigerant pump if needed can operate during compressor operation. | 03-03-2016 |
| 20160075213 | VEHICLE HEAT MANAGEMENT DEVICE - A vehicle heat management device applied to a refrigeration cycle includes a pump that suctions and discharges a heat medium, a heat medium cooler that exchanges heat between the heat medium discharged by the pump and low-pressure side refrigerant in the refrigeration cycle to evaporate the low-pressure side refrigerant and to cool the heat medium, a heat medium circulation device through which the heat medium whose heat is exchanged in the heat medium cooler flows and in which the heat medium absorbs heat by its sensible heat change, and a heat medium flow control part that increases a flow rate of the heat medium flowing through the heat medium circulation device when an amount of the heat absorbed by the heat medium in the heat medium circulation device is determined to be larger than a predetermined amount of heat. | 03-17-2016 |
| 20160091233 | VAPOR COMPRESSION AIR-CONDITIONING SYSTEM EQUIPPED WITH ENERGY EFFICIENCY BOOSTER - A vapor compression air-conditioning system equipped with an energy efficiency booster ( | 03-31-2016 |
| 20160109155 | HEAT PUMP WATER HEATER APPLIANCE - The present subject matter provides a heat pump water heater appliance with a mounting assembly for coupling a compressor to a plate within a casing of the heat pump water heater appliance. The mounting assembly includes a post that extends through a foot of the compressor and a fastener that extends through the bracket and the plate into the post in order to secure the bracket and the post together. An attachment mechanism secures the post and the foot of the compressor together. | 04-21-2016 |
