A condensate management system is adapted for use in a personal comfort system with an air conditioning system having a thermoelectric engine including a thermoelectric core, a supply heat exchanger and an exhaust heat exchanger. Condensate is managed by a primary condensate management system configured to draw condensate away from the thermoelectric core, the supply heat exchanger and/or the exhaust heat exchanger using wicking material. Optionally, a secondary condensation management system may be included which is configured to generate a condensate air flow operable for drawing moisture away from a collection tray.

Split solid adsorption cooling system

Номер: US20120006049A1
Автор: Chao-Yu Chen, Chi-Bin Wu, Ting-Kuan Li, Yu-Ming Sun
Принадлежит: Chung Hsin Electric and Machinery Manufacturing Corp

A split solid adsorption cooling system is disclosed. The split solid adsorption cooling system includes a first adsorption unit, a second adsorption unit, and a shell-and-tube heat exchanger. The first and the second adsorption units are connected to each other via a first pipeline and a second pipeline of the shell-and-tube heat exchanger. While adsorption and desorption take place alternately in the first and the second adsorption units, the temperature of the first and the second pipelines is lowered, thereby decreasing the temperature of water flowing in the shell-and-tube heat exchanger. In addition, the manufacturing costs of the split solid adsorption cooling system can be lowered because the shell-and-tube heat exchanger need not be operated in a vacuum environment. Furthermore, as the shell-and-tube heat exchanger is separate from the first and the second adsorption units, the overall system volume is reduced.

In an air conditioner ( 1 ), a determining part ( 43 ) of a control unit ( 4 ) determines that the amount of frost attaching onto an outdoor heat exchanger ( 13 ) is increased when a difference between an outdoor temperature To and an outdoor heat exchanger temperature Te is increased, and executes a frost attaching condition operation control for reducing the rotation speed of an outdoor fan ( 23 ). The operating frequency of the compressor ( 11 ) is herein increased in accordance with the reduction amount of the temperature of an indoor heat exchanger ( 15 ). The control unit ( 4 ) includes change amounts preliminarily set for changing the operating frequency of the compressor ( 11 ) in stages. The change amounts correspond to the stages on a one-to-one basis. The control unit ( 4 ) increases the operating frequency of the compressor ( 11 ) by corresponding one of the change amounts required for upgrading a present stage of the operating frequency of the compressor ( 11 ) to a stage immediately higher than the present stage every time the temperature of the outdoor heat exchanger ( 15 ) is reduced by a predetermined amount, and reduces the rotation speed of the outdoor fan ( 23 ) in accordance with the change amount.

A highly efficient condensate-free cooling unit functionally based on vapor-compression refrigeration cycle has been described. The condensate collected from the evaporator of the cooling unit is routed through a sub-cooling heat exchanger where it exchanges heat with the primary heat exchange medium emerging through the condenser of the cooling unit, thus, sub-cooling the primary heat exchange medium to a lower temperature before it enters the expansion valve. Emerging from the sub-cooling heat exchanger, the condensate flows through a condensate outlet pipe into multiple spray nozzles disposed over the condensate outlet pipe. The spray nozzles sprinkle the condensate over the hot air blown into the condenser to reduce its temperature. The cooling unit has a substantially higher coefficient of performance compared to the conventional cooling units utilizing vapor-compression refrigeration cycle, and eliminates the problems of condensate removal persistent in the art.

The out of phase electric signals produce electric fields that bias the electrocaloric effect material of one heat transfer stack to a hot phase, emitting thermal energy, while biasing the electrocaloric effect material of an adjacent heat transfer stack to a cold phase, absorbing thermal energy. The thermal distribution layer allows for thermal energy from the material in the hot phase to be distributed to the material of the adjacent stack in the cold phase rather than back to the heat source.

The ejector mass flow multiplier refrigeration cycle utilizes a single-phase ejector which is operated at a high entrainment ratio and performs the function as a mass flow multiplier. The high-pressure motive force input into the single-phase ejector is provided by a vapor compressor which sucks a portion of the output mass flow from an evaporator with the remaining mass flow output from the evaporator being sucked into low-pressure port of the same single-phase ejector. The low-pressure output of the single-phase ejector is inputted into the low-pressure port of a two-phase ejector where the mass flow pressure is increased for the temperature conditions of a condenser. A high-pressure liquid pump provides the motive force input of the two-phase ejector and for the input to an evaporator where the cooling effect of the system takes place.

An air-conditioning apparatus uses a zeotropic refrigerant mixture, in which its saturated liquid refrigerant temperature is lower than the saturated gas refrigerant temperature under the same pressure condition, as the heat source side refrigerant. When one or some of a plurality of heat exchangers related to heat medium functions as an evaporator, the air-conditioning apparatus executes an anti-freezing control that prevents the heat medium from freezing by estimating occurrence of freezing of the heat medium on the basis of a value obtained by subtracting a freezing temperature correction value that is set as a positive value larger than zero from an evaporating temperature of the refrigerant in the heat exchanger related to heat medium.
