Abstract: A heat pump according to the present invention comprises a plurality of the compression chambers, and compresses refrigerant with multistage, and injects vapor refrigerant into the space between the plurality of the compression chambers by using the first refrigerant injection flow path and the second refrigerant injection flow path. Performance and efficiency of the heat pump can be improved compared with non-injection, as flow rate of the refrigerant circulating the indoor heat exchanger is increased. Thus heating performance can be improved also in the extremely cold environmental condition such as the cold area by increasing the injection flow rate. Also, because the heat pump according to the present invention comprises the first refrigerant injection flow path and the second refrigerant injection flow path, refrigerant is injected twice. Thus, as the injection flow rate of the refrigerant is increased, heating capacity can be improved. Also, the difference between the suction pressure and the discharge pressure of the rotary compressor may be decreased, and thus the reliability and the performance of the rotary compressor can be improved.

Abstract: A precooler/chiller/reheater (PCR) system comprising a precooler/reheater counterflow heat exchanger and a chiller counterflow heat exchanger separated by a moisture removal section. Refrigerant is flashed through a perforated distribution manifold along the plates of the chiller. Warm, moist air is precooled in the precooler/reheater heat exchanger. A manifold conveys the precooled air to the chiller heat exchanger. Chilled air exits the chiller at a low point in the system. Moisture condensed in the precooler and chiller drains into a sump that also acts to convey air into the moisture removal section. Water droplets are stripped from the airflow and drain downwards into the sump. The chilled and dried air is conveyed to the second side of the precooler/reheater heat exchanger and passes downward in counterflow to the direction of air entering the system on the first side of the heat exchanger, then exits the system ready for use as reheated, dried air.

Abstract: The invention is a device that allows the manipulation of both the temperature and the humidity of air through the temperature control of two fluid volumes, one of which must be water. Air may be pumped or forced through a volume of water to humidify it. That same air may then be passed over a collection of tubing with a high thermal conductivity containing a cold fluid to chill the air and allow condensation to occur. By this method, air will be dehumidified. Dehumidification can be augmented by the addition of a valve to effect pressurization within the device. The air is then passed through a system of pipes that run through the volume of water responsible for humidification to give the air its final temperature. The heating of the two volumes of water can be done through the same means as air is heated in the place of installation.

Abstract: An air conditioner for a vehicle has a heat pump type refrigerant circuit capable of operating at least in a heating mode. The air conditioner comprises a motor fan for supplying air heated by a heat exchanger to the interior of the vehicle during operation of the heating mode, a sensor for detecting the temperature of the air at a position downstream of the heat exchanger and a control unit for controlling the volume of the air supplied by the motor fan to a predetermined minimum volume by controlling the drive of the motor fan when the detected air temperature is lower than a predetermined temperature. Even in a condition where a sufficiently large heat radiation from the heat exchanger cannot be expected, a large volume of cold air that has been insufficiently heated can be prevented from being discharged into the interior of the vehicle. Because the motor fan is driven at a condition of minimum air volume even when the detected temperature is lower than the predetermined temperature, a rapid variation of air volume caused at the time of changing a fan-stopping condition to a fan-driving condition can be avoided and an abnormal increase in the discharge pressure of the heat pump compressor can be prevented.
