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:
An absorption pipe structure of a compressor, capable of reducing vibration of the absorption pipe and making the machinery room small-sized, by making short the length of the absorption pipe connected with the compressor and forming the curved part formed in a proper diameter, is provided.
Abstract:
Disclosed is a structure of an outdoor unit in an air conditioner, capable of reducing vibration of the pipes even more, by providing a damping member (16) for making different pipes connected each other so that the vibration system of the pipes inside the machinery room may be changed.
Abstract:
The present invention relates to a ventilator. Channels are horizontally extended in the interior of a total heat exchanger. The channels are vertically stacked for thereby enhancing the efficiency of heat exchange.

Abstract:
Provided is an improved blower fan structure in which length of blades is increased and inlet and outlet angles of the blades are optimized for highly increasing an efficiency of the blower fan. Particularly, an outer diameter of the blades is more than or equal to two times of an inner diameter thereof, for increasing the efficiency without generating a noise.
