Abstract

<P>PROBLEM TO BE SOLVED: To provide a sub-cooler used for a cooling system and a method for manufacturing the same to solve the problem of warm waste air of the cooling system. <P>SOLUTION: The sub-cooler is set on the way of the warm waste air after using for cooling an outdoor unit. Thin pipes are respectively diverged from high/low pressure pipes connected to a main cooler from a compressor, and are connected to the sub-cooler. The temperature around the outdoor unit is lowered by lowering the temperature of the warm waste air from the outdoor unit by 1-5°C and exhausting the air. The heat exchanger effectiveness is increased, and the amount of the electric power use can be reduced. Therefore, the urban warm temperature trend and the cooling efficiency can be improved, and the unpleasantness at tropical night can be reduced. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
(Technical field to which the invention belongs)
The present invention relates to a sub-cooler used for a cooling device for the purpose of eliminating warm waste air from the device and a method for manufacturing the sub-cooler.
[0002]
(Conventional technology)
In a conventional cooling device, cooling is performed by repeating this cycle in which a refrigerant is compressed by an outdoor unit, sent to an indoor unit to take indoor heat, returned to the outdoor unit and exchanged heat again. However, the problem is that the hot air from the outdoor unit is a problem. As the saying goes, Chile is accumulating and the temperature and humidity of the atmosphere in urban areas are increasing.
[0003]
(Problems to be solved by the invention)
In recent years, air conditioners have become very popular. You can spend cool and comfortable inside the room, but the outside of the room is scattered by the exhausted air from the air conditioner, which is making you feel uncomfortable in a balmy tropical night. We positioned warming in urban areas, where the population is concentrated, as urban warming. First, we thought it was urgent to eliminate this urban warming and filed this application.
[0004]
(Means for solving the problem)
In order to solve the problems described in the above (0002) and (0003), the present invention provides a subcooler (1) according to (claim 1) in the existing outdoor unit like the improved structure of FIG. When installed in the system and operating through refrigerant, the waste air temperature can be kept lower than when operating as is.
[0005]
(Embodiment of the invention)
The present invention installs a sub-cooler on the path of the warm waste air after being used for cooling the outdoor unit, exits from the compressor, and branches a thin pipe from each of the high-low pressure pipes connected to the main cooler. And connect to this sub-cooler.
[0006]
By lowering the temperature of the waste air from this outdoor unit once to five degrees and discharging it, the temperature around the outdoor unit will decrease, the heat exchange rate will increase, and it will lead to energy saving of energy consumption, urban warming Leads to improved It improves cooling efficiency and reduces discomfort during tropical nights.
[0007]
And the operation is performed by flowing the refrigerant.Until now, only the hot and unpleasant waste wind came out, but the temperature of the waste wind falls once or twice, so the refrigerant on the primary side of this small heat exchanger Provide a fine adjustment valve to adjust the flow rate.
[0008]
(Object of the invention)
In the summer, most homes operate their air conditioners as the temperature rises. A significant number of air conditioners are expected to be in operation in the summer, as evidenced by the power consumption each summer. We applied for the countermeasures, considering the outdoor exhaust of this air conditioner as one of the causes of urban warming.
[Brief description of the drawings]
[Figure 1] As shown, the upper left of the air conditioner outdoor unit improvement diagram is a cross-sectional view of the structure before the improvement. In this way, the cooling air flows in the direction of the arrow, but if it is the same as it is, the ambient temperature will continue to rise.
The upper right of the air conditioner outdoor unit improvement diagram is a cross-sectional view of the structure after the improvement, showing the installation position of the subcooler (1). In this way, the cooling air flows in the direction of the arrow, but the waste air temperature can be reduced compared to before the improvement.
The figure below the air conditioner outdoor unit improvement diagram is a simplified piping diagram inside the outdoor unit.
Connect the high-pressure output from the compressor to the indoor unit and sub-cooler, return from the indoor unit and sub-cooler, connect the low-pressure output to the main cooler, and apply the low-pressure output from the main cooler to the compressor. Connect to and return refrigerant gas.

Claims (2)

An air conditioner system equipped with a sub-cooler (1) on the exhaust side to eliminate warm waste air discharged from the outdoor unit. A fine adjustment valve (2) is provided on the high pressure side of the connection to the subcooler (1) for adjusting the exhaust gas temperature (claim 1).
