本発明は、空冷ヒートポンプ式空気調和機の改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement in an air-cooled heat pump type air conditioner.
熱交換器の形式としては、一般的に受熱媒体と放熱媒体
の流れ方から区別される平行流と対向流とがある。There are generally two types of heat exchangers: parallel flow and counterflow, which are distinguished based on the flow of the heat receiving medium and the heat dissipating medium.
この二つの形式のうち、ヒートバランス上、平行流よシ
も対向流の方が、熱交換効率が優れている。Of these two types, in terms of heat balance, both parallel flow and counterflow have better heat exchange efficiency.
又、熱交換効率を左右する要因として、熱交換器内を流
れる熱交換媒体の流速があり、この流速が速い程熱交換
効率が向上する。Further, a factor that affects heat exchange efficiency is the flow rate of the heat exchange medium flowing inside the heat exchanger, and the faster the flow rate, the better the heat exchange efficiency.
従って、空気調和機に使用される熱交換器も、冷房暖房
時の両方において、対向流形式がよく、かつ、熱交換器
内を流れる熱交換媒体の流速を速くする方がよい。Therefore, it is preferable for the heat exchanger used in an air conditioner to be of a counter-flow type, and to increase the flow rate of the heat exchange medium flowing through the heat exchanger, both during cooling and heating.
従来より、冷房及び暖房時において、共に対向流となる
ように、一方向冷凍サイクルが採用されている
。Traditionally, a one-way refrigeration cycle has been used to provide countercurrent flow during both cooling and heating.
.

時に共に対向流とするために、圧縮機の吐出側と吸込み
側とにそれぞれ四方弁を設け、かつ、各熱交換器の熱交
換媒体の入口側と出口側のそれぞれに、逆止弁を設けて
いた。However, in this one-way refrigeration cycle, four-way valves are provided on the discharge side and suction side of the compressor to create counterflows during both cooling and heating, and the heat exchange medium of each heat exchanger is A check valve was installed on each of the inlet and outlet sides.
そ−の結果、配管途中における圧力損失が大きくなり、
その分だけ、熱交換器内を流れる熱交換媒体の流速が低
下し、圧縮機の出力に対する空気調和機の性能が低下す
るという欠点があった。As a result, the pressure loss in the middle of the piping increases,
The flow rate of the heat exchange medium flowing through the heat exchanger decreases accordingly, resulting in a disadvantage that the performance of the air conditioner relative to the output of the compressor decreases.
本発明は、上記従来の欠点を解決するためになされたも

ある。The present invention has been made in order to solve the above-mentioned conventional drawbacks.It also enables counterflow during cooling, heating, and defrosting, and furthermore, minimizes the number of valves installed in the middle of piping. The object of the present invention is to provide an air-cooled heat pump type air conditioner that reduces pressure loss and further improves performance.

れている。In this refrigeration cycle, during cooling, the high-temperature, high-pressure gas refrigerant discharged from the compressor 1 is passed through the port of the six-way valve 8.
It passes through b and condenses at the outdoor heat exchanger (air side heat exchanger) 2 from the branch point g to become a high-temperature, high-pressure liquid refrigerant, and reaches the branch point g. Between the branch point and e of the six-way valve 8 is the cylinder 1 of the six-way valve 8.
0 and the piston 11 are in the closed state, the refrigerant does not flow and passes through the check valve 7 from the branch point to the pressure reducing device 6.
leading to. Here, the pressure is reduced and the low-temperature, low-pressure unsaturated liquid refrigerant reaches a branch point IVc. Between branch point i and C of six-way valve 8 is six-way valve 3
(IF') Shi IJ 7 da 10. Since the piston 11 is in the closed state, the refrigerant does not flow and reaches the branch point i.
The refrigerant then exchanges heat with the indoor heat exchanger (water-side heat exchanger) 3, becomes a low-temperature, low-pressure gas refrigerant, passes through the branch point j, passes through the port of the six-way valve 8), df, and returns to the compressor 1. During heating, the six-way valve 8 is in the state shown in FIG. 2 during heating. The high-temperature, high-pressure gas refrigerant discharged from the compressor 1 is passed through the port of the six-way valve 8) a)
-C, from the branch point i, condenses in the indoor heat exchanger (water side heat exchanger) 3 to become a high temperature and high pressure liquid refrigerant, and turns to the branch point jrc.
reach. Since the cylinder 10 and piston 11 of the six-way valve 8 are in a closed state between the branch point j and the six-way valve 8, the refrigerant passes through the check valve 5 from the branch point j and reaches the pressure reducing device 4. Here, the pressure is reduced and the low-temperature, low-pressure unsaturated liquid refrigerant reaches a branch point g. Since the cylinder 10 and piston 11 of the six-way valve 8 are closed between the branch point g and the six-way valve 8, the refrigerant does not flow, and the refrigerant flows from the branch point g to the outdoor heat exchanger (air side heat exchanger). ) 2, the refrigerant becomes a low-temperature, low-pressure gas refrigerant, passes through the branch point, passes through the hexagonal valve 8 (bow) e - f, and returns to the compressor 1. During defrosting, the cycle is exactly the same as during cooling. According to this embodiment, the refrigerant flow path to the heat exchanger is unidirectional during both cooling and heating, and is arranged so as to flow in a direction opposite to the air flow and the water flow.

As a result, the pressure loss in the piping system is reduced, and the discharge pressure of the compressor 1 is reduced by the pressure difference between the inlet and outlet of the heat exchange medium of the indoor and outdoor heat exchangers 2 and 3 (the pressure difference between the inlet and outlet of the heat exchanger). Since the heat medium flows due to the pressure difference, the larger the pressure difference, the faster the flow rate and the better the heat exchange efficiency.

できた。As detailed above, according to the air-cooled heat pump type air conditioner according to the present invention, the outdoor heat exchanger and the indoor heat exchanger are configured to have opposite flows even during cooling and heating by using a hexagonal valve. , the number of check valves in the cooling cycle system and the heating cycle system is minimized to one to reduce the pressure loss in the piping system, so the discharge pressure of the compressor is not consumed as pressure loss in the piping system. It can be effectively used as a differential pressure between the inlet and outlet of an indoor or outdoor heat exchanger, increasing the flow rate of the heat exchange medium flowing inside the heat exchanger, and the synergistic effect with the counterflow improves cooling and heating performance. I was able to improve significantly.

きた。In addition, since only one six-way valve is required compared to the conventional four check valves and one four-way valve, the number of parts is significantly reduced, resulting in fewer failures and improving the reliability of the refrigeration cycle. At the same time, the refrigeration cycle is simplified, which reduces assembly man-hours, lowers the cost, and improves product value.
