Description
図1はこの発明の実施の形態1の冷凍冷蔵庫の冷媒回路図、図2は図1による冷凍冷蔵庫の側面断面図である。この冷凍冷蔵庫の冷凍サイクルの冷媒には地球温暖化に非常に影響が小さい炭化水素系冷媒R600aを用いている。図において、1は内部に電動機を有し、この電動機にて駆動される高段側圧縮部2と低段側圧縮部3より構成される圧縮機、4は圧縮機1の吐出側から配管で接続された凝縮器、5は凝縮器4の流出側に接続された熱伝達手段である過冷却熱交換器、6は過冷却熱交換器5と冷却器上流に位置する絞り装置の毛細管との間に配管接続された流路切換手段である電動流路切換弁であり外部からの電気信号により流路を連通または閉止することができる。圧縮機1は外部の指令により、電動機の回転数を制御できるインバータ方式の圧縮機であり、この図では内部は低圧に保持されている。
Claims (6)
- 密閉容器内に電動機により駆動される低段側圧縮部と高段側圧縮部からなる圧縮要素を有した圧縮機、凝縮器、第一の膨張手段、前記第一の膨張手段と並列に接続された第二の膨張手段、前記第一の膨張手段の出口側に接続された冷蔵用冷却器および前記第二の膨張手段の出口側に接続された冷凍用冷却器と、

- 前記熱伝達手段を二重管熱交換器としたことを特徴とする請求項1または2に記載の冷凍冷蔵庫。
- 前記熱伝達手段は、前記凝縮器出口配管の外側に冷却器出口から接続された吸入配管を巻きつけて構成したことを特徴とする請求項1または2に記載の冷凍冷蔵庫。
- 前記電動機をインバータ駆動としたことを特徴とする請求項1乃至4に記載の冷凍冷蔵庫。
- 前記流路切換手段の弁駆動方式をステッピングモータ駆動としたことを特徴とする請求項1乃至5に記載の冷凍冷蔵庫。
