Claims (5)
- 前段圧縮部で圧縮された二酸化炭素冷媒が、一次放熱器を経て後段圧縮部で圧縮され二次放熱器で放熱されたのち膨張装置を経て蒸発器(冷却器)で蒸発する冷凍装置において、前記一次放熱器の入り口側には、振動減衰部分として複数本のキャピラリチューブによって並列の冷媒通路を形成するキャピラリチューブ部分を設けたことを特徴とする冷凍装置。
- 前段圧縮部で圧縮された二酸化炭素冷媒が、脈動低減装置としてのマフラを通り一次放熱器を経て後段圧縮部で圧縮され二次放熱器で放熱されたのち膨張装置を経て蒸発器(冷却器)で蒸発する冷凍装置において、前記マフラの出口側の冷媒通路には、振動減衰部分として複数本のキャピラリチューブによって並列の冷媒通路を形成するキャピラリチューブ部分を設けたことを特徴とする冷凍装置。
- 前段圧縮部で圧縮された二酸化炭素冷媒が、脈動低減装置としてのマフラを通り一次放熱器を経て後段圧縮部で圧縮され二次放熱器で放熱されたのち膨張装置を経て蒸発器(冷却器)で蒸発する冷凍装置であって、前記一次放熱器は、コイル状、蛇行状等に屈曲した屈曲形状をなして、その上部が振動吸収部材を介して吊り下げ保持された構成において、前記マフラの出口側の冷媒通路には、振動減衰部分として複数本のキャピラリチューブによって並列の冷媒通路を形成するキャピラリチューブ部分を設けたことを特徴とする冷凍装置。
- 前記キャピラリチューブ部分は、中間部が下方へU字状に屈曲した又は蛇行状に屈曲した屈曲部を形成し、この屈曲部に前記振動吸収部材を取り付けたことを特徴とする請求項1乃至3のいずれかに記載の冷凍装置。
- 前記前段圧縮部から前記二次放熱器までの部分が冷却貯蔵庫本体下部に設けた機械室内に配置され、前記一次放熱器は、その上部が振動吸収部材を介して前記機械室上部の取り付け部で吊り下げ保持され、前記キャピラリチューブ部分は中間部に振動吸収部材を取り付けたことを特徴とする請求項1乃至3のいずれかに記載の冷凍装置を備えた冷却貯蔵庫。
