Abstract
Description
図4(A)は、変形例1に係る冷凍装置1の外観を模式的に示す正面図である。変形例1に係る冷凍装置1は、断熱箱体2と、第1の貯蔵室510と、第2の貯蔵室520と、機械室600とを有する。例えば、第1の貯蔵室510と第2の貯蔵室520とは、互いに断熱されている。そして、第1の貯蔵室510は、冷媒回路400の蒸発器408によって冷却される。一方、第2の貯蔵室520は、第1のサーマルサイフォン200によって冷却される。すなわち、第1のサーマルサイフォン200の第1の凝縮部210(図1参照)と蓄冷式冷凍機100の吸熱部160(図1参照)との間で熱交換して、第1の凝縮部210内の冷媒が冷却され凝縮する。そして、第1の蒸発部240における冷媒の蒸発によって第2の貯蔵室520が冷却される。
図4(B)は、変形例2に係る冷凍装置1の冷媒回路における凝縮器404近傍を模式的に示す図である。変形例2に係る冷凍装置1では、蓄冷式冷凍機100の吸熱部160が、冷媒回路400の凝縮器404に直に接する。すなわち、第2のサーマルサイフォン300を介さずに、吸熱部160と凝縮器404との間で熱交換がなされる。このような構成によっても、実施の形態と同様の効果を奏することができる。また、第2のサーマルサイフォン300を省略することで、冷凍装置1の構造をより簡略化することができる。
402 圧縮機、 404 凝縮器、 408 蒸発器、 500 貯蔵室、 510
第1の貯蔵室、 520 第2の貯蔵室。
