PURPOSE:To obtain energy saving effect by a method wherein two sheets of interlocking shutters are provided at the upper and lower parts of a glass, faced to the outdoor side of double glass windows equipped with a solar heat collecting blind, so that a space between two sheets of glasses becomes a part of outdoor air flow path. CONSTITUTION:The double glass windows 17a, 17b, equipped with the solar heat collecting blind 18, are provided at the outdoor air suction side of a case 11 accommodating an air-cooled heat pump type refrigerating circuit and the space between two sheets of glasses of the double glass windows is utilized as a part of the outdoor air flow path during room heating operation by the opening and closing of two sheets of interlocking shutters. As a result, atmosphere of low temperature may be heated by utilizing the solar heat and high room heating capacity may be developed without using expensive energy to increase evaporating temperature to increase the room heating capacity whereby the energy saving effect may be obtained. |
