The utility model content
The purpose of the utility model is to provide a kind of double Shell negative pressure absorption refrigeration air-conditioning equipment, to reduce the complexity of vacuum envelope, reduces material and processing cost greatly.
The design of the utility model is that the seal request of system's solution and vacuum are required to realize with internal layer shell and outer casing respectively; The corrosion of avoiding outer casing to contact with solution; Thereby avoid contaminated aqueous solution; Thereby reduce the material and the manufacturing cost of negative pressure absorption refrigeration air-conditioning equipment greatly, improve long-time running efficient.
The technical scheme that the utility model is implemented is: a kind of negative pressure absorption refrigeration air-conditioning equipment; Comprise generator, condenser, absorber and evaporimeter; Flow between generator, condenser, absorber, evaporimeter system's solution is arranged; At least one of generator, condenser, absorber and evaporimeter or a plurality of being built in the vacuum seal housing; It is characterized in that the vacuum seal housing comprises the internal layer shell that is used for sealing system solution and be used for vacuum-packed outer casing that non-common sparing forms the vacuum interlayer that has or not system's solution between internal layer shell and outer casing.
Described negative pressure absorption refrigeration air-conditioning equipment, its further characteristics be, outer casing and internal layer shell be two independently, isolated continuous housing fully each other.
Described negative pressure absorption refrigeration air-conditioning equipment; Its further characteristics are; Internal layer shell connects common housing by discrete housing and forms; This common housing is the housing of generator, condenser, absorber or evaporimeter, or other heat exchanger wall of negative pressure absorption refrigeration air-conditioning equipment, the perhaps part of outer casing.
Described negative pressure absorption refrigeration air-conditioning equipment, its further characteristics are that the said discrete housing of internal layer shell is the corrosion resistant plastic casing of waterproof or rubber shell or metal shell.
Described negative pressure absorption refrigeration air-conditioning equipment; Its further characteristics are; Internal layer shell and outer casing all have process channel and atmosphere; The process channel of internal layer shell adopts valve closing or direct welded closure, outer vacuum seal housing and the direct welded closure of atmosphere passage or the technology mouth that adopts valve closing and get rid of as incoagulable gas.
The material of outer casing is suitable vacuum-packed metal, like carbon steel, aluminium alloy etc. or suitable vacuum-packed nonmetal, like glass etc.The material of internal layer shell is the material of the anti-fluid seepage of anticorrosion, like plastics, rubber or stainless steel etc.
Because the vacuum seal housing comprises the internal layer shell that is used for sealing system solution and is used for vacuum-packed outer casing; Non-common sparing forms the vacuum interlayer that has or not system's solution between internal layer shell and outer casing, and therefore the sealing with system's solution separates with vacuum sealing function, reaches the complexity that reduces vacuum envelope; Reduce material and processing cost greatly; Simultaneously, contaminated aqueous solution is avoided in the corrosion of avoiding outer casing to contact with solution; Thereby reduce the material and the manufacturing cost of negative pressure absorption refrigeration air-conditioning equipment greatly, improve long-time running efficient.Adopt the double-layer shell structure of outer casing carbon steel internal layer shell plastics, adopt stainless steel to obtain total housing cost decline 60%-80% of same anti-solution corrosion effect fully than single hull.Simultaneously, this structure is also simplified the product assembling process greatly, enhances productivity.
