Description
Technical field
The present invention relates to negative pressure absorbing formula refrigeration air-conditioner field.
Background technology
Negative pressure absorbing formula refrigeration air-conditioner is take the lithium bromide absorbing type refrigeration air-conditioning equipment as Typical Representative.This kind equipment is usually used various waste heat thermals source and is freezed or heat take water as refrigerant, comprise generator, evaporimeter, absorber, condenser, throttling arrangement.Its characteristics need to realize in the negative pressure that is lower than atmospheric pressure or vacuum environment for evaporation absorption process and the generation condensation process that produces heat and mass exchange.Existing negative pressure absorbing formula refrigeration air-conditioner is the single layer enclosure structure, and this single layer enclosure structure includes the one or more heat-exchanging parts in condenser, generator, absorber and the evaporimeter as the vacuum seal housing.Liquid, the gas two of the solution of vacuum seal inner walls and system's generation and absorption contact.Simultaneously, dispose the extraction remover of incoagulable gas in the system.Therefore when requiring the shell welded seal to ensure the high vacuum seal performance, system's solution brings following problem to the corrosion danger of shell inboard: at first solution to the corrosion of shell inboard so that system's contaminated aqueous solution, produce more incoagulable gas and reduce systematic function, and may the Partial Blocking system.Secondly, consider that the factor of corroding increases shell wall thickness and causes cost to increase.Perhaps require shell to adopt expensive high-strength corrosion-resisting material such as stainless steel, also can greatly increase equipment cost.
Summary of the invention
The object of the present invention is to provide a kind of double Shell negative pressure absorbing formula refrigeration air-conditioner, to reduce the complexity of vacuum envelope, greatly reduce material and processing cost.
Design of the present invention 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 greatly reduce material and the manufacturing cost of negative pressure absorbing formula refrigeration air-conditioner, improve long-time running efficient.
Technical scheme of the invention process is: a kind of negative pressure absorbing formula refrigeration air-conditioner, 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 that non-common sparing is formed with the vacuum interlayer without system's solution between internal layer shell and outer casing for the internal layer shell of sealing system solution with for vacuum-packed outer casing.
Described negative pressure absorbing formula refrigeration air-conditioner, its further characteristics be, outer casing and internal layer shell be two independently, complete isolated continuous housing each other.
Described negative pressure absorbing formula refrigeration air-conditioner, 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 absorbing formula refrigeration air-conditioner, the perhaps part of outer casing.
Described negative pressure absorbing formula refrigeration air-conditioner, its further characteristics are that the described discrete housing of internal layer shell is the corrosion resistant plastic casing of waterproof or rubber shell or metal shell.
Described negative pressure absorbing formula refrigeration air-conditioner, its further characteristics are, internal layer shell and outer casing all have process channel to be communicated with 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 communicating passage or the technique mouth that adopts valve closing and get rid of as incoagulable gas.
The material of outer casing is suitable vacuum-packed metal, such as carbon steel, aluminium alloy etc. or suitable vacuum-packed nonmetal, such as glass etc.The material of internal layer shell is the material of the anti-fluid seepage of anticorrosion, such as plastics, rubber or stainless steel etc.
Because the vacuum seal housing comprises for the internal layer shell of sealing system solution and is used for vacuum-packed outer casing, non-common sparing is formed with the vacuum interlayer without system's solution between internal layer shell and outer casing, therefore the sealing with system's solution separates with vacuum sealing function, reach the complexity that reduces vacuum envelope, greatly reduce material and processing cost, simultaneously, the corrosion of avoiding outer casing to contact with solution, avoid contaminated aqueous solution, thereby greatly reduce material and the manufacturing cost of negative pressure absorbing formula refrigeration air-conditioner, 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 assembling product process greatly, enhances productivity.
