Definitions
- the present invention relates to an absorption refrigeration cycle and a compression absorption refrigeration cycle.
- Patent Documents 1 and 2 use ammonia refrigerants that have a low global warming potential but are toxic, requiring countermeasures against refrigerant leakage.
- Patent Document 1 discloses an example in which R134a refrigerant, which is a non-toxic HFC refrigerant, is used, it has a high global warming potential and may become unusable in the future.
- a characteristic configuration of the absorption refrigeration cycle according to the present invention is a refrigerant having a global warming potential of less than 1000 and containing at least one of an HFO refrigerant, an HFC refrigerant, and an HCFO refrigerant, and formulas (1) and (2) ), and an absorption liquid containing at least one of the compounds represented by the formula (3).
- R 1 and R 2 are each independently a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and n is an integer of 1 to 6.
- R 1 and R 2 are each independently selected from the group consisting of a hydrogen atom, a methyl group, an ethyl group, a propyl group, and a butyl group, and n is The point is that it is an integer of 1 or more and 3 or less.
- the circulation ratio in the absorption refrigeration cycle can be reduced, and performance can be improved.
- a characteristic configuration of the compression absorption refrigeration cycle according to the present invention is that any one of the above absorption refrigeration cycles and the compression refrigeration cycle are combined in a manner that shares the refrigerant.
- the air conditioning system 100 has a configuration in which an absorption refrigeration cycle and a compression refrigeration cycle are combined in a manner of sharing a refrigerant.
- the air conditioning system 100 has a high pressure stage 110, a low pressure stage 120, and a gas-liquid separator 130 (FIG. 1).
- the high-pressure stage section 110 is provided with a pump 111, a solution pressure reducing device 112, a solution heat exchanger 113, a regenerator 114, a condenser 115, a refrigerant expansion device 116, and an absorber 117.
