To install the 8000RT refrigerator, 4 spaces of 6000mm x 12000mm were required, but only 2 spaces of 6000mm x 12000mm are enough to install the 8000RT. 2 is enough. Moreover, since the group of low temperature cylinders was connected to the regenerator and the condenser in parallel via the rare absorption liquid pipe, the concentrated liquid pipe, and the refrigerant pipe, operation and stop were controlled for each group of low temperature cylinders to cause large fluctuations in load. It becomes possible to easily deal with. In addition, since the group of high temperature and medium temperature cylinders was connected to the absorber in parallel via the rare absorption liquid pipe and the concentrated liquid pipe, each high temperature,
It is also possible to easily respond to a large change in load by controlling the operation and stop for each group of medium-temperature cylinders. Furthermore, multiple groups of low temperature cylinders and multiple groups of high temperature and medium temperature cylinders installed in different areas are connected in parallel by absorbing liquid refrigerant piping for each group, so that each low temperature cylinder can respond to large changes in load. It controls the operation and stop for each group of, and operates for each group of high temperature and medium temperature cylinders corresponding to each group of low temperature cylinders,
It controls the stop and easily responds to load fluctuations.
It is possible to avoid wasteful operation between each low temperature cylinder group and each high temperature and medium temperature cylinder group corresponding to each low temperature cylinder group, and improve the operation efficiency. Further, by installing a plurality of low temperature cylinders, it is possible to simplify the water piping work and minimize the piping arrangement.
Moreover, it also simplifies on-site assembly work.
