In the present embodiment, the 1st auxiliary refrigerant can be using R-407c, R-507a etc., firm as secondary refrigerant
When flowing into 1-1 heat exchangers 213, the temperature of the 1st auxiliary refrigerant is -65 DEG C, is just flowed out from 1-1 heat exchangers 213
When, the temperature of the 1st auxiliary refrigerant is -75 DEG C.This and the 1st auxiliary refrigerant when just flowing into 1 unit cooler 223
Temperature is -75 DEG C, and it is identical meanings that the temperature of the 1st auxiliary refrigerant when just being flowed out from the 1st unit cooler 223 is -65 DEG C.
Load of such 1st unit cooler 223 as the 1st auxiliary refrigerant of the inside for cooling down logistics warehouse
Use, be one kind of cooling and heating load.
That is, multiple 1st unit coolers 223 can to the ice cream warehousing storage in logistics warehouse, F grades of refrigerator, SF grades
The supply such as refrigerator (used at ultra-low temperature), processing factory's refrigerator, extremely low temperature research department is cold and hot.
As described above, the 1st refrigerant circulation pipe arrangement transmits most cold via the 1st auxiliary refrigerant cycle pipe arrangement to logistics warehouse
It is cold and hot.
In order to transmit cold and hot to logistics warehouse with heat exchange is carried out with the LNG of heat exchanger 132 by the 2nd load, if
It is equipped with the 2nd refrigerant circulation pipe arrangement.
2nd refrigerant circulation pipe arrangement is formed in the 2nd load heat exchanger 132, the 2nd refrigerant storage tank the 231, the 2nd and makes
The pipe arrangement that refrigerant cycle pump 232, the 2nd unit cooler 233, the 2nd load are circulated with heat exchanger 132.
In the present embodiment, the 2nd refrigerant can be handed over using R-407c, R-507a etc. just to flow into the 2nd load heat
During parallel operation 132, the temperature of the 2nd refrigerant is -5 DEG C, when just being flowed out with heat exchanger 132 from the 2nd load, the temperature of the 2nd refrigerant
Degree is -10 DEG C.That is, the temperature of the 2nd refrigerant when just having flowed into 2 unit cooler 233 is -10 DEG C, just cold from Unit the 2nd
The temperature of the 2nd refrigerant when but device 233 flows out is -5 DEG C.
Load of such 2nd unit cooler 233 as the 1st auxiliary refrigerant of the inside for cooling down logistics warehouse
Use, be one kind of cooling and heating load, multiple 2nd unit coolers 233 can be to the file custodial warehouse in logistics warehouse, processing
The supply such as the air-conditioning of factory, C2 grades of refrigerator is cold and hot.
As described above, the 2nd refrigerant circulation pipe arrangement is directly cold and hot to logistics warehouse supply.
As described above, the system supplies to required place a small amount of LNG by place's supply line 111 needed for gaseous state LNG, now
To make the gaseous state LNG of generation q.s, i.e., in order to improve the conversion ratio to gaseous state LNG of the liquid LNG in LNG storage tank 100,
Make liquid LNG pass through the 1st, the 2nd load heat exchanger 131,132 discharge it is cold and hot, and thus make liquid LNG temperature heat up or
Person makes liquid LNG gasification, and makes logistics warehouse etc. using the cold and hot of LNG in the 1st, the 2nd load heat exchanger 131,132
Cooling.
That is, liquid LNG through overload with heat exchanger 131,132 during temperature rise or gasify, so as to gas
The conversion ratio of state LNG is improved.
In addition, need to logistics warehouse supply it is substantial amounts of it is cold and hot in the case of, by load heat exchanger 131,132
And LNG is liquefied to the cold and hot of load supply q.s and in re-liquefied device, so as to prevent being generated excessively in LNG storage tank
Gaseous state LNG.Based on the insight that, re-liquefied device only drives when necessary.
According to such system, LNG storage tank 100 of enough sizes can be built and by a small amount of gaseous state in each area
LNG is expelled to required place, on the other hand can actively use the cold and hot popularization thus, it is possible to expand LNG excessive in liquid LNG.
