Cross heat absorbing heat exchanger.
In various implementations, in order to power to container, the power supply line for being connected to external power supply can (does not show
Out).For example, external power supply may be from carry container ship truck-trailer or may be from container be stored in it is therein
Facility or place.In addition, container can be with generator 60 (Fig. 3, such as with internal combustion engine) correlation.For conventional container, hair

It is a.
Exemplary system 30 is section hot type system.Exemplary section hot type system has compressor as split-compressor,
With corresponding first order 36A and second level 36B.In an exemplary embodiment, first order 36A and second level 36B are respectively
Low-pressure grade and pressure level.Exemplary stage is usually powered by motor 37.For example, grade can be the independent of reciprocating compressor
Cylinder group.Fig. 3 shows the compressor with total suction inlet 90 and total outlet 92.Economizer mouth is denoted as 94.Exemplary section
Hot device is related to the flash tank economizer subsystem 100 between heat rejection heat exchanger 38 and expansion device 40.Exemplary system 100
Including having for feeding the liquid outlet 104 of expansion device 40 and for feeding saturated vapor along economizer pipeline 108
To the flash tank 102 of the steam (vapor) outlet 106 of economizer mouth 94.In general, the mixing of saturated vapor helps cooling (reduction) to leave the
The temperature of the refrigerator of level-one.This and the intercooler are together for reducing that temperature to prevent (the exhaust of second level temperature
Temperature) become too high.Economizer expansion device 110 can be integrated with flash tank or the upstream of the entrance 112 in flash tank.
Exemplary expansion device 110 is conventional high-pressure power expansion valve.
Exemplary refrigeration system is also the component cooling system with intercooler heat exchanger 120.Intercooler heat exchanger can be
In some operation modes between the first order 36A and second level 36B along refrigerator flow path.Exemplary intercooler heat exchanger
(intercooler) 120 is refrigerant-air heat exchanger.Exemplary refrigerant-air heat exchanger is along outside air flow path 508.
In an exemplary embodiment, intercooler heat exchanger 120 is along the flow path 508 in the downstream of heat rejection heat exchanger 38.It is as follows
What face further discussed, heat exchanger 38 and 120 can be integrated in separated pipe leg 124 associated with heat exchanger 38 and with change
In single air-cooled condenser/intercooler unit 121 (Fig. 6) of the associated pipe leg 126 of hot device 120.Example combinations unit
It is finned tube heat exchanger (such as round tube plate fin (RTPF)), wherein metal wing 128 and tube sheet are shared by two groups of pipe legs.Other configurations
Pipe can be made to mix, and pipe associated with respective leg cuts flat with weighing apparatus really and can be determined by various performance factors.
Intercooler is positioned to along pipeline 130 (Fig. 3) between the grade of leg 34-1 between the grade for forming flow path 34.Pipeline is from pressure between grade
Mouth 134 on contracting machine extends.In exemplary middle cold type and section hot type embodiment, intercooler pipeline 130 and economizer pipeline
108 merge, so that intercooler refrigerant stream can return to the second level via economizer mouth 94.
It may be conventional multiple additional features that Fig. 3, which is shown in baseline section hot type and middle cold type system,.These include edge
The valve 140 of economizer pipeline (such as economizer solenoid valve), optionally allow and prevent economizer stream.Along section
The check-valves 142 of hot device pipeline prevents the adverse current by mouth 106.Feather valve 144 (such as emptier solenoid valve) is positioned to edge
The ballast line 146 of first order entrance (suction inlet 90) condition is extended back into from second level entrance (section hot type mouth) condition.?
In exemplary implementation scheme, this is shown as at the junction of pipeline 108 and 130 and between the suction line of 90 upstream of suction inlet
Extend.Physical layout other than those of shown arrangement can realize identical jet stream condition.
Other general characteristics first is that filter/dryer 150, high side charge port 152, downside charge port 153, downside pressure
Power relief valve 154, high side pressure relief valve 156, various pressure sensors 158, various temperature sensors 160 and flashing pressure are released
Put valve 162.
System 30 by along refrigerant flow path the upstream of heat rejection heat exchanger 38 water-cooled heat rejection heat exchanger 170 (also known as
Water cooled condenser) it is added to exemplary baseline refrigeration system.Water flow road 172 is placed in by heat exchanger 170 to be flowed through with refrigerant
In commutative relation.Although using term " water " as actual contents, the stream in flow path 172 is generally not pure water, but can be with
With one or more of the various additives for bacterial control, corrosion inhibition, cryoprotection, pump lubrication etc..This water
It is identified as " buck " in the art.Fig. 3 shows the inlet fitting 174 and outlet accessory 176 along flow path 172.Hydraulic pressure passes
Sensor 178 can be along flow path 172 between the fittings somewhere.As discussed below, these can be via corresponding accessory
184,186 (such as automatic water drain type quick coupling fittings) are connected to corresponding supply line 180 and return line 182 to supply
Cold water simultaneously returns to hot water.Incorrect link in order to prevent, accessory 174 and 176 may differ from each other, such as with opposite gender.
System 30 can have one or more non-water cooling modes, without the stream along flow path 172.These may include one
A or multiple section heat patterns and one or more non-section heat patterns.
System 30 also has at least one mode, wherein there is the water flow along flow path 172.As discussed below, this is for example
When container aboard ship when will occur.It is poor due to recycling in the case where container stacks are in ship, along flow path 508
Inlet air flow can have relatively hot air.Due to lacking the heat extraction via heat exchanger 170, system 30 may not be at that
Keep container cooling in a little situations.Similarly, otherwise extreme outdoor temperature may overwhelm the basic capacity of system.Such
In the case of, the refrigerant into heat exchanger 38 is pre-cooled along the stream of flow path 170.According to circumstances, this cooling can arrive
Lower than the temperature of ambient air temperature.
In general, control can usually reflect water-cooled frozen products insulated container and section hot type/middle cold type container existing control association
View.Such as in conventional water cooled system, pressure sensor 178 can be by controller using determining when to be switched to water cooled mo(u)ld
Formula.When threshold value hydraulic pressure is sensed, the power of condenser fan 50 is can be cut off in controller, while continuing to operate normally compression
Machine, evaporator fan and other components.When hydraulic pressure is not sensed, controller is by normal operating condenser.
The cooling of refrigerant into heat exchanger 38 allows along the indirect cold of the intercooler flow path 34-1 refrigerant passed through
But.For example, not being to expel the heat to air stream 520, heat exchanger 38 can absorb heat from air stream 520 and allow intercooler heat exchanger
120 expel the heat to air stream 520 again.Another mechanism or dynamics be via heat from intercooler heat exchanger to heat exchanger 38 it is straight
Connect heat transfer.As mentioned above, heat exchanger 38 and 120 can be two sections of single physical unit.For example, individual unit can
To be plate-fin heat exchanger, wherein the two sections are formed by different independent pipe legs 124,126 (Fig. 7), but share wing 128.Wing
Heat can be transmitted to the pipe of heat exchanger section 38 from the pipe of intercooler heat exchanger section.In this case, fan 50 can close with
Prevent air stream 520.It is therefore seen that by the upstream that water cooled condenser 170 is located in air cooled condenser 38, water-cooled
Condenser 170 can provide the direct cooling and refrigerant along intercooler flow path the indirect cooling of the refrigerant along primary flow path
To allow the middle cold type in water cooling mode to operate.This avoids for example to the second water cooling provided along intercooler flow path 34-1
The needs of formula heat exchanger.
