- the present invention relates to an apparatus and a method for performing a cold vapor process.
- An apparatus for performing a cold vapor process comprises a main engine-driven compressor configured to draw a mass flow of a refrigerant fluid at evaporator pressure level and to compress this mass flow to a high pressure level.
- a high-pressure heat exchanger is provided to the
- Mass flow of the fluid which is at high pressure level, to cool, to increase a density thereof and to reduce a temperature of the fluid by the cooling.
- the coming from the high-pressure heat exchanger mass flow of the fluid is working in an expander on
- Evaporator is designed to absorb heat so that the density of the fluid as it passes through the evaporator decreases and the temperature of the coming of the expander mass flow, which is on
- Evaporator pressure level is and passes through the evaporator rises. Finally, a downstream of the high pressure heat exchanger and the
- Expander upstream subcooler provided. After the subcooler and before the expander part of the mass flow of the fluid, which is located at high pressure level, branched off and by means of a high pressure control valve at medium pressure level, so that the fluid then absorbs heat to mid-pressure level in countercurrent in the subcooler and thereby the mass flow, the at high pressure level, subcooled in subcooler.
- a high-pressure compressor which is mechanically directly connected to the expander, is designed to exclusively control the mass flow of the fluid passing between the subcooler and in front of the expander and countercurrent to that of the subcooler
- High-pressure level is located, guided mass flow of medium-pressure level Compress high pressure level and mix in front of the high-pressure heat exchanger to the mass flow of the fluid coming from the motor-driven main compressor.
- the described device is an efficient control of the high pressure, which is typically applied to the high pressure heat exchanger, the high pressure compressor and partially to the subcooler possible.
- the high-pressure compressor additionally driven directly by the expander compresses only a separate mass flow of the fluid, the medium-pressure mass flow, the mass flow passed through the expander, which comes from the high-pressure heat exchanger, can be additionally subcooled. The exergy of the expansion is thus ultimately used for additional supercooling at high pressure or a performance of the expander serves to compress the medium-pressure mass flow in the high-pressure compressor.
- a collector may be arranged. This is adapted to separate a liquid phase of the fluid and a vapor phase of the fluid.
- the liquid phase of the fluid can be stored in the collector and can be relaxed to evaporator pressure via an injection valve arranged between the collector and the evaporator.
- the vapor phase of the fluid can be relaxed via a pressure-holding valve.
- the expanded liquid phase can be supplied to the evaporator in the mass flow, while the expanded vapor phase after the evaporator can be mixed into the mass flow of the fluid coming from the evaporator.
- the expander and the high-pressure compressor are arranged in a common housing and form a unit, which is also referred to as "expander-compressor unit".
- the arrangement in a single housing allows a space-saving design, in which the expander and the high pressure compressor are mechanically directly, in particular pressure-tight connected to each other.
- a displacement ratio between the expander and the high-pressure compressor should preferably be between 0.5 and 0.75 in order to ensure an optimal course of the cold vapor process. Particularly preferably, the displacement ratio is 0.6. Basically, lower values for high he re-cooling temperatures at the outlet of Hoch Kunststofferiemreübertragres meaningful application.
- working spaces of the expander can be controlled via a main slide and an auxiliary slide.
- the main slide and the auxiliary slide are in this case arranged centrally between the usually inner, ie mutually facing working spaces of the expander.
- the main slide and or or the auxiliary slide are designed as flat slide to ensure a simple and very dense operation with only a small footprint.
- auxiliary slide of working piston is movable by two pins.
- a piston rod which holds the working piston at a distance, releasably connected to the working piston, that is not firmly connected to these.
- This is manufacturing technology simple yet functional, since the internal piston rod experiences only compressive forces and thus does not have to be firmly connected to the piston or. As a result, minor misalignment of housing parts can be accepted and the production is facilitated.
- a main slide unit consisting of the main slide, a slide rod and a slide piston can also be constructed.
- an auxiliary slide unit consisting of the auxiliary slide and the pins can be constructed in the same way.
- a method of performing a cold vapor process comprises a step of controlling a mass flow of a fluid serving as a refrigerant, which is at an evaporator pressure level, by a motor-driven one
- Main compressor is compressed to high pressure level. This mass flow of the fluid, which is at high pressure level, is cooled in a high pressure heat exchanger, increasing density and lowering a temperature of the fluid. The coming of the high-pressure heat exchanger fluid is working in an expander
- the expander is mechanically connected directly to a high pressure compressor.
- the fluid coming from the expander is passed into an evaporator where it absorbs heat, so that the density of the fluid decreases and the temperature of the mass flow of the fluid coming from the expander, which increases
- Evaporator pressure level is increasing.
- the fluid is passed through a subcooler, wherein between the subcooler and before the expander, a portion of the fluid from the high pressure level mass flow is diverted and expanded by means of a high pressure control valve to medium pressure level.
- the fluid is passed in countercurrent to the passed through the subcooler mass flow, which is at high pressure level, at medium pressure level through the subcooler, wherein it absorbs heat and the mass flow, which is at high pressure level, is undercooled.
- the fluid passes in the branched
- the fluid is led to the expander in a collector, in which a liquid phase of the fluid is separated from a vapor phase of the fluid.
- the liquid phase is expanded to evaporator pressure via an injection valve.
- the vapor phase of the fluid is released via a pressure-holding valve and admixed downstream of the evaporator into the mass flow of the fluid coming from the evaporator.
- a fluid which is also referred to as a refrigerant in this context, carbon dioxide, C0 2 , can be used because carbon dioxide is not explosive and non-combustible, but thermally stable.
- a refrigerant its advantages include a low specific volume and a high heat transfer coefficient and low pressure losses in a flow through heat exchangers.
- the described method can be carried out with the described device or the described device is set up to carry out the described method.

- a low pressure circuit is shown, in which coming from a collector S through an injection valve TV, a fluid, in the illustrated embodiment, carbon dioxide, passes through an evaporator V to a motor-driven main compressor Cl.
- the fluid compressed by the main compressor Cl mixes with a medium-pressure mass flow of the fluid compressed by a high-pressure compressor C2 in front of the high-pressure heat exchanger H, in which a higher pressure than in the collector S is maintained. From the high pressure heat exchanger H, the fluid passes through a subcooler U and the expander E back into the collector S.
- a separate medium-pressure mass flow is compressed by the high-pressure compressor C2 driven directly by the expander E before it enters the high-pressure heat exchanger H.
- the high-pressure compressor C2 compresses only this medium-pressure mass flow, so no fluid that is out of the medium-pressure mass flow.
- the high-pressure heat exchanger H which is also referred to as a gas cooler or condenser
- the fluid flowing straight from the high-pressure heat exchanger H and into a subcooler U lying between the high-pressure heat exchanger H and the expander E is divided after passing through the subcooler U. A smaller part, typically between
- a throttle TH also referred to as a high pressure regulator.
- the branched fluid in the subcooler U in countercurrent heat and reaches the high pressure compressor C2.
- the high-pressure mass flow of the fluid is additionally undercooled.
- the exergy of the expansion is thus an additional undercooling at high pressure.
- the medium pressure mass flow compressed by the high pressure compressor C2 back to high pressure before the high pressure heat exchanger H is added to the fluid coming from the main compressor C1.
- a pressure difference and a suction volume flow can be set freely on the high-pressure compressor C2 in accordance with an offer on the expander side. If the high-pressure control valve or throttle TH is closed, its pressure difference increases until the sketched expander compressor unit stops and no expander mass flow is no longer present. The result is an increasing high pressure. If the high-pressure control valve TH now slowly opened, the medium pressure increases again, until the expander E is running and the desired expander mass flow, high pressure and
- the collector pressure in the collector S is selected to be sufficiently high to ensure sufficient controllability of the injection valve TV and of a pressure-maintaining valve TS arranged in a line connected between a vapor space of the collector S and downstream of the evaporator V collector and upstream of the main compressor C1.
- Evaporator pressure allows a constant low collector pressure, regardless of the high pressure.
- a coefficient of performance at -10 ° C. evaporation temperature and 20 ° C. ambient temperature can be reduced by approx. 15 percent compared to a simple cold steam process in which only a compressor, a high-pressure gas cooler or condenser, a throttle valve, a collector and an evaporator are used in a known manner, be increased.
- the high pressure remains at comparable values. To get an even bigger boost, there can be more

- FIG. 2 shows, in a view corresponding to FIG. 1, the described process control without the collector S. Recurring features are provided with identical reference symbols in this figure as well as in the following figures.
- the expander E thus directs the fluid directly to the evaporator V, without the fluid previously passing through the collector S. Accordingly, that too
- Figure 3 shows a side view of a cross section through an expander compressor unit from the expander E and the high pressure compressor C2, which are arranged in a common housing 10 and thus the
