Description
CLIMATE CONTROL UNIT AND SYSTEM COMPRISING THE SAME The present invention concerns an assembly for constructing a climate control unit. The invention also concerns a climate control unit constructed from such an assembly. The invention furthermore concerns a system comprising such a climate control unit and a condenser.
Climate control systems are known from the art and generally comprise a compressor, a condenser and an evaporator. The compressor, as the active element, provides pressurized and heated gaseous refrigerant to the condenser. In the condenser, the refrigerant condenses. The energy that is associated with the condensation process is released to an outside of the condenser, e.g. the ambient air. The cooled off liquid refrigerant is then fed to the evaporator. Prior to entering the evaporator, the pressure of the refrigerant is lowered using an expansion valve thereby reducing the boiling point of the refrigerant. This allows the refrigerant to evaporate inside the evaporator. Thermal energy required for the evaporation process is extracted from the air around the {5 evaporator. After leaving the evaporator, the heated gaseous refrigerant is again fed to the compressor and the process can be repeated.
In a typical climate control system, the evaporator and compressor are arranged as a single unit that is mounted to a wall or ceiling of the room to be cooled. Such unit will hereinafter be referred to as a climate control unit. Because of the function that this unit performs, it is also sometimes referred to as a heat pump.
A particular type of climate control unit is that of the packaged type. These units are commonly used in places like grow-rooms, hotels, restaurants, homes, and halls.
In such units, all important components of the climate control unit are included in a single housing, and this one unit is assembled at a manufacturing location. Further components included in the unit are for example a heat exchanger which acts as the condenser, a fan, and/or air filter. Additionally, to be able to endure the relatively high capacities of these components, housing of such packaged type climate control units is usually substantially made of metal.
When the climate control system is configured to cool large rooms or spaces, the weight of the required evaporator and/or compressor will increase thereby complicating the mounting and transport of the climate control unit.
It is an object to provide a climate control unit which can be transported and assembled, in particularly in hard to reach places, more easily.
The invention solves said problem as it provides an assembly for constructing a climate control unit, wherein the assembly comprises a first housing section having a first outer wall, and a compressor arranged in the first housing section. The assembly further comprises a second housing section having a second outer wall, and an evaporator arranged in the second housing section. The second housing section is detached or detachable from the first housing section.
The evaporator comprises an outlet to which a first connector is connected that extends in a first connector space. The compressor comprises an inlet to which a second connector is connected that extends in a second connector space, wherein the first and second connectors are configured to be coupled to each other for allowing refrigerant to pass from the evaporator to the compressor.
The first and second housing sections are each configured to be individually and separately mounted to a supporting structure, wherein the first and second housing sections are configured to be adjacently arranged when mounted to the supporting structure such that the first and second connector spaces adjoin or at least partially overlap for forming an adjoined connector space and such that the first and second outer walls cooperate to form an outer wall of the climate control unit. Moreover, the adjoined connector space is completely contained in a volame defined by the outer wall of the climate control unit.
At least one of the first and second outer walls comprises an opening allowing access to the adjoined connector space for the purpose of connecting the first and second connectors to each other.
The assembly of the invention allows the user to arrange the respective first and second housing sections in their desired locations individually, significantly reducing the amount of weight that has to be moved at a time. The opening provided in the first and/or second outer wall resolves the problem that presents itself when the first and second housing sections are adjacently arranged, as it ensures that the first and second connectors can still be accessed even through the first and second outer walls are combined to form the outer wall of the climate control unit.
More in particular, the first connector can be configured to extend from the outlet of the evaporator towards the first housing section when the first and second housing sections are mounted to the supporting structure in an adjacent manner. Similarly, the second connector can be configured to extend from the inlet of the compressor towards the second housing section when the first and second housing sections are mounted to the supporting structure in an adjacent manner.
The assembly may comprise a cover plate for closing off the opening after having connected the first and second connectors to each other. The cover plate ensures that the adjoined connector space cannot easily be accessed during use. The cover plate, when it closes off the opening, may lie in plane with the outer wall of the climate control unit to provide a smooth outer appearance of the outer wall of the climate control unit.
The first housing section may comprise a first wall segment and the second housing section may comprise a second wall segment. The first housing section could further comprise a third wall segment that is arranged inwardly relative to the first wall segment, and the second housing section could further comprise a fourth wall segment that is arranged inwardly relative to the second wall segment. In such case, the second connector could extend through an opening in the third wall segment and the first connector could extend through an opening in the fourth wall segment. When the first and second housing sections are adjacently arranged, the third and fourth wall segments may at least partially define the adjoined connector space, and the first and second wall segments may face each other. The first to fourth wall segments cover an inside of the respective housing sections when these are not yet installed, thereby protecting the respective inside components.
An inverter for controlling the compressor, as well as a cooling element for cooling the inverter may be included in the assembly. The cooling element may protrude through an opening in the first wall segment. Furthermore, when the first and second housing sections are adjacently arranged, the cooling element may protrude through an opening in the second wall segment.
The first and second housing sections may each essentially be box or beam shaped, having six sides, wherein the first outer wall is associated with five sides among the six sides of the first housing section, and wherein the first and third wall segments are associated with the remaining side of the first housing section, and wherein the second outer wall is associated with five sides among the six sides of the second housing section, and wherein the second and fourth wall segments are associated with the remaining side of the second housing section.
In addition to the above, the first housing section may comprise a first frame in or to which the first outer wall and the first and/or third wall segments are mounted. Additionally or alternatively, the second housing section may comprise a second frame in or to which the second outer wall and the second and/or fourth wall segments are mounted.
The compressor may comprise an outlet to which a third connector is connected and/or the evaporator may comprise an inlet to which a fourth connector is connected. The third connector can be configured to be connected to an inlet of a condenser and the fourth connector can be configured to be connected to an outlet of the condenser. The assembly may comprise a heat exchanger, arranged in the first housing section and comprising a first connector set comprising an inlet and an outlet and a second connector set comprising an inlet and an outlet, wherein the heat exchanger is configured to exchange heat between the refrigerant flowing from the inlet of the first connector set to the outlet of the first connector set and a second fluid flowing from the inlet of the second connector set to the outlet of the second connector set. In this case. the fourth connector may extend in the first connector space, and the assembly may further comprise a fifth connector extending in the second connector space, wherein the fourth and fifth connectors are configured to be coupled to each other. Furthermore, the third connector may be connected to the inlet of the first connector set and the fifth connector may be connected to the outlet of the first connector set. The assembly may further comprise a sixth and seventh connector, each extending through the first outer wall, wherein the sixth connector is connected to the inlet of the second connector set and the seventh connector to the outlet of the second connector set. Refrigerant passing from the inlet of the first connector set to the corresponding outlet will condense. Preferably, the second fluid comprises water that is pumped through the heat exchanger.
When the first and second housing sections are adjacently arranged, the first and second outer walls may be aligned. Any of the provided connectors may comprise threaded connections.
Said type of connectors can be connected by hand or by hand-held tools. For this reason, the opening only has to be big enough to fit either of these through.
The assembly may further comprise the supporting structure to which the first and second housing sections can be mounted.
According to a second aspect, the present invention provides a climate control unit, such as an air-conditioning unit, comprising the assembly as defined above, wherein the first and second housing sections are adjacently arranged and mounted to the support structure, and wherein the first and second connectors are coupled to each other, and wherein, in so far as they are both present, the fourth and the fifth connectors are coupled to each other.
According to a third aspect, the present invention provides a climate control system that comprises the abovementioned climate control unit and a pump for pumping the second liquid, wherein the sixth connector is connected to an outlet of the pump, and wherein the seventh connector is connected to an inlet of the pump.
Further advantages, features and details of possible embodiments of the present invention will be elucidated on the basis of the following description of the accompanying figures, wherein: Figure } shows a perspective view of a climate control unit according to the present invention; Figure 2 shows how the first and second housing sections of the climate control unit shown in figure 1 can be connected when said housing sections are arranged directly adjacent to each other; Figure 3 shows some of the inner components of the climate control unit shown in figure 1; Figure 4 shows an embodiment of a climate control unit, wherein the outer wall is omitted; Figure 5 shows an embodiment of a first housing section of a climate control unit according to the invention; and figure 6 shows a cross-section of an embodiment of a climate control unit.
In figure 1, a climate control unit according to the present invention is shown. As will be described, the climate control unit is assembled from an assembly according to the present invention.
In particular, a first housing section 1A and a second housing section 1B are shown, which are both arranged on a supporting structure formed by beams 20 that are suspended from a ceiling through cables and/or rods 21. In this configuration, housing sections JA and 1B of the assembly are arranged directly adjacent to each other,
Such an arrangement of the housing sections 1A and 1B also means that a climate control unit made of an assembly according to the invention can be installed in a system originally designed to house packaged type climate control unit. Alternatively, when installing new climate control systems, well known designs can still be used and do not have to be adapted for them to be 5 able to house a climate control unit according to the invention.
When installed, the first housing section 1A and second housing section 1B will take up space the same space as, and/or not look any different from a regular, one part packaged type climate control unit. Moreover, assemblies according to the invention are a lot easier to install in such systems as the housing sections 1A and 1B can be installed independently before they are IO connected.
First housing section 1A is provided with a first outer wall 4A through which a connector 13 and a connector 18 extend. Furthermore, in first outer wall 4A an opening 7 is provided which is covered by a cover plate 8. Second housing section 1B is provided with a second outer wall 4B. When arranged as shown in the figure, these respective outer walls completely cover the components arranged inside of the climate control unit when operational. Either one of the first or second housing section 1A. 1B can be arranged first.
How the internal elements of the respective housing sections can be connected to each other is shown in figure 2. This figure 2 illustrates that first and second housing sections 1A, 1B are detached from each other. These sections can be individually and separately mounted to a supporting structure, such as beams 20 shown in figures 1 and 3. First and second housing sections 1A, 1B are configured to be adjacently arranged when mounted to the supporting structure as illustrated in figares 1 and 3.
In first housing section 1A, which is shown in more detail in figure 5, connectors 15A and 15B are arranged in a second connector space 6. In second housing section 1B, connectors 14A and 14B are arranged in a first connector space 5. As is indicated by the arrows, once first and second housing sections 1A, 1B are arranged in their respective positions, connector 15A is close enough to connector [4A and connector 15B is close enough to connector 14B to be connected. These respective connections can be made in the adjoined connector space that is formed by the first and second connector spaces 5, 6 adjoining or at least partially overlapping. Connectors 14A, 14B, 15A, 15B can for example be complementary threaded connections that would allow a user to couple the connectors to each other by hand or by use of light tools.
To avoid the situation in which the respective connector spaces and connectors are inaccessible through the outer walls of the first and second housing sections 1A, 1B, an opening 7 is provided in outer wall 4A. This opening may also be provided in other walls as long as the opening provides access to the adjoined connector space. Cover plate 8 is shaped complementary to opening 7 and covers opening 7 completely when it is arranged in or on it. The skilled person can envision multiple manners in which cover plate 8 can be connected to housing section 1A such as through screws or clips.
First housing section 1A also comprises a wall segment 2 which covers the side of first housing section 1A that will face second housing section 1B, once installed. This is primarily to protect the components inside of first housing section 1A during transport and assembly. Similarly, second housing section 1B comprises a wall segment 3.
To make sure that the respective connector spaces will still form the adjoined connector space, wall segments 2 and 3 do not completely cover the sides of the housing sections 1A, 1B. Instead, a further wall segment 2A is provided which is arranged further inward in first housing IO section 1A. Wall segment 2B connects wall segments 2A and wall segment 2. Wall segments 2, 2A, in combination with outer wall 4A, delimit second connector space 6. As was also said in light of figure 1, second connector space 6 can be accessed through opening 7 even if first and second housing sections 1A, 1B are arranged directly against each other.
Similarly, second housing section 1B comprises a further wall segment 3A which delimits second connector space 5. Wall segment 3B connects wall segments 3B and wall segment 4. Wall segments 3, 3A, in combination with outer wall 4B, delimit first connector space 5. The connectors 14A, 14B extend through said wall section with a relatively short piece of conduit.
While it is possible that either connectors 14A, 14B or 15A, 15B extend further from their respective housing section to reach the connector on the other side in the other housing section, in this embodiment each of the connectors reaches up to or slightly beyond their respective housing sections. It is advantageous to have these connectors extend from their housing sections as little as possible since having them extend far will make them vulnerable during transport and installation.
From first housing section 1A, a cooling element 16 may protrude through wall section 2. A further opening 17 which can receive cooling element 16 is arranged in wall section 3.
As will be shown later, in the embodiment discussed in figures 1-3, a compressor 11 is arranged in first housing section 1A and an evaporator 12 is arranged in second housing section 1B. Furthermore, electronics to control the compressor, such as an inverter, can also be arranged in first housing section 1A. Cooling element 16, arranged to cool at least part of the electronics to control the compressor, can then directly make use of the cooling power of the climate control unit through cooled air flowing inside second housing section 1B.
Figure 3 shows some of the inner components of the climate control unit of figure 1. In this figure, some elements of outer walls 4A, 4B of the respective housing sections 1A, 1B are omitted. This makes clear that first and second housing sections 1A, 1B each consist of respective frame 22A, 22B to which outer walls 4A, 4B and wall segments 2, 2A, 2B, 3, 3A, 3B can be mounted.
Frames 22A, 22B equally facilitate the mounting of evaporator 12 and compressor 11 as well as other components of the climate control unit,
Again, the first and second housing sections 1A, 1B are arranged directly adjacent to each other, allowing the elements inside to be connected. More in particular, figure 3 shows that second housing section 1B comprises a wall element 32 of outer wall 4B that has an opening 31 through which air can be drawn into housing section 1B through a fan 33. Incoming air can be drawn in from the environment of the climate control unit directly or opening 31 can be connected to an additional air conduit system. Furthermore, second housing section 1B comprises a trellis 30 through which air cooled by evaporator 12 is output from the housing section, back into the surrounding environment. In an assembly according to the invention, condensation can be provided in a number of ways. It is for example possible to use an external condenser (not shown).
In another assembly according to the invention, condensation of the refrigerant is provided by a heat exchanger 10 arranged in first housing section 1A.
Figure 4 discloses such an embodiment. heat exchanger 10 comprises, to allow the refrigerant to flow through it, a first connector set comprising an inlet and an outlet, and for a second fluid, e.g. water, to flow through it, a second connector set comprising an inlet and an outlet. In this embodiment, the outlet of compressor 11 is connected to an inlet of the first connector set, and the outlet of the first connector set is connected to an inlet of evaporator 12 via connectors 14B, 15B. The outlet of evaporator 12 is connected via connectors 14A, 15A to an inlet of compressor 11. This configuration is shown in more detail in figure 6.
Second fluid, e.g. liquid water, can be fed to heat exchanger 10, using a pump that has an inlet connected to outlet of the second connector set and an outlet connected to inlet of the second connector set.
In this embodiment, during operation, compressor 11 will be fed using heated gaseous refrigerant that is superheated to above the boiling point. The compressed gaseous refrigerant will condense in heat exchanger 10. The liquid pressurized refrigerant will be fed via an expansion valve (not shown) to evaporator 12. There, refrigerant will evaporate under the adsorption of heat from the air that is sucked into second housing section 1B using fan 33. The evaporated refrigerant is then fed to the inlet of compressor 11 and the process can be repeated.
The skilled person will realize that the abovementioned embodiments are merely exemplary embodiments. Various modifications can be made to the assembly without departing from the scope of the invention which is defined by the appended claims.
