Description

State of the art

[0001] In the prior art, refrigeration machines are known to have a refrigeration circuit housing or an electronics housing. During operation of the refrigeration machine, the refrigeration circuit housing or the electronics housing can heat up.

[0002] Condensation drainage systems are commonly found in air-to-air refrigeration units, where humidity regularly condenses into water. Depending on operating and environmental conditions, this condensation can freeze within the drainage system.

[0003] The purpose of the invention is to provide an improved refrigeration machine. Disclosure of the invention

[0004] The invention relates to a refrigeration unit with a refrigeration circuit housing and / or an electronics housing as well as with a condensate drainage device.

[0005] It is proposed that the refrigeration circuit housing and / or electronics housing be designed, at least in sections, as a condensate drainage device.

[0006] This creates a condensate drainage device that is combined with a housing section of the refrigeration circuit housing and / or electronics housing in one component or assembly.

[0007] The condensate drainage system can be heated by the refrigeration circuit housing or electronics housing, which heats up during operation of the refrigeration unit. For this heating – especially passive heating – no additional auxiliary device such as a heater is required.

[0008] Cooling of the refrigeration circuit housing or electronics housing can be achieved via the surface of the housing section that forms the condensate drainage device. For cooling the electronics housing – especially passive cooling – no additional auxiliary device such as a fan is required.

[0009] In this context, "chiller unit" refers specifically to a heat pump, an air conditioning system, a ventilation unit, or a subsystem of these units, from which condensate must be regularly drained. "Housing" refers specifically to a rigid enclosure, for example, a box-shaped enclosure, which may be made of sheet metal. "Refrigerant circuit housing" refers specifically to a housing in whose interior important components of the chiller are arranged, connected by refrigerant lines to form a refrigerant circuit. The refrigeration circuit housing can serve to protect the refrigeration circuit components from unauthorized access or to prevent unintentional refrigerant leakage from the surrounding area.In this context, a refrigerant is understood to be, in particular, a working fluid, for example, a flammable working fluid, which can absorb heat in a refrigeration process at low temperature and low pressure and release heat at higher temperature and higher pressure. An "electronics housing" is understood to be, in particular, a housing in whose interior important components of the device's electronics are located. The electronics housing serves to protect the electronic components from unauthorized access, moisture, and other corrosive influences. In particular, the electronics housing shields the electronic components, as potential ignition sources, from contact with unintentionally escaping refrigerant and thus contributes significantly to operational safety.Just as the refrigeration circuit components and electronic components heat up during operation of the refrigeration unit, so too do the refrigeration circuit housing and / or the electronics housing. Here, a "condensate drainage device" is understood to mean, in particular, a device that serves to collect, gather, and drain the condensate that forms during operation of the refrigeration unit. The phrase "the refrigeration circuit housing and / or electronics housing being designed, at least partially, as a condensate drainage device" is understood to mean, in particular, that a section of the housing is designed as a condensate drainage device. Alternatively, it is understood to mean that the entire housing is designed as a condensate drainage device.A "housing section" designed as a condensate drainage device can, for example, be a flat and / or level and / or, in the operational configuration of the refrigeration unit, inclined housing section relative to a horizontal. For example, the main dimensions of such a housing section can be approximately the same as the main dimensions of the adjacent housing. Alternatively, the main dimensions of such a housing section can be larger than the main dimensions of the adjacent housing, i.e., projecting beyond the adjacent housing.

[0010] The term "operational setup of the refrigeration equipment" here refers in particular to an installation at the place of operation and / or in an orientation in the room as is intended for proper operation.

[0011] The terms "housing section inclined relative to a horizontal" and "condensate tray inclined relative to a horizontal" are used here to mean, in particular, that a base or bottom surface of the housing section or condensate tray, on which the condensate collects, has a slope angle G relative to the horizontal, wherein G is in a range between 0.5° and 5°, preferably in a range between 2° and 3°. The slope directs the collected condensate to a condensate drain opening.

[0012] Designing at least part of the refrigeration circuit housing and / or electronics housing as a condensate drainage device has many advantages.

[0013] Key advantages include the effective, especially passive, cooling of the housing and its components, as well as the effective, especially passive, heating of the condensate drainage device and the condensate contained therein.

[0014] Due to the box-shaped design of the housing and the flat shape of the condensate tray, the design and manufacture of the unit consisting of the housing or housing section and the condensate drainage device is simple.

[0015] Due to the smooth and / or flat bottom surface of the condensate tray, the condensate drains easily into a condensate drain opening, and the condensate tray is easy to clean.

[0016] In a preferred embodiment, an upper housing section, in particular a housing cover, of the refrigeration circuit housing and / or the electronics housing is designed as a condensate drainage device.

[0017] For example, in the operational configuration of the refrigeration unit, the refrigeration circuit housing and / or electronics housing is located below the condensate drainage device. In this way, the condensate drainage device protects the refrigeration circuit housing and / or electronics housing, as well as the components located within it, from condensate dripping from above.

[0018] The upper housing section of the refrigeration circuit housing can be permanently connected to the housing. The housing cover of the refrigeration circuit housing can be removable, thus allowing access to the interior of the housing, for example, for maintenance purposes. Preferably, the upper housing section or the housing cover, on the one hand, and the refrigeration circuit housing, on the other hand, are thermally connected or connectable to each other.

[0019] In a further preferred embodiment, the housing section of the refrigeration circuit housing and / or electronics housing designed as a condensate drainage device includes a trough-like area forming a condensate tray.

[0020] The trough-like area is particularly suitable for collecting and catching condensate dripping from above. The trough-like area has a contour that is essentially flat and / or level and / or inclined relative to the horizontal when the refrigeration unit is in its operational position. In particular, the main dimensions (width, length) of the trough-like area are identical or essentially identical to the main dimensions (width, length) of the housing section designed as a condensate drainage device. A surrounding wall around the edge of the trough-like area ensures that the condensate does not overflow.

[0021] In a further preferred embodiment, the housing section of the refrigeration circuit housing and / or the electronics housing, designed as a condensate drainage device, includes a recess forming a condensate drain opening.

[0022] The condensate drain opening is particularly suitable for draining the collected condensate from the condensate tray. The drain opening is located on the surface of the condensate tray, specifically in a central or peripheral area. When the refrigeration unit is in its operational position, the condensate tray's inclined surface relative to the horizontal ensures that the collected condensate flows along the incline towards the drain opening.

[0023] In a further preferred embodiment, a condensate drain line is connected to the condensate drain opening. Alternatively, a condensate drain line can be connected to the condensate drain opening. The condensate drain opening opens, in particular in a fluid-tight manner, into the condensate drain line. The condensate drain line runs, in particular in a fluid-tight manner, through the interior of the housing and exits the refrigeration circuit housing and / or electronics housing at a further housing section, in particular a housing base. The condensate drain line can be designed as part of the condensate drainage device.

[0024] The condensate drain line leads in particular to a drainage device for discharging the condensate, for example into a sewage system or a drainage pit.

[0025] Because the condensate drain line, which is particularly fluid-tight, runs through the interior of the housing, the drain line and the condensate flowing into it are warmed from within the housing. This ensures that the condensate in the drain line does not freeze and drains away reliably.

[0026] In a further preferred embodiment, at least one heat-generating and / or heat-emitting component is arranged in the refrigeration circuit housing, particularly during operation of the refrigeration unit, wherein the heat-generating and / or heat-emitting component is in particular selected from a group comprising a refrigerant compressor, a refrigerant receiver, a refrigerant line, and a heat exchanger.

[0027] Alternatively or additionally, in a further preferred embodiment, at least one heat-generating and / or heat-emitting component, particularly during operation of the refrigeration unit, is arranged in the electronics housing, wherein the heat-generating and / or heat-emitting component is in particular selected from a group comprising a heat exchanger, power electronics, an electrical converter, an electrical inverter, an electrical filter, a control unit, a regulating unit, and a printed circuit board.

[0028] In this context, a heat-generating component is understood to be a component or part that, particularly during the operation of the refrigeration unit, generates heat output, especially waste heat output. This heat output, especially waste heat output, arises, for example, from mechanical friction, current flow through electrical resistance, or an exothermic reaction.

[0029] In this context, a heat-emitting component is understood to be a component or part that emits heat, particularly waste heat, during the operation of the refrigeration unit. This heat, especially waste heat, arises, for example, from a temperature difference between the component and its surroundings. These surroundings may include, for example, the refrigeration circuit housing and / or electronics housing, a housing wall, and / or the condensate drainage system.

[0030] During operation of the refrigeration unit, the refrigeration circuit components heat the refrigeration circuit housing and / or its interior and / or its housing walls. During operation of the refrigeration unit, the electronic components heat the electronics housing and / or its interior and / or its housing walls.

[0031] In a further preferred embodiment, the refrigeration circuit housing and / or electronics housing comprises at least one first thermal insulation element, wherein the first thermal insulation element insulates at least one further outer wall section of the heating refrigeration circuit housing and / or electronics housing against heat loss. The housing section designed as a condensate drainage device remains uninsulated or less insulated.

[0032] The term "further outer wall section" of the housing is here understood to mean in particular a further housing section that separates the housing or the housing interior from an environment, but is not identical with the housing section designed as a condensation drainage device.

[0033] The heat loss thus advantageously occurs mainly at the condensate drainage device, so that the condensate drainage device is heated by means of the heat loss.

[0034] In a further preferred embodiment, the refrigeration circuit housing and / or electronics housing comprises at least a second thermal insulation element, wherein the second thermal insulation element insulates cold components against heat absorption during operation. In this configuration, heat-generating and / or heat-emitting components remain at least partially uninsulated or less well insulated.

[0035] The term "components that remain cold during operation" refers in particular to components that do not generate and / or emit heat during operation, but rather absorb and / or dissipate heat from the housing.

[0036] The term "uninsulated" here refers specifically to the fact that no thermal insulation element is installed on the condensate drainage device or heat-generating / heat-emitting component. The term "less well insulated" here refers specifically to the fact that any thermal insulation element present on the condensate drainage device or heat-generating / heat-emitting component is not a primary or secondary thermal insulation element and has a lower thermal insulation value than the primary or secondary thermal insulation element.

[0037] In a further preferred embodiment, the housing wall and / or the housing section designed as a condensation drainage device has surface area-enlarging and / or stiffening elements such as ribs or knobs.

[0038] Surface-enlarging and / or stiffening elements are understood here to mean, in particular, elements arranged on the side of the housing wall facing the interior of the housing, especially on the side of the condensate drainage device facing the interior of the housing. These elements can act as heat-conducting elements, resulting in improved heat absorption from the housing into the condensate drainage device.

[0039] Alternatively or additionally, the term "surface-enlarging and / or stiffening elements" shall be understood here to mean, in particular, elements arranged on the side of the housing wall facing away from the housing interior, especially on the side of the condensate drainage device facing away from the housing interior. These elements can act as heat-conducting elements, resulting in improved heat transfer from the condensate drainage device into the condensate.

[0040] The surface-enlarging and / or stiffening elements can be formed as a single component and / or made of the same material and / or monolithically with the condensate drainage system. Alternatively, the elements can also be joined to the condensate drainage system, for example, by screwing, riveting, soldering, welding, or bonding. It is particularly important that a thermally conductive connection is created between the elements and the condensate drainage system.

[0041] The aforementioned elements can stiffen the housing wall, in particular the condensate drainage device, and thus make it more robust against, for example, a load from condensate and / or condensate ice.

[0042] In a further preferred embodiment, at least one heat-generating and / or heat-emitting component is arranged on the housing section designed as a condensate drainage device and / or connected to it, in particular by means of at least one heat-conducting structure.

[0043] The term "connected" here refers specifically to a direct or indirect, permanent or detachable connection. A direct, detachable connection can be created by contact pressure or screwing. A permanent connection can be created by soldering. A thermally conductive structure, in particular a thermal paste, a thermal pad, or a heat pipe, can be understood as an indirect connection that facilitates thermally conductive contact between the heat-generating and / or heat-emitting component on the one hand and the condensate drainage device, in particular the condensate tray, on the other.

[0044] The aforementioned heat-generating and / or heat-emitting component shall be understood to mean, for example, a converter, an inverter, a refrigerant line and / or a heat pipe that is arranged on the condensate drainage device.

[0045] The condensate drainage device is thus heated directly by the heat-generating and / or heat-emitting component. In other words, the heat-generating and / or heat-emitting component is cooled directly by the condensate drainage device.

[0046] Another preferred embodiment includes a heat exchanger associated with the condensate drainage device, in particular an air / refrigerant heat exchanger.

[0047] This heat exchanger is specifically designed to remove moisture, such as condensate. In this context, an air / refrigerant heat exchanger refers specifically to a heat exchanger that functions as a refrigerant evaporator during the heating operation of the refrigeration unit, and on which atmospheric moisture can condense into water. The condensate drainage system is located below the heat exchanger in the refrigeration unit's operational configuration, allowing the moisture to drip into the drainage system.

[0048] Heat is released from the condensate drainage device into the collected moisture and / or into the environment of the heat exchanger, for example into an airflow passing through the air / refrigerant heat exchanger.

[0049] In a further preferred embodiment, the condensate drainage device has an unobstructed visual connection and / or a heat conduction connection to the heat exchanger.

[0050] In this context, "direct contact" refers specifically to the fact that the warm condensate drainage device allows direct heat radiation onto the heat exchanger. The heat exchanger can thus warm up due to this radiation and use this heat to evaporate a working fluid, particularly a refrigerant flow, passing through the heat exchanger. drawing

[0051] Further embodiments and advantages will become apparent from the following description of the drawings. The drawings illustrate exemplary embodiments of the invention. The drawings, the description, and the claims contain numerous features in combination. It is advantageous for those skilled in the art to also consider the features individually and combine them into meaningful further combinations. The drawings schematically show: Fig. 1 a longitudinal section through a refrigeration unit designed as an outdoor unit of a heat pump, Fig. 2 a perspective view of a refrigeration circuit housing with a condensate drainage device, Fig. 3 a perspective view of a refrigeration circuit housing with an air / refrigerant heat exchanger, Fig. 4 A perspective view of an electronics enclosure with an air / refrigerant heat exchanger, Fig. 5 a longitudinal section through an electronics housing with an air / refrigerant heat exchanger.

[0052] Fig. Figure 1 shows a longitudinal section through a refrigeration unit 100 designed as an outdoor unit of a heat pump.

[0053] The in Fig. The refrigeration unit 100 shown is an air-to-water refrigeration unit, for example an air / water heat pump, which transfers heat between an airflow L conveyed by a fan 116 and a refrigerant flow conveyed by a refrigerant compressor (not shown) by means of an air / refrigerant heat exchanger 112. The refrigerant flow circulates in a refrigerant circuit (not shown).

[0054] The refrigeration unit 100 comprises a refrigeration circuit housing 102 and / or electronics housing 104 and a condensate drainage device 200. The refrigeration circuit housing 102 and / or electronics housing 104 heats up, particularly during operation of the refrigeration unit 100. The condensate drainage device 200 serves to collect and drain condensate K that forms, for example, on the heat exchanger 112 from the airflow L, particularly during operation.

[0055] The refrigeration circuit housing 102 and / or electronics housing 104 is designed, at least in sections, as a condensate drainage device 200. Fig. 1 is an upper housing section, in particular a removable housing cover, of the refrigeration circuit housing 102 and / or the electronics housing 104 in the operational configuration of the refrigeration unit 100, designed as a condensate drainage device 200. The actual housing 102, 104 or a housing interior defined by the housing 102, 104 is arranged below the condensate drainage device 200.

[0056] The refrigeration circuit housing 102 and / or electronics housing 104, which heats up during operation, or the refrigeration circuit components and / or electronic components in the housing 102, 104, which heat up during operation, ensure by means of their waste heat that the condensate K in the condensate drainage device 200 does not freeze, but remains liquid and can drain away safely.

[0057] The condensate drainage device 200 ensures that the condensate K does not penetrate the refrigeration circuit housing 102 and / or electronics housing 104 or the interior of the housing, but is instead conveyed through the refrigeration circuit housing 102 and / or electronics housing 104 via the condensate drain line 206. The refrigeration circuit components and / or electronic components located inside the housing are thus protected from the condensate K.

[0058] The refrigeration circuit housing 102 and / or electronics housing 104, which heats up during operation, ensures, by means of its outer wall, in particular by means of its housing section designed as a condensate drainage device 200, that the refrigeration circuit components and / or electronic components which heat up during operation release their waste heat and are effectively cooled.

[0059] The condensate drainage device 200 comprises a trough-like area forming a condensate tray 202 and a recess forming a condensate drain opening 204.

[0060] The base area or floor area 202a of the condensate tray 202 is - as shown on the right side of the Fig. Detail X, shown in isolation, is located in the operational configuration of the refrigeration unit 100, inclined at an angle G to a horizontal H, such that the condensate K, which collects in the condensate tray 202, flows along this slope to a low point in the condensate tray 202. The condensate drain opening 204 is advantageously located at this low point in the condensate tray 202; the condensate K can drain from the condensate tray 202 through the condensate drain opening 204.

[0061] A condensate drain line 206 connects to the condensate drain opening 204, with the condensate drain opening 204 opening into the condensate drain line 206. The condensate drain line 206 runs through the interior of the housing 102, 104, which heats up during operation, and exits the refrigeration circuit housing 102 and / or electronics housing 104 at a further housing section, in particular a housing base. The condensate drain line 206 opens into a drainage device A, for example a drain or a pit, where the condensate K leaves the refrigeration unit 100.

[0062] Fig. Figure 2 shows a perspective view of a box-shaped refrigeration circuit housing 102 with a condensate drainage device 200. A cutout drawn at the front corner provides a view into the refrigeration circuit housing.

[0063] The refrigeration circuit housing 102 has an upper housing section in the operational setup of the refrigeration unit 100, which is designed as a condensate drainage device 200.

[0064] An access opening (for example for maintenance purposes) into the refrigeration circuit housing 102 of the Fig. 2 is formed on a further outer wall section and is closed by means of a removable cover 114.

[0065] The condensate drainage device 200 has a trough-like area forming a condensate tray 202. The condensate tray 202 has a flat bottom surface 202a and is enclosed by a wall 202b running around its outer circumference, so that the condensate K does not overflow the edge. Furthermore, the condensate drainage device 200 has a condensate drain opening 204, which leads into a condensate drain line 206. The condensate drain line 206 runs fluid-tight through the interior of the housing, exits the refrigeration circuit housing 102 at a housing base, and discharges the condensate K into a drain device A (not shown here).

[0066] The refrigeration circuit housing 102 contains at least one refrigeration circuit component that generates and / or releases heat during operation of the refrigeration unit 100. This can be, for example, a refrigerant compressor, a refrigerant receiver, and / or a heat exchanger, and is located in Fig. 2 a refrigerant line 106.

[0067] The refrigeration circuit housing 102 includes at least one first thermal insulation element 110. The first thermal insulation element 110 insulates at least one further outer wall section of the heating refrigeration circuit housing 102 against heat loss to the environment. The housing section designed as a condensate drainage device 200 remains uninsulated or less well insulated. The further thermally insulated outer wall section of the housing 102 is distinct from the uninsulated or less well insulated condensate drainage device 200. The condensate drain line 206 is routed at least partially within the thermally insulated refrigeration circuit housing 102. Thus, the condensate tray 202 and the condensate drain line 206 heat up, and the condensate K contained therein cannot freeze.

[0068] In the refrigeration circuit housing 102 after Fig. 2 is a heat-generating and / or heat-emitting component, here a meandering refrigerant line 106, arranged on the condensate drainage device 200 and thermally connected to it. This connection can be established by direct contact or by means of at least one thermally conductive structure. In this way, the condensate drainage device 200 is heated and the condensate K cannot freeze within it. Fig. 2 the heat-generating and / or heat-emitting component is arranged at least sectionally on the side of the condensate drainage device 200 facing the interior of the housing.

[0069] Fig. Figure 3 shows a perspective view of a refrigeration circuit housing 102 with an air / refrigerant heat exchanger 112. A cutout drawn at the front corner provides a view into the refrigeration circuit housing.

[0070] The refrigeration circuit housing 102, which is designed section by section as a condensate drainage device 200, heats up during operation.

[0071] At least one initial thermal insulation element 110 insulates at least one further outer wall section of the heating refrigeration circuit housing 102 against heat loss. The housing section designed as a condensate drainage device 200 remains uninsulated or less well insulated.

[0072] The in Fig. A heat exchanger 112 is associated with the condensate drainage device 200 shown in Figure 3. This is, for example, an air / refrigerant heat exchanger 112, in particular an air chiller unit such as an air / water heat pump. Such an air / refrigerant heat exchanger 112 is filled with refrigerant and surrounded by air L to transfer heat between the refrigerant and the air L. It can, for example, be a refrigerant evaporator and / or a refrigerant condenser.

[0073] The condensate drainage device 200 is designed and arranged to collect, gather, and drain condensate K that forms and drips from the heat exchanger 112. In the operational configuration of the refrigeration unit 100, the condensate drainage device 200 is positioned below the heat exchanger 112, ensuring that condensate K dripping by gravity is reliably collected.

[0074] Since the condensate drainage device 200 heats up under the influence of the refrigeration circuit components which heat up during operation, the condensate K in the condensate drainage device 200 cannot freeze, but can safely drain away.

[0075] The heat transfer from the refrigeration circuit components and the refrigeration circuit housing 102 is to the condensate drainage device 200, to the condensate K and to the airflow L that flows around the heat exchanger 112.

[0076] The condensate drainage device 200 has an unobstructed (unobstructed) line of sight to the heat exchanger 112, so that heat radiation can also be transferred between the condensate drainage device 200 and the heat exchanger 112.

[0077] Fig. Figure 4 shows a perspective view of an electronics housing 104 with an air / refrigerant heat exchanger 112. A cutout drawn at the front corner provides a view into the electronics housing. Fig. Figure 5 shows a longitudinal section through the electronics housing 104 of Fig. 4.

[0078] The electronics housing 104 of a refrigeration unit 100 is partially designed as a condensate drainage device 200. Specifically, an upper housing section in the operational configuration, in particular a removable housing cover, of the electronics housing 104 is designed as a condensate drainage device 200.

[0079] A heat exchanger 112, for example an air / refrigerant heat exchanger 112, is associated with the condensate drainage device 200. The electronics housing 104, and with it the condensate drainage device 200, is arranged in its operational state below the heat exchanger 112, so that condensing humidity (condensate K) on the heat exchanger 112 can drip into the condensate drainage device 200 and collect there.

[0080] The condensate drainage device 200 comprises a condensate tray 202, a condensate drain opening 204, and a condensate drain line 206 connected to the condensate drain opening 204. The condensate drain line 206 runs fluid-tight through the interior of the housing so that no condensate K enters the interior of the housing and exits the electronic housing 104 at a housing base, in order to then flow into a drain device A.

[0081] The housing section designed as a condensate drainage device 200 has surface-enlarging and / or stiffening elements 208 on the condensate tray 202. These elements 208 constitute Fig. 4 heat-conducting fins; they can be located on the inside of the condensate tray 202 facing the interior of the housing and / or - as shown in Fig. 4 shown - to be attached on the outside facing the environment.

[0082] Furthermore, the ribs 208 can also serve to mechanically stiffen the condensate tray 202.

[0083] The electronic housing 104 contains at least one electronic component that generates and / or dissipates heat during operation. Examples include a heat exchanger, power electronics, an electrical inverter, an electrical filter, a control unit, a regulating unit, or a printed circuit board. Fig. 4 and Fig.5 an electrical converter 108.

[0084] At least one heat-generating and / or heat-emitting component, for example a converter 108 or an inverter, is arranged on the condensate drainage device 200, in particular on the inner side of the condensate tray 202 facing the interior of the housing, and is thermally connected to it by direct contact or by means of at least one thermally conductive structure. This ensures heat transfer from the heat-generating and / or heat-emitting component into the condensate drainage device 200.

[0085] The exemplary converter 108 or inverter has a contact surface that is in direct or indirect thermal contact with the side of the condensate tray 202 facing the interior of the housing. This allows waste heat to be transferred from the converter 108 or inverter to the condensate tray 202.
