Description

  The present disclosure relates to a temperature adjustment system and a control method thereof. More specifically, the present disclosure relates to a temperature regulation system that includes at least two temperature regulators and at least two flow controllers. The flow controller can be in different positions such that one temperature regulator can be in parallel and / or in series with one or more other temperature regulators.

  A temperature regulator can be used to heat or cool the working fluid. The working fluid may be water or a refrigerant, for example. Multiple temperature regulators can be used simultaneously to achieve the desired cooling or heating capability.

  The present disclosure relates to a temperature adjustment system and a control method thereof. More specifically, the present disclosure relates to a temperature regulation system that includes at least two temperature regulators and at least two flow controllers. The flow controller can be in different positions such that one temperature regulator can be in parallel and / or in series with one or more other temperature regulators.

  The “position” of the flow controller is defined to open and / or close a particular fluid flow within the temperature regulation system. For example, when the flow control device is a two-way valve, the flow control device can be in a closed position to stop fluid flow or an open position to allow fluid flow. In another example, when the flow control device is a three-way valve having input and output ports A, B and C, the flow control device stops the fluid flow at A and allows the fluid flow between B and C. Or a position that stops fluid flow at B and allows fluid flow between A and C.

  “Flow” is defined as the way in which the working fluid in the temperature regulation system flows in, for example, parallel flow, series flow, and / or combinations thereof. For example, the working fluid may flow in parallel flow in two or more temperature regulators. In another example, the working fluid may flow in series in two or more temperature regulators.

  “Connection” means a physical structural connection of the components in the temperature regulation system. The particular connection of the temperature regulation system may allow various fluid flows, for example parallel and / or series flow, as the flow control device can change the connection position.

  The present disclosure provides various embodiments of a temperature regulation system and control method thereof, and the position of the flow control device in the temperature regulation system can be such that the temperature regulator in the temperature regulation system can be in series and / or parallel flow. Can be changed as follows. The present disclosure provides various embodiments of a temperature regulation system with the freedom to change the fluid flow between parallel flow, series flow, or combinations thereof.

  To illustrate the advantages of flexibility according to embodiments of the present disclosure, consider the following example. One temperature regulation system does not have the freedom to change the fluid flow from parallel flow to serial flow. The temperature regulation system has two modular water coolers in parallel flow, for example two modular temperature regulators that use water as the working fluid. Modular water coolers are water coolers that can be added or removed from the system to increase or decrease the cooling capacity of the system, depending on the design and need of the system. In one situation, the water flow rate is less than its maximum flow capacity, for example 50% of its maximum flow rate. In this situation, for example, only one of the two temperature regulators can be activated and at the same time the other unit can be shut off. The reason is that if both parallel flow temperature regulators are operated simultaneously at 50% fluid flow rate, the temperature regulator unit can be damaged due to insufficient fluid flow rate. If only one of the two temperature regulators is used, 50% of the cooling capacity of the system may not be used because the other regulator is not working. However, if the temperature regulation system of this example has the freedom to change the fluid flow and change the two temperature regulators in parallel flow to series flow, the cooling capacity of both temperature regulators can be used simultaneously. The possibility of damage to the temperature regulator due to insufficient fluid flow may be avoided.

  The present disclosure provides various temperature regulation systems and methods for controlling the same that provide the ability to change the fluid flow, eg, series and / or parallel flow, of the temperature regulator. In other words, according to one embodiment, a temperature regulation system in a particular connection state may have parallel flow and / or series flow compatibility. Such compatibility can be achieved by controlling the position of the flow control device. For example, at one flow controller position, the temperature regulator can be in parallel flow. In another flow controller position, the temperature regulator may be in series flow. At different flow controller positions, the temperature regulators can be divided into sets, with the sets being in parallel flow between the sets and the regulators being in series within each set.

  In one embodiment, by way of example, a temperature regulation system includes two temperature regulators and two flow controllers with certain connections. In the connected state, for example, when the fluid flow rate is 100%, the flow rate control device can be positioned such that the two temperature regulators are in parallel flow. With the same connection, for example, when the fluid flow rate is 50%, the flow control device can be positioned such that the two temperature regulators are in series.

  In another embodiment, by way of example, a temperature regulation system includes three temperature regulators and four flow controllers with a particular connection. In the connected state, for example, when the fluid flow rate is 100%, the flow rate control device can be positioned such that the three temperature regulators are in parallel flow. With the same connection, for example, when the working fluid flow rate is 33%, the flow control device can be positioned such that the three temperature regulators are in series flow.

  In another embodiment, by way of example, a temperature regulation system includes four temperature regulators and six flow controllers with a particular connection. In a connected state, for example, when the fluid flow rate is 100%, the flow rate control device can be positioned such that the four temperature regulators are in parallel flow. In the same connection state, for example, when the working fluid flow rate is 50%, the flow control device is positioned such that the four temperature regulators are divided into two groups, group 1 and group 2, and group 1 and group 2 Can each include two temperature regulators. Set 1 is in parallel with set 2. Furthermore, within each set, two temperature regulators are in series. With the same connection, for example, when the working fluid flow rate is 25%, the flow control device can be in a position where all four temperature regulators are in series flow.

  A “temperature regulator” can include at least one cooling device, at least one heating device, or a combination thereof. A cooling device should be understood as any device capable of removing heat from a working fluid such as water, oil, refrigerant, etc. by heat exchange. In one embodiment, the cooling device is a cooler. In another embodiment, the cooling device is a water cooler. In yet another embodiment, the cooling device is a modular water cooler. A heating device should be understood as any device capable of applying heat to a working fluid such as water, oil, refrigerant, etc. by heat exchange. In one embodiment, the heating device is a water heater. In another embodiment, the heating device is a modular water heater.

  In one embodiment, the temperature regulation system may be used in radiant ceiling cooling using, for example, water as the main working fluid. In another embodiment, the temperature regulation system may be used with radiant floor heating using, for example, water as the main working fluid. In one embodiment, the temperature regulation system may be used in buildings and enclosed spaces and / or rooms, such as hotels, hospitals, schools, apartment houses, shopping malls, conference halls, houses, stadiums, and the like.

N, where N is any positive integer greater than or equal to 2. The fluid circuit further includes a total number (2N-2) of flow control devices, one fluid input, and one fluid output.

  For example, in one embodiment, the temperature regulation system includes a fluid circuit that includes fluidly connected components. The fluid circuit includes a first temperature regulator, a second temperature regulator, a first flow controller, a second flow controller, a fluid input, and a fluid output. Within the fluid circuit, the fluid input is located upstream of the first temperature regulator and upstream of the second flow controller. The fluid output is disposed downstream of the first flow controller and downstream of the second temperature regulator.

A first flow control device is disposed downstream of the first temperature regulator and upstream of the fluid output. A second flow control device is disposed downstream of the fluid input, downstream of the first temperature regulator and upstream of the second temperature regulator.

  A “flow control device” may include one or more devices for controlling fluid flow, such as one or more valves. It should be understood that the flow control device can be any combination of flow control devices, such as valves, that can establish an appropriate fluid flow. For example, in one embodiment, the flow control device includes a two-way valve. In one embodiment, the flow control device includes a three-way valve. In another embodiment, the flow control device includes a check valve and a two-way valve.

  Various devices may be included in the flow control device in the temperature regulation system.

In another embodiment, in the temperature regulation system, one flow controller is a two-way valve and another flow controller is a combination of a check valve and a two-way valve.

Determining the operation of the temperature regulation system for the purpose. Determining the operation of the temperature regulation system further includes positioning the flow control device such that at least two temperature regulators in the temperature regulation system are in series when the fluid volume is less than the threshold volume. including.

  A “threshold amount” is a specific amount of fluid flowing into a temperature regulation system that is sufficient for a particular number of temperature regulators in the system to operate in parallel flow without being damaged by insufficient fluid flow (eg, Flow rate). In some situations, a specific number of temperature regulators means all temperature regulators in the system. In some situations, a certain number of temperature regulators means fewer temperature regulators than all in the system.

  In one embodiment, the temperature regulation system has four regulators, each regulator requiring 25% of the maximum fluid flow supply to avoid breakage due to insufficient fluid flow. In the first situation of the embodiment, all four regulators are in parallel flow. In this first situation, the threshold amount is 100% of the maximum fluid flow supply. In the second situation of the embodiment, the four regulators are divided into two sets (for example, set 1 and set 2). Within each set, the temperature regulator is in series.
