Detailed Description of Embodiments of the Invention

In the following description, numerous specific details are set forth in order to provide a thorough understanding of various illustrative embodiments of the invention. It will be understood, however, to one skilled in the art, that embodiments of the invention may be practiced without some or all of these specific details. It is understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the invention. In the drawings, like reference numerals refer to same or similar functionalities or features throughout the several views. Figure 1 shows a schematic diagram illustrating a recreational facility 10 according to one embodiment of the invention. Referring to Figure 1 , in this embodiment, the recreational facility 10 comprises a substantially enclosed housing structure 100 and six temperature control systems (TCS) 101. Each temperature control system 101 includes an air cooling device (ACD) (e.g. 102a, 102b, 102c, 102d), a temperature sensor (TS) 104 and a controller module 106.

As shown in Figure 1 , the substantially enclosed housing structure 100 provides six interconnected spatial zones which are disposed in a tubular arrangement. Each of the six spatial zones is configured to be maintained at one of six different predetermined temperatures, respectively, e.g. 20 °C (degree Celsius), 15 °C, 10 °C, 5 °C, 0 °C and -5 °C. In order to provide a visitor in the recreational facility 10 with the experience of temperature changes to simulate season changes, the predetermined temperatures over the plurality of spatial zones may form a descending or ascending sequence of temperature values. In this embodiment, as shown in Figure 1 , from one end to an opposite end of the recreational facility 10, the six predetermined temperatures over the six spatial zones are arranged in the following sequence: 20 °C Zone, 15 °C Zone, 10 °C Zone, 5 °C Zone, 0 °C Zone, and -5 °C Zone to simulate summer, autumn/spring and winter temperatures.

In order to provide a winter facility in the recreational facility 10, the recreational facility 10 may further include at least one snow generator 110 disposed in one or more of the spatial zones, e.g. in the 0 °C Zone and/or the -5 °C Zone. The snow generator 110 is to generate snow and is suitably disposed to direct snow to the corresponding spatial zone to create snowfall or snow scene therein. Winter-specific activities may be conducted in the corresponding spatial zone. The recreational facility 10 may further include a snow melting device 111 which is provided at the bottom of the corresponding spatial zone (e.g. underground) for disposal of snow. As shown in Figure 2, the snow melting device 111 includes a receptacle

112, an inlet pipe 114 and an outlet pipe 116 which are both disposed in fluid communication with the receptacle 112. The receptacle 112 is disposed to receive snow discharged from the snow generator 1 0 and/or to be disposed from the corresponding spatial zone. The inlet pipe 114 is disposed to receive water (e.g. seawater) into the receptacle 112 to melt the snow received in the receptacle 112. The outlet pipe 116 is disposed to discharge the melted snow from the receptacle 112, thereby removing snow from the corresponding spatial zone. The outlet pipe 116 may be wrapped by glass wool and silver paper to inhibit heat transfer between the inside and outside of the outlet pipe 1 6. The receptacle 112 may be attached or provided with a multi-layer structure which is to provide waterproofing, insulation and structural support. The multi-layer structure may include a water-proof layer 12, an insulating layer 14 and a base layer 16, wherein the multi-layer structure is juxtaposed to the receptacle 112. In each of the temperature control systems 101 , the air cooling device is to provide forced cool air to the respective one of the spatial zones; the temperature sensor 104 is to sense prevailing temperature in the respective one of the spatial zones; the controller module 106 is coupled to the air cooling device and the temperature sensor 104 and configured to control the air cooling device based on the temperature data determined by the temperature sensor 104 and the corresponding predetermined temperature assigned to the corresponding spatial zone.

It should be noted that different types of air cooling devices may be employed based on the pre-determined temperature values assigned. As known by a skilled person in the art, an air cooling device typically includes the following components: compressor, evaporator(s), expansion valve(s) and condenser. Different type of air cooling device may have different type of components. The criteria for selecting appropriate air cooling device for a spatial zone are explained below.

If the predetermined temperature assigned to a spatial zone, is above 16 °C, a first-type air cooling device 102a (ACD I) is provided, which has an operative temperature range of at least 16 °C. As well known by a person skilled in the art, a traditional air conditioning device can only work in a temperature range of at least 16°C. Therefore, preferably, the first-type air cooling device 102a may be a traditional air conditioning device.

If the predetermined temperature is between 5°C to 16 °C (normally excluding 5°C and 16°C), then a second-type air cooling device 102 b (ACD II) is provided, which has an operative temperature range between 5 °C and 16°C, e.g. DE 12.5 air cooler device.

If the predetermined temperature is between 0°C and 5 °C (normally including 0°C and 5°C), then a third-type air cooling device 102c (ACD III) is provided, which has an operative temperature range between 0 °C and 5°C, e.g. DJ 12.5 air cooler device. If the predetermined temperature is less than 0 °C, then a fourth-type of air cooling device 102d (ACD IV) is provided, which has an operative temperature less than 0°C, e.g. DD 12.5 air cooler device.

According to the above criteria for selecting an appropriate air cooling device as explained above, in this embodiment as shown in Figure 1 , a first-type air cooling device 102a (TCE I) is selected and provided in the 20 °C Zone; a second-type air cooling device 102b (TCE II) is selected and provided in each of the 15 °C Zone and 10 °C Zone; a third-type of air cooling device 102c (TCE Ml) is selected and provided in each of the 5 °C Zone and 0 °C Zone; a fourth-type of air cooling device 102d (TCE IV) is selected and provided in the -5 °C Zone.

It is to be noted that as known by a skilled person in the art, a traditional air conditioning device may use water to realize heat exchanging during a cycle of air conditioning refrigeration process. However, according to one embodiment of the invention, the air cooling device which has an operative temperature less than 16°C, e.g. the second-type air cooling device 102b, third-type of air cooling device 102c and the fourth-type of air cooling device 102c, may be a waterless system. In a cycle of air conditioning refrigeration process in the waterless system, one type of refrigerant, e.g. Freon, R22 or R404a, is directly used for heat exchanging during the refrigeration process. Specifically, the evaporator(s) of the air cooling device is directly provided with throttled refrigerant instead of water. After heat exchanging, the temperature of the refrigerant increases, then the refrigerant is to be compressed by a compressor, condensed by a condenser, and finally returned to the evaporator(s) after a process of throttling expansion.

According to the embodiment of the invention shown in Figure 1 , the recreational facility 10 may further include at least one air curtain machine (ACM) disposed to provide an air curtain between two adjacent spatial zones, especially, when different types of air cooling devices are used in the two adjacent spatial zones. Referring to Figure 1 , in this embodiment, a first air curtain machine 108 is disposed between the 20 °C Zone (an ACD I is used in this spatial zone) and the 15 °C Zone (an ACD II is used in this spatial zone) to provide a controlled air stream layer to inhibit or at least reduce air circulation between these two adjacent spatial zones. Preferably, the controlled air stream layer substantially traverses a passage connecting the two adjacent spatial zones. A second air curtain machine 108 is disposed in between the 10 °C Zone and the 5 °C Zone, since in these two spatial zones, a ACD II and a ACD III are used respectively. Preferably, the second air curtain machine 108 is disposed to provide a controlled air stream layer substantially traversing a passage connecting the two adjacent spatial zones to inhibit or at least reduce air circulation between these two adjacent spatial zones. In the embodiments of the invention, the controller module 106 of each temperature control system may be disposed in a separate control room or disposed on-site with the compressor of an air cooling device.

Further, the recreation facility 10 as shown in Figure 1 may further comprise at least one air blower device 120 disposed to direct a circulating air stream into at least one of the spatial zones to provide air circulation within the at least one of the spatial zones.

According to one embodiment of the invention, the substantially closed housing structure 100 in this invention may be made of multi-layer organic glass, e.g. five-layer organic glass, to keep surface of the substantially closed housing structure 100 free of moisture such that a clear view of the environment external to the substantially enclosed housing structure 100 is provided to visitors when visitors are situated within the substantially enclosed housing structure 100.

According to one embodiment of the invention, each of the controller modules 106 may include a temperature data receiving module 202, a Programmable Logical controller (PLC) module 204 and an inverter 206, as shown in Figure 3.

Referring to Figure 3, the temperature data receiving module 202 is configured to receive a temperature data from the corresponding/connected temperature sensor 104. The PLC module 204 is configured to compare the received temperature data with a pre-determined temperature value and based on the comparison result, generate a voltage signal for controlling fan speed in the corresponding air cooling device and/or adjust quantity of evaporators in operation in the corresponding air cooling device. Typically, the quantity of operating evaporators can be adjusted by controlling switch state of each electromagnetic valve corresponding to the evaporators. The inverter 206 is configured to generate a frequency signal based on the voltage signal received from the PLC module 204 and is further configured to control fan speed in the corresponding air cooling device according to the generated frequency signal. The embodiments of the invention also provide a method for providing a recreational facility. Figure 4 is a flow chart illustrating a method for providing a recreational facility according to one embodiment of the invention.

In block 1001 , the method includes providing a substantially enclosed housing structure having a plurality of interconnected spatial zones configured to be maintained at a plurality of predetermined temperatures including zero or subzero temperature and above-zero temperature, wherein each of the spatial zones is configured to be maintained at one of the plurality of predetermined temperatures which is different from the remaining of the spatial zones.

According to one embodiment of the invention, a method of temperature control comprises Blocks 2001 to 2003, as shown in Figure 5.

In block 2001 , the method of temperature control includes providing, by an air cooling device, forced cool air to the respective one of the spatial zones;

In block 2002, the method includes sensing or detecting, by a temperature sensor, prevailing temperature in the respective one of the spatial zones; In block 2003, the method includes controlling, by a controller module coupled to the air cooling device and the temperature sensor, the air cooling device based on the sensed temperature and the one of the plurality of predetermined temperatures. In embodiments of the invention, the plurality of spatial zones include at least one first spatial zone which is configured to be maintained at a predetermined winter temperature at zero or sub-zero temperature, at least one second spatial zone which is configured to be maintained at a predetermined spring/autumn temperature between 5 to 15 degree Celsius, and at least one third spatial zone which is configured to be maintained at a predetermined summer temperature at above 16 degree Celsius, wherein the at least one second spatial zone is interposed between the at least one first spatial zone and the at least one third spatial zone.

Preferably, the plurality of spatial zones are disposed in a tubular arrangement and wherein the plurality of predetermined temperatures over the plurality of spatial zones form a descending or ascending sequence of temperature values. Thus, when a visitor moves through the spatial zones from one end to an opposite end of the recreational facility, the visitor would experience temperature changes that simulate or replicate season changes. In order to provide snowfall or snow view in the recreational facility, the method may further include: providing a snow generator in one of the at least one first spatial zone to provide snow therein.

Preferably, the method further includes: providing a snow melting device which is disposed at a bottom of the one of the at least one first spatial zone, wherein the snow melting device including a receptacle, an inlet pipe and an outlet pipe which are both disposed in fluid communication with the receptacle, wherein the receptacle is disposed to receive snow, wherein the inlet pipe is disposed to receive sea water into the receptacle to melt the snow received in the receptacle, and wherein the outlet pipe is disposed to discharge the melted snow from the receptacle.

As mentioned above, the air cooling device in each of the temperature control systems may be selected based on one of the plurality of predetermined temperatures- The detailed method for selecting an appropriate air cooling device has been described above.

Further, if different air cooling devices are used in adjacent spatial zones, the method may further comprise: providing an air curtain machine which is disposed to direct a controlled air stream layer between the adjacent spatial zones to inhibit air circulation between the adjacent spatial zones. Preferably, the controlled air stream layer is provided substantially traversing a passage connecting the adjacent spatial zones.
