When an element is referred to as being "mounted on," “engaged to,” "connected to," or "coupled to" another element, it may be directly on, engaged, connected or coupled to the other element. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed elements.
The present disclosure envisages a condenser unit. The condenser unit (herein after referred to as “condenser unit 100”) is described below with reference to Figure 1 through Figure 3.
The condenser unit 100 comprises a condenser 100A, and an auxiliary condenser 100B configured to cool the multiple indoor rack cooling units 104.
The condensers (100A and 100B) are placed outside a facility open to the atmosphere. Whereas the plurality of rack cooling units 104 is placed inside the facility. Each of the condensers (100A and 100B) of the condenser unit 100 and each of the rack cooling units 104 are configured to be in fluid communication with each other via conduits 106.
Each of the condensers (100A and 100B) is includes a condensation unit 103A, and at least one variable refrigerant flow (VRF) compressor 103B disposed therein. The VRF compressor 103B is in fluid communication with the condensation unit 103A and the plurality of rack cooling units 104 via the conduits 106.
The condensation unit 103A of the condensers (100A and 100B) is configured to condense the vapours of the cooling media into fluid. The VRF compressor 103B is in fluid communication with the each of the rack cooling units 104. The VRF compressor 103B is configured to circulate the condensed fluid to each of the rack cooling units 104. The VRF compressor 103B is further configured to circulate the condensed fluid to each of the rack cooling units 104 at a pre-determined rate.
In an embodiment, the condensed fluid is a cooling media. In another embodiment, the cooling media is a refrigerant. The VRF compressor 103B circulates the condensed fluid i.e. refrigerant which is condensed by a single condenser either 100A or 100B to cool multiple indoor the rack cooling units 104. The VRF compressor 103B and the conduits 106 are configured in such a manner that each of the rack cooling units 104 receives the condensed fluid in accordance with its requirement. Further, the VRF compressor 103B is configured to work at varying speeds that comply to the rate required thereby, allowing substantial energy savings at full load conditions.
In an embodiment, the condenser unit 100 may have at least one condenser. In another embodiment, the condenser unit 100 may have two or more than two condensers.
Figure 2 illustrates a condenser unit 100 having the condenser 100A and the auxiliary condenser 100B. The two condensers (100A and 100B) are disposed at an outdoor location and are in fluid communication with each of the indoor rack cooling units 104 via the conduits 106. Out of the two condensers (100A and 100B), only the condenser 100A is configured to cool the multiple indoor rack cooling units 104 at a time. The auxiliary condenser 100B is a standby unit and is configured to cool the multiple rack cooling units 104 when the condenser 100A is under standby state (rotation/ cascading mode) or any other failures, servicing or maintenance. Each of the indoor rack cooling units 104 is designed to optimize air distribution for servers and reduce core temperature of the indoor racks of equipments.
In an embodiment, the condenser unit 100 is configured to allow the condenser 100A to circulate the condensed fluid when the auxiliary condenser 100B is under standby state. In another embodiment, the condenser unit 100 is configured to allow the auxiliary condenser 100B to circulate condensed fluid via the conduits when the condenser 100A is under standby state.
In an operative configuration, when the condenser unit 100 is turned on, the condensation unit 103A of the condenser 100A starts condensation of vapours of a cooling media into fluid. The VRF compressor 103B of the condenser 100A circulates the condensed refrigerant (condensed fluid) from the condensation unit 103A to the indoor rack cooling units 104 via the conduits 106. Further, in an event if the condenser 100A undergoes in standby mode, the condenser unit 100 switches the auxiliary condenser 100B. The condensation unit 103A of the auxiliary condenser 100B is configured to condense vapours of a cooling media into fluid and the VRF compressor 103B of the auxiliary condenser 100B is configured to circulate the condensed fluid at a pre-determined rate similar to the condenser 100A to efficiently cool each of the rack cooling units 104. Similarly, upon servicing the condenser unit 100A, the condenser unit 100 again switches back the condenser 100A and turns off the auxiliary condenser 100B. Thus, the condensers (100A, 100B) ensure that the cooling process is not hampered.
The condenser unit 100 is a single outdoor unit which is used for efficient cooling of each of the multiple indoor rack cooling units 104. The condenser unit 100 of the present disclosure is compact, less noisy and is easily installed as compared to conventional condenser units that are large, bulky and generate lot of noise.
