Embodiment 1

[0039] Such as figure 1 As shown, the cooling system provided by the present invention using a natural cooling source provided by the present embodiment includes: a cooling device 8 for a machine room, a constant temperature layer, an outdoor cooling device and a controller 11, and a cold medium 1 is built in the constant temperature layer, and the The machine room cooling equipment 8 can exchange heat with the cold medium 1 through the buried water pipe; the machine room cooling equipment 8 can exchange heat with the outdoor cooling equipment through the natural water pipe, and the natural water pipe can communicate with the buried water pipe communication; the controller 11 controls the cooling device 8 of the machine room to exchange heat with the cooling medium 1 and / or the outdoor cooling device according to the outdoor air temperature sensor t3.

[0040]Specifically, when the dry bulb temperature at room temperature is lower than the set temperature of the computer room,...

Embodiment 2

[0060] This embodiment is basically the same as Embodiment 1, except that a fire extinguishing system is provided in the machine room 50 .

[0061] Such as figure 2 As shown, the fire extinguishing system provided includes a fire extinguishing device and a controller 11; the fire extinguishing device includes an exhaust pipe 13, a valve arranged on the exhaust pipe 13, a smoke detector 17 and a temperature detector 18 arranged in the machine room; Valve, smoke detector 17 and temperature detector 18 are all electrically connected to controller 11; It can control to open the valve and activate the fire extinguishing device to extinguish the fire.

[0062] In this embodiment, the smoke detector 17 and the temperature detector 18 respectively monitor the smoke concentration and temperature in each machine room, when the smoke concentration in the machine room exceeds a preset value or the temperature in the machine room exceeds a preset value , indicating that there is a fire ...

Abstract

The invention provides a cooling system using a natural cold source and a machine room thereof. The cooling system using the natural cold source comprises machine room cooling equipment, a constant temperature layer, outdoor cooling equipment and a controller. A cold medium is arranged in the constant temperature layer, and the machine room cooling equipment can exchange heat with the cold medium through a buried water pipe. The machine room cooling equipment can exchange heat with the outdoor cooling equipment through a natural water pipe, and the natural water pipe can be communicated with the buried water pipe. And the controller controls the machine room cooling equipment to exchange heat with the cold medium and / or the outdoor cooling equipment according to an outdoor air temperature sensor. According to the scheme, the controller controls the machine room cooling equipment to exchange heat with the cold medium and / or the outdoor cooling equipment according to the outdoor air temperature sensor, underground constant-temperature cold energy and the air cooling natural cooling technology are combined, the energy is supplied to the cooling system of a data center for use, it is guaranteed that the temperature of the cold source is reliable, electric refrigeration is not needed, power consumption can be reduced, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of data computer rooms, in particular to a cooling system using a natural cold source and a computer room thereof. Background technique [0002] The construction scale and number of data computer rooms are increasing year by year. Due to the characteristics of the computer room itself, the heat is relatively concentrated and has a high sensible heat ratio, and the energy consumption of the air conditioner in the computer room throughout the year accounts for about 40% of the total energy consumption. How to reduce power consumption? Efficiency is a direction of current efforts. [0003] Conventional cooling systems include electric-driven cooling, or data center air conditioners that combine natural cooling and mechanical cooling. Electric-driven cooling consumes a lot of energy and requires high investment. The composite refrigeration and air-conditioning system using natural cooling technology can use par...
