Embodiment 1

[0038] A computer room air-conditioning and hot water system using a dual water source heat pump, comprising: a computer room 1, which is a closed structure; a number of cabinets 2 are arranged in the computer room 1 for placing heating equipment 6, wherein high-power heating equipment is placed on the upper part of the cabinet 2 The heating equipment with low power and low heat generation is placed in the lower part of the cabinet 2; the double water source heat pump 3 is used to regulate the cooling water temperature; the water inlet 19 and the water outlet 20 are used to pass in and discharge the cooling water; an intelligent controller 12 is also included , used to control the work of the whole system. The upper part of the machine room 1 is provided with a water-cooling channel 4 , and the water-cooling channel 4 is a completely sealed structure, and there is no air circulation with the machine room 1 . Heat collecting radiators 7 corresponding to the cabinets 2 are arran...

Embodiment 2

[0047] A method for controlling an air-conditioning and hot water system in a computer room using a dual-water-source heat pump, comprising the following steps:

[0048] (1) The intelligent controller 12 turns on the water inlet pump 18, the fan 9 and the water flow control valve 10, and monitors the temperature detected by the cabinet temperature sensor 11 and the radiator temperature sensor 21;

[0049] (2) The tap water of 10-20 ℃ as cooling water enters the water inlet 19 through the effect of the water inlet water pump 18, and the cooling water flowing in from the water inlet 19 extracts the temperature through the evaporator 32 of the double water source heat pump 3, and the temperature is reduced to 5- 15°C;

[0050] (3) The cooling water after cooling enters the water-cooling radiator 14 through the cold water pipe 15, and the cold air is sent into the cabinet 2 through the fan 9, and the cabinet 2 is cooled to ensure that the temperature in the cabinet 2 is 25 ± 5°C, ...

Abstract

The invention discloses a machine room air conditioner hot-water system with a double-water-source heat pump and a control method of the machine room air conditioner hot-water system. The machine room air conditioner hot-water system comprises a machine room, the double-water-source heat pump, a water inlet and a water outlet, wherein the machine room is of a closed structure, a plurality of machine cabinets are arranged in the machine room to be used for containing heating devices, the double-water-source heat pump is used for controlling the temperature of cooling water, and the water inlet and the water outlet are used for feeding and discharging the cooling water. The machine room air conditioner hot-water system further comprises an intelligent controller which is used for controlling work of the overall system; the double-water-source heat pump comprises a cooler and an evaporator, the water inlet is connected to the evaporator of the double-water-source heat pump and is further connected to a cold water pipe, and a hot water pipe is connected to the cooler of the double-water-source heat pump and is further connected with the water outlet; the cold water pipe and the hot water pipe are connected to a cooling system of each machine cabinet. By means of the machine room air conditioner hot-water system, the heat energy of the heating devices is recovered while the temperature of the machine cabinets is reduced, the recovered heat serves as a heat source to be supplied to heat utilization units, a PUE value of the machine room is greatly reduced to be smaller than one, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to a temperature control device, in particular to a computer room air-conditioning and hot water system using a double water source heat pump and a control method thereof. Background technique [0002] Due to the high density and high heat generation of the equipment in the computer and data processing room, the computer system has certain requirements on the temperature, humidity and dust concentration of the environment. The equipment in the computer room will emit a lot of waste heat during actual use. If The heat cannot be removed in time, and the high-temperature environment may reduce the operating efficiency of the equipment, and even cause equipment failures and other problems; therefore, this type of computer room needs to be cooled all the year round, and the computer room must be isolated from the outside world, through the air conditioning system to reduce the temperature of the unit . [0003] At present, the existin...
