Novel heat pipe machine room air conditioner system and operating method thereof

Abstract

The invention discloses a novel heat pipe machine room air conditioner system and an operating method thereof. The system comprises a first-stage refrigerant loop and a second-stage refrigerant loop which are connected through a heat exchanger. The second-stage refrigerant loop comprises a plurality of terminals. Each terminal is provided with a speed-adjustable draught fan and a temperature sensor used for detecting the supply air temperature or the return air temperature of the terminal. When the supply air temperature or the return air temperature of each terminal is outside the corresponding target temperature range, the rotating speed of the draught fans or the evaporating temperature of refrigerant in the first-stage refrigerant loop is adjusted, so that the supply air temperature orthe return air temperature of the terminal is adjusted to be within the corresponding target temperature range. The novel heat pipe machine room air conditioner system has the beneficial effects thatthrough one-time heat exchange of refrigerant-refrigerant in the two stages of refrigerant loops, heat loss caused by multiple times of heat exchange and a too long pipe can be effectively avoided; moreover, the first-stage refrigerant loop makes full use of outdoor air to drive a natural cold source, and more energy is saved.

Description

technical field [0001] The invention relates to a machine room air-conditioning system, in particular to a novel heat pipe machine room air-conditioning system and an operating method thereof. Background technique [0002] As a new type of computer room air conditioner, the heat pipe air conditioner relies on the phase change of its internal working liquid to achieve heat exchange, while the condenser is placed at a high place, and the working liquid flows back to the end only by gravity. During this process, no power is required, which is highly efficient and energy-saving. Compared with the traditional chilled water system, the heat pipe system does not have to worry about water leakage and damage to the equipment in the cabinet, and has high reliability. Based on the above advantages, the heat pipe system is gradually favored by some innovative computer rooms. [0003] However, the heat pipe system relies too much on the chilled water system provided by the machine room,...

Problems solved by technology

[0003] However, the heat pipe system relies too much on the chilled water system provided by the machine room, requiring water pumps to overcome the resistance of the pipe network to transport chilled water, and the water pump is one of the main energy-consuming equipment of the air-conditioning system. Unreasonable pipeline design or pressure balance device will lead to energy consumption. waste of

For small computer rooms without preset chilled water systems, chillers and water pump systems need to be purchased, which not only requires high investment costs, but also takes up building space to place equipment, and after two heat exchanges between refrigerant-water-refrigerant, there will be more heat exchange. heat loss
