Problems solved by technology

These methods have led to some new problems. Because the outdoor air quality is not guaranteed, the base station equipment is damaged; simply exchanging a single surface cooler for a natural cooling source cannot meet the demand, resulting in repeated investment; simply using the surface cooler outdoors for natural cooling The capacity sometimes meets the load demand and sometimes does not meet the load demand, resulting in frequent start and stop of the chiller, which increases unnecessary energy consumption and equipment loss

Embodiment Construction

[0019] The content of the present invention will be described in detail below in conjunction with the drawings and specific embodiments. It should be understood that the present invention is not limited to the following preferred embodiments, which are only used as illustrations of the present invention.

[0020] Such as figure 1. as shown, figure 1. The natural cold source collector 5, evaporator 6, cooling water pipeline 17, refrigerant pipeline 18, refrigerant water pipeline 19 and refrigerant water pipeline 20 in the unit are all schematic diagrams of the system principle. The cooling water in the cooling water circulation pool 10 at the lower part of the indoor unit 1 of the present invention is sent to the nozzle 11 via the cooling water circulation pump 9 and the cooling water pipeline 17, and sprayed on the finned coils of the evaporative condenser 4 and the natural cold source collector 5 , and form a water film on the outer surface of the coil, the falling water fi...

Abstract

The invention relates to a natural cold source cooling water chiller which comprises an outdoor unit and an indoor unit, wherein the outdoor unit mainly consists of a refrigeration system composed of a totally-enclosed scroll compressor, an evaporator, an evaporative condenser and a natural cold source collection device, and a water channel circulating system with a three-way valve so as to realize the mechanical refrigeration of the evaporative condenser and the evaporative cooling and the air cooling of the natural cold source collection device. The water chiller is characterized in that the evaporative condenser and the high-efficiency natural cold source collection device are arranged simultaneously above a cooling circulating water pool, and an axial-flow fan is installed on upper space. When the outdoor wet-bulb temperature is higher than 6 DEG C to 8 DEG C, the evaporative condenser is mainly used to realize refrigeration, when the outdoor wet-bulb temperature is lower than 6 DEG C to 8 DEG C and higher than 0 DEG C and 2 DEG C, the natural cold source collection device which is in the form of cooling tower spraying is mainly used to realize the evaporative cooling, and when the outdoor wet-bulb temperature is lower than 0 DEG Cto 2 DEG C, the natural cold source collection device which is in the form of air cooling is mainly used to realize cooling.

Description

technical field [0001] The invention relates to a natural cold source chiller, more specifically, to a constant temperature and humidity chiller equipped with a high-efficiency natural cold source collector and an evaporative condenser. Background technique [0002] At present, for places with continuous high heat generation, such as telecommunication base stations, information equipment rooms, etc., standard split air conditioners are generally used. This traditional split air conditioner uses the operation of an outdoor cooler to meet the cooling load requirements inside the base station, and does not take into account the use of natural cooling sources in cold seasons. Thus, the air conditioner needs a lot of energy due to continuous operation. There are also a few who have adopted some means to utilize the natural cold source in the cold season, such as directly introducing outdoor air to cool the equipment, or simply using the surface cooler to exchange for natural coo...
