Anti-freezing method for indirect evaporative water chilling unit capable of operating all year round and unit

Abstract

The invention belongs to the technical field of evaporative cooling in the energy field and particularly relates to an anti-freezing method for an indirect evaporative water chilling unit capable of operating all year round and a unit. A water inlet pipeline of the indirect evaporative water chilling unit is divided into two branches, one branch is connected with an inlet on the upper portion of a spray tower, a first valve is arranged on the first branch, and the other branch is connected with an air cooler, a water outlet pipeline on an air outlet side of the air cooler is connected with a water tank inlet on the lower portion of the spray tower, and a second valve is arranged on the other branch; a water outlet pipeline at the bottom of the spray tower is divided into two branches, one branch is connected with the air cooler, a self-circulation water pump is arranged on the branch, the other branch is connected with a user end, and a cold water circulation pump is arranged on the other branch; and a fan and an air outlet are arranged at the top inside the spray tower, and an air inlet is arranged on the lower portion of the lateral side. Operation conditions of the indirect evaporative water chilling unit are divided into three kinds in summer, transition seasons and winter, the indirect evaporative water chilling unit can be guaranteed to operate all year round, different modes are operated according to outdoor temperatures, the air cooler and the spray tower are guaranteed not to be damaged in winter, and accordingly, stable and reliable cold sources are provided all year round.

Description

technical field [0001] The invention belongs to the technical field of evaporative cooling in the field of energy, and in particular relates to an antifreeze indirect evaporative water chiller capable of operating throughout the year. Background technique [0002] The invention patent "A Method and Device for Indirect Evaporative Cooling, ZL 02100431.5" has been widely used in dry areas such as Xinjiang and Inner Mongolia. , The sensible heat sent to the end of the air conditioner takes away the sensible heat of the room, which satisfies the demand for indoor cooling. In addition to the field of comfort air conditioning, indirect evaporative cooling is also widely used in the field of technological air conditioning and industrial cooling that require cooling in winter, such as high-density data centers, machinery, rubber and other processing processes. However, these technological air conditioners and industrial cooling require stable cooling throughout the year, while the ...
