Multi-working-condition air conditioner water chilling unit capable of preparing cold water with different temperatures at the same time

Abstract

The invention relates to a multi-working-condition air conditioner water chilling unit capable of preparing cold water of different temperatures at the same time. The air conditioner water chilling unit comprises a compressor, a condenser capable of supplying return water with the temperature ranging from 30 degrees to 35 degrees and the return water with the temperature ranging from 60 degrees to 65 degrees, an evaporator capable of supplying high-temperature cold water with the temperature ranging from 15 degrees to 20 degrees or low-temperature cold water with the temperature ranging from 7 degrees to 12 degrees, a flash evaporator with a quick ice slurry preparing function and an ice tank capable of supplying circulated chilled water for preparing ice slurry and chilled water with the temperature ranging from 0 degree to 5 degrees and used for deep fresh air dehumidification. By means of the water chilling unit, cold water with different temperatures can be supplied at the same time, the normal use requirements for high-quality heat extraction and high-quality dehumidification in an independent temperature and humidity control air conditioner system are met, the normal use requirement of a conventional air conditioner system is met, and the life hot water requirement is met, and the water chilling unit can be used in various air conditioner systems in the form of a universal core water chilling unit. The water chilling unit has the advantages that the water chilling unit is simple and reasonable in structure, reliable to work, capable of saving energy, convenient to use, high in universality, lower in both the arrangement cost and the daily use cost and has very high practicability and wide market application prospects.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment manufacturing, in particular to a multi-working-condition air-conditioning chiller capable of producing cold water at different temperatures at the same time. Background technique [0002] At present, there are more and more public buildings using central air-conditioning systems, and many problems such as the huge energy consumption of central air-conditioning systems and the unsatisfactory quality of indoor ambient air are becoming increasingly apparent. The energy-saving and further improvement of central air-conditioning systems The quality of indoor air has become a common concern and research topic of the whole society. For the air conditioning system, it is mainly responsible for the task of removing indoor waste heat, humidity, harmful gases and odors. The research shows that the removal of indoor residual humidity has the same requirements as the removal of harmful gas...

AI Technical Summary

Problems solved by technology

Therefore, the existing air-conditioning systems with independent temperature and humidity control generally have the following problems: 1. The structure is relatively complicated, and the workload and difficulty of installation and debugging are relatively large during installation, resulting in high system setup costs; 2. The unit occupies a large building space. It is not conducive to popularization; 3. The chiller used to remove residual humidity provides low-temperature cold water (that is, low-temperature cold source) that is conventionally around 7oC, which cannot fully meet the dryness requirements of fresh air deep dehumidification

Therefore, from the perspective of practicality and economy, it is not ideal, and it is necessary to improve and improve
