Problems solved by technology

At present, there are two main types of integrated chillers on the market: 1. Integrate conventional chillers, cooling towers, cooling pumps, refrigeration pumps, expansion tanks, pipelines and control devices into one, which can be installed outdoors without a dedicated machine room and The installation is simple, but the unit has the disadvantages of poor heat exchange efficiency, large water consumption, high noise, large volume, and low energy efficiency; 2. Integrating conventional chillers, evaporative condensers, cooling pumps, piping and control devices into one, can be Outdoor installation, high heat exchange efficiency and low water consumption, but the unit has the disadvantages of complex pipelines, long construction period, cumbersome installation, and poor operating efficiency
[0003] The above two types of integrated chillers will generate dirt on the heat exchange tubes after long-term operation, resulting in a decrease in heat exchange effect and poor efficiency. Therefore, the heat exchanger needs to be cleaned regularly according to the water quality.
Nowadays, chemical cleaning and high-pressure water cleaning are mostly used, which is not only time-consuming, labor-intensive, and expensive, but also needs to be shut down, which affects the cooling supply and brings a lot of inconvenience to users.
Moreover, the above two types of integrated chillers cannot realize the year-round cooling function, so they cannot be used in air-conditioning or process occasions with year-round cooling, and the scope of application is narrow

Abstract

The invention provides an integrated double-cooling water chilling unit. The integrated double-cooling water chilling unit has the advantages of being high in integration degree, convenient to install, efficient, capable of saving energy and wide in application range, a heat exchanger is cleaned without shutdown, and the integrated double-cooling water chilling unit is convenient to use. The integrated double-cooling water chilling unit particularly comprises a closed refrigeration cycling system. The closed refrigeration cycling system is formed by a compressor, an oil separator, a double-cooling condenser, an expanding and throttling device and an evaporator which are connected together in series sequentially. A freezing water cycling device is arranged between an inlet and an outlet of the evaporator. The double-cooling condenser comprises a catch basin and a spraying device. The spaying device is communicated with the catch basin through a spraying water cycling pump and a first water processing device. A cooling coil, a flow equalizing plate, filler and the catch basin are arranged below the spraying device in sequence. A cooling fan is arranged at the top of the double-cooling condenser. A pre-cooler and a water collector are arranged below the cooling fan in sequence. The catch basin is provided with a first automatic water supplement device, an overflow pipe, an automatic drainage device and an on-line dirt sucker. One end of the pre-cooler is connected with a gas outlet of the oil separator, and the other end of the pre-cooler is connected with the expanding and throttling device through the cooling coil.

Description

technical field [0001] The invention relates to the technical field of air conditioning units, in particular to an integrated double-cooling chiller. Background technique [0002] Due to its high efficiency, energy saving, compact structure, and convenient installation, integrated chillers have been more and more widely used in my country in recent years. At present, there are two main types of integrated chillers on the market: 1. Integrates conventional chillers, cooling towers, cooling pumps, refrigeration pumps, expansion tanks, pipelines and control devices, which can be installed outdoors without a dedicated machine room and The installation is simple, but the unit has the disadvantages of poor heat transfer efficiency, large water consumption, high noise, large volume, and low energy efficiency; 2. Integrating conventional chillers, evaporative condensers, cooling pumps, piping and control devices into one, can be Outdoor installation, high heat exchange efficiency a...
