Dry type water-cooled water chilling unit

Abstract

The invention relates to a dry type water-cooled water chilling unit. The dry type water-cooled water chilling unit is composed of a shell and bases. Wrapping covers are arranged at the two ends of the shell. A chilled water outlet and a chilled water inlet are formed in each wrapping cover. A refrigerant water outlet pipe and a refrigerant water inlet pipe are arranged at the upper end of the shell. Thermal expansion valves are arranged between the refrigerant water outlet pipe and the refrigerant water inlet pipe. Safety valve connectors are arranged between one thermal expansion valve and the refrigerant water outlet pipe and between the other thermal expansion valve and the refrigerant water inlet pipe. An electromagnetic valve connector is arranged at the other end of each wrapping cover. A dry type evaporator is arranged in the shell. Dry type evaporator connectors are arranged at the lower ends of the electromagnetic valve connectors. An exhaust valve is arranged at the lower end of the shell. The energy efficiency ratio of the whole unit can reach 4.85 kw / kW, and the operating mode is intelligent; the dry type water-cooled water chilling unit is more suitable for operating in a partial-load mode, the operating load of the unit is adjusted reasonably according to detecting parameters, and the excellent partial-load operating efficiency is achieved; and the energy-saving effect is quite good, and the refrigeration effect and heat exchange effect of the whole dry type water-cooled water chilling unit are good after the dry type water-cooled water chilling unit is assembled.

Description

technical field [0001] The invention relates to a dry water-cooled chiller. Background technique [0002] At present, dry-type water-cooled chillers have the advantages of small size, high efficiency, low noise, long life, and easy operation. They can provide chilled water for various centralized air-conditioning systems and processes, and are widely used in hotels, hospitals, and shopping malls. However, Existing dry-type water-cooled chillers have defects in both function and use, and their refrigeration and heat exchange effects are not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dry-type water-cooled chiller with good refrigeration and heat exchange effects. [0004] In order to solve the above technical problems, the present invention provides a dry-type water-cooled chiller, which consists of a shell and a base. The two ends of the shell are covered with a cover, and the cover is provided with ...
