Embodiment Construction
[0015] The present invention provides a flooded screw chiller. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] Such as figure 1 The shown flooded screw chiller includes a main engine 100 (that is, a screw compressor), an evaporator 200, an oil separator 300, a low-pressure circulation barrel 400, and a horizontal condenser 500. The refrigerant of the main engine 100 The outlet is connected to the refrigerant inlet of the oil separator 300, the refrigerant outlet of the oil separator 300 is connected to the inlet of the evaporator 200, the outlet of the evaporator 200 is connected to the inlet of the accumulator 600, and the outlet of the accumulator 600 is Connect the refrigerant inlet of the low...

The invention provides a water cooling unit of a full-liquid type screw machine. The water cooling unit comprises a main engine, an evaporator, an oil separator, a low-pressure circulation barrel and a horizontal evaporator. A refrigerant outlet of the main engine is connected with a refrigerant inlet of the oil separator. A refrigerant outlet of the oil separator is connected with an inlet of the evaporator. An outlet of the evaporator is connected with a refrigerant inlet of the low-pressure circulation barrel. A refrigerant outlet of the low-pressure circulation barrel is connected with a refrigerant inlet of the horizontal condenser. A refrigerant outlet of the horizontal condenser is connected with an air inlet of the low-pressure circulation barrel. An air outlet of the low-pressure circulation barrel is connected with a refrigerant inlet of the main engine. The water cooling unit of the full-liquid type screw machine has the beneficial effects that ammonia is capable of saving refrigeration energy and good in refrigerating effect and freon is safe and convenient to use, and the refrigerating efficiency of the system with freon as a refrigerant is greatly improved; the comprehensive energy efficiency ratio is remarkably increased, energy consumption is greatly reduced, and thus long-term stable automatic operation can be achieved; and the problems that an existing water cooling unit is high in energy consumption and operation and maintaining cost are solved.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a flooded screw chiller. Background technique [0002] The existing chillers are mainly divided into Freon refrigeration and ammonia refrigeration according to the refrigerant. Compared with Freon, ammonia has a better refrigeration effect and energy-saving refrigeration, but compared with Freon chillers, it has lower safety and higher system maintenance costs. Freon Chillers are usually characterized by safety, reliability and easy maintenance. Moreover, since the chillers using the two refrigerants have different refrigeration equipment settings, they cannot be used universally, which makes it impossible for the existing chillers to simultaneously have the effects of high cooling efficiency and high safety. [0003] Therefore, prior art still needs further improvement. Contents of the invention [0004] In view of the deficiencies in the prior art, the present inventi...
