The cooling capacity of refrigeration equipment is directly related to the operating conditions of the system. For the structure, speed and refrigerant types have been determined for the compressor, its cold production and energy consumption will change with the operating conditions and operation management of different and significant changes.

So far, the self-circulation evaporative cooling technology in hydro generators and turbine generators on the structure of the program have been successfully completed the small industrial unit prototype test, for the development of a larger capacity level of evaporative cooling unit has laid a solid foundation.

According to the “Ventilation and Air Conditioning Engineering Construction Quality Acceptance Specification” GB50243-2016 Article 4.2.3 stipulates that: the thickness of the steel plate of the air duct of the smoke exhaust system can be determined in accordance with the high-pressure system, and at the same time, it is clear that the thin sheet steel flange rectangular duct shall not be used for high-pressure air ducts. Then the point of contention: smoke exhaust system duct is a high-pressure system duct, in the end, thin steel plate flange connection can not be used for smoke exhaust system?

In the central air-conditioning chilled water, cooling water, condensate three water systems, the general design of the chilled water and cooling water systems pay considerable attention to the construction of the construction of quality management and pressure testing and other aspects of the construction is also done more considerate, running for some time after the problem of less, and the condensate system is relatively poor attention to some of the hotel building most of the air-conditioning end installed in the ceiling, due to the condensate discharge problems Problems of lagging, often in the wet ceiling damage can only be found after the problem, so the discharge of condensate should also attract sufficient attention.

Used to control the high pressure or exhaust pressure. When the pressure in the system exceeds the set safety value, the high pressure controller will shut down the compressor to prevent the excessive pressure from damaging the system or causing safety problems.
