Industrial air cooling direct evaporation type heat pump clean central air conditioner

Abstract

The air cooling directly evaporating clean industrial heat pump central air conditioner has indoor and outdoor controller to acquire the indoor air parameters, outdoor environment parameters and the state parameters to represent the operation status of the refrigerating system; regulates the power of the outdoor system via altering the number of operating outdoor units and other measures to regulate the cooling amount and heating amount; and controls the blowers, electronic expanding valves, solenoid valves, exhaust regulating valves, humidifier and other controllable parts, so as to ensure the positive pressure in purified room and comfortable indoor environment and to make the air conditioning system operate in optimal state.

Description

technical field [0001] The invention relates to an industrial central air conditioner. Background technique [0002] With the development of society and economy, the progress of science and technology. People's life values ​​have also undergone profound and huge changes. In order to ensure the life and health of the people, the Chinese government implemented the internationally accepted mandatory GMP certification for pharmaceutical (food) production, processing, storage and transportation enterprises from July 1, 1997. The core technical content of GMP certification work is: the indoor air environment (air cleanliness, temperature, humidity, fresh air volume) etc.) --- clean room (area) puts forward clear and strict technical standards. The purification central air-conditioning system technology and related products originally used in the fields of electronics (finishing machining) have been simply applied to the industrial fields such as medicine and food. Due to the d...

AI Technical Summary

Problems solved by technology

[0008] (4) It is difficult to control the (installation) air leakage rate of the high-efficiency filter, the test is difficult, the qualified rate of air leakage in one installation is low, the cost of rectification is high, and the cycle is long (it all depends on the professional quality, management level and sense of responsibility of the construction team);

[0009] (5) The replacement of high-efficiency filters requires secondary construction in the clean room (or even three or four times...) The damage to the ceiling will cause serious pollution to the clean room environment, construction, air leakage test, rectification, clean room self-cleaning, etc., which is a waste of money , and affect the normal production of enterprises

[0010] 2. The various links of the system are complex, decentralized, independent, and poorly related to control:

[0017] (1) High cost:

[0018] The electronic control parts are independent, and there is no associated control, resulting in troublesome operation, complicated operation management, and a large waste of operation management personnel and costs

[0019] (2) High energy consumption

[0020] The temperature and humidity control in the clean room are not directly related to the control of cold and heat sources. On the one hand, it is easy to cause indoor parameters out of control, and on the other hand, it causes a large amount of ineffective consumption of energy, such as: chilled water pumps of chillers, cooling towers, cooling water pumps (even cold water unit) Regardless of the demand in the clean room, they are running non-stop with an ineffective energy consumption of at least 20%

[0021] (3) High project cost

In addition, the system links are complex and the stakeholders are too scattered, which will inevitably lead to: large project differences, difficult management, and high project cost

[0023] (4) Engineering quality control is difficult

[0024] Generally speaking: the quality control of processing and installation (points and surfaces) at the construction site is much more difficult than the quality control of processing and installation under factory customized production conditions, and the cost input is also higher

Therefore, the current clean central air-conditioning system (project) is not only expensive! Fei Neng! And quality control is difficult
