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 hum...
