Central air-conditioning system mainly includes two parts: hot and cold source host part and end equipment part, central air-conditioning self-control system, need to be equipped with automatic control system.

Analysis of the principle of energy conservation

Central air-conditioning system operating energy consumption is the most important energy consumption link in most public buildings, building energy consumption in the central air-conditioning system energy consumption of about 50%-70%, the recent national energy-saving targets and people's awareness of energy conservation gradually enhanced, reduce energy consumption enterprises not only increase disprofitability, but also advocate the national policy of energy conservation and emission reduction.

Optimising air-conditioned water system technology?

Water storage cold air-conditioning is to open the chiller host, refrigeration pump, cooling water pump, cooling tower and cooling water pump during the night power trough, and store it in the storage equipment in the form of electricity in the form of cold, and do not need to turn on the cooling host during the peak day power supply?

Dongguan Gree Central Air Conditioning Company - Huali Electrical and Mechanical, specializing in central air-conditioning installation projects, including process dust-free purification works, constant temperature and humidity air-conditioning design and sales and engineering installation.

Dust-free workshop purification project: control the cleanliness and temperature and humidity of the atmosphere contacted by the product, so that the product can be produced and manufactured in a good environmental space.

Ventilation pipes are metal or composite pipes for ventilation and air-conditioning engineering in industrial and civil buildings, which are municipal infrastructure sprees to allow air circulation and reduce the concentration of harmful gases.

Definition of constant humidity air conditioning

Refrigeration technology for air conditioning belongs to the scope of ordinary refrigeration, mainly using liquid vaporization refrigeration method. (Mainly the use of liquid vaporization process to absorb than latent heat, and the liquid pressure is different, its boiling is not the same, the lower the pressure, the lower the boiling point.) According to the different ways in which heat is transferred from a high temperature object to a low-temperature object, it can be divided into: vapor compression refrigeration and absorbent refrigeration.

Huali electrical and mechanical engaged in hot water engineering industry for many years, by the industry competent units of the government and the strong support of the heat pump water heater manufacturers
