At present, what type of chiller is more advanced, more energy saving, energy-saving effect?
First, the hotel can use the basic situationAt present, China's hotel industry energy consumption accounts for about 13% of the average hotel revenue.The hotel uses a general average of approximately:Air conditioner 51%Illumination 21%Electromechanical 17%Other 10%From the hotel can use the general proportion of view, air-conditioning can account for more than half of the hotel energy use, the greatest potential for energy saving. The following starts with the basic theory of freezing. The ways of energy saving for air conditioning are analyzed, and the corresponding methods and practice of energy saving are demonstrated.
Energy is the basic power to ensure the operation of various mechanical and electrical equipment in the hotel. With the rapid development of China's Moderno Hotel, although the hotel energy management level has been greatly improved, the energy consumption of the hotel is on the decline, but compared with developed countries, China's hotel industry is still a large gap in energy utilization efficiency. In view of the characteristics of electromechanical equipment in hotels, a brief introduction is made to the energy-saving technologies which are commonly used and proved to be comparatively mature. For specific energy-saving projects, the basic theoretical analysis is carried out to obtain the technical support of the basic theory. In this paper, the case of physical engineering is analyzed, and the main points of attention in energy saving method and its practical application are summarized. Designed for everyone to carry out energy-saving work reference.
Introduction and case analysis of comprehensive energy saving technology in hotelsWith the sustained and rapid development of China's national economy, the long-term growth of energy consumption has been driven. At present, China's energy supply has shown a tense situation. Vigorously promote conservation and consumption reduction, ease the bottleneck of resources, and realize the sustainable development of energy, environment and economic society are the core of China's energy use work.
Two, hotel air-conditioning energy-saving technologies and methods(1) a brief introduction to the basic theory of freezing1. Analysis of actual refrigeration cycle:Description of words during freezing cycle:A gaseous refrigerant that is 1 (T1, P1) out of an evaporator (4); is compressed into 2 state (T2, P2) after adiabatic compression of the compressor. The gas refrigerant is compressed, the condenser (2), isobaric cooling condensation, the state 3 (T3, P2) and the change of state 4 (T3, P2) of the liquid refrigerant, and then through the throttle valve (3) expanded to low pressure (P1), a 5 (T1, P1) the gas-liquid mixture. Among them, cryogenic (T1) low pressure (P1) liquid refrigerant in the evaporator (4) absorb the heat of the cold material, gasification under P1, into the state of 1 (T1, P1) gaseous refrigerant. The gaseous refrigerant is piped back into the compressor and a new cycle is started. This is the four cycle of the freezing cycle.
