Energy-saving method for forest air conditioner

Abstract

The invention relates to the field of material and energy and the field of environmental protection and discloses a method and process for achieving energy saving based on a manual simulation forest microclimate system under air conditioner application through Carnot cycle. Water is led in to serve as a medium for a conveying and distribution system. through the scheme that a cold water cooling capacity recovery method is adopted, the temperature of a condenser is lowered, secondary latent heat of a refrigerant is used, the temperature condition of an evaporator is raised, heat and cooling capacity output efficiency is improved and fresh air ventilation removal is replaced by a method that indoor carbon dioxide, TVOC, air dust microorganism and other pollutants are removed by washing air, 10%-40% energy is saved in the usage process of the air conditioner.

Description

technical field [0001] The invention relates to the field of materials and energy and the field of environmental protection. Forest air conditioning is the abbreviation of artificially simulated forest microclimate. The invention is a new energy-saving method of air conditioning, which can save energy by 10% to 40% during the use of the air conditioner. Background technique [0002] The current practical microclimate environment--air conditioning technology has been developed for more than 80 years. Since the power consumption of air conditioners in modern buildings is a large energy consumer, it has developed to a very high level in energy saving, comfort, and dust-free spaces. The 18°C ​​temperature of Gree air conditioners The cooling efficiency COP of the high-temperature cold water system reaches above 8.5. In terms of energy saving, through the invention of the electronic expansion valve and motor frequency conversion, the invention of adjusting the throttling coefficie...

Problems solved by technology

[0028] 1. Air-conditioning technology assumes that the outdoor air is clean, which cannot be solved. When the smog is severe, the air quality of the air-conditioned environment cannot be solved. People's pursuit of quality of life is constantly improving. With the increasing number of cars and the increasing process requirements of factories, The environmental protection issues involved are serious; there is no substantial improvement in the air in a short period of time. In order to protect the health of the people, a high-quality air environment in small spaces is urgently needed; under the concept that health is more important than money, high-quality air is most people's pursuit

[0029] 2. In the air-conditioning environment of commercial buildings, because the air quality is not high, people often open windows for ventilation due to bad habits of use, and the cold leakage is serious, so that the original design air-conditioning power is insufficient, and the standard requirement for chilled water is 7-11°C; but Most of the time during the peak period can only be maintained at 10-13°C; the relative humidity of the air environment often exceeds 65%; according to the Fanger comfort equation, it can be predicted that most air-conditioning users will feel uncomfortable; such bad habits cause multiple vicious circles, The operator will reduce the fresh air volume or directly disable the fresh air, resulting in 40% higher energy consumption of commercial buildings in my country than in advanced foreign countries; this is a great waste

In 2003, the SARS epidemic raised people's requirements for air disinfection. The current air purification technology is mainly electrostatic dust removal and FFU. The ozone generated by static electricity will harm the human body; the high energy consumption and cost of FFU are also unaffordable for many companies. Moreover, the noise and process requirements are high, and it is difficult to meet the conditions in practice.

[0033] Problem 1: Humidity is difficult to control. With the current central air-conditioning technology, when the humidity needs to be strictly controlled, it is completed by the air handling unit. The process design: refrigeration-reheating-rehumidification cycle process, energy consumption is wasted, won the Nobel Prize in Physics Award-winning scientist Steven Chu criticizes air-conditioning experts: Tossing around, there must be something wrong【1】

[0034] Problem 2: The dust removal efficiency of the fresh air fan is low, so it cannot be used in hazy weather or the electrostatic precipitator fresh air system has the defect of remaining charged dust

[0035] Difficulty 3: It is difficult to effectively control indoor carbon dioxide content, remove VOC, odor, and eliminate the root cause of air-conditioning diseases caused by bacteria
