Property Engineering Department Air Conditioning Work Summary Report

First of all, I would like to thank the company leaders for their strong support and affirmation of the air conditioning work of the Engineering Department in the year of xxxx. At the same time, I would like to thank all departments for their active cooperation and understanding of the air conditioning work of the Engineering Department this year! Here, I will report to the company about the completion of the air conditioning work of the engineering department xxxx.

In the year of xxxx, with the care and support of the company's leaders, under the hard work and unremitting efforts of all the staff of the engineering department, we have overcome difficulties such as fewer personnel and increased workload, and vigorously carried out maintenance and excavation potential technical transformation work. Actively solved various problems in equipment facilities, and made major breakthroughs in energy conservation and consumption reduction.

First, maintenance

There are many air-conditioning equipments in the building that operate for a long time and are in an aging state to varying degrees. Maintenance and operation are the main tasks of air-conditioning workers. Therefore, strengthening equipment maintenance and repair, improving the service life of equipment, and developing a scientific and reasonable operation plan is an important part of improving operational efficiency. On the basis of improving personnel skills, we have developed equipment operation plans, strengthened maintenance, and made air-conditioning equipment facilities in optimal operation, so as to achieve rational use of energy and save money.

In xxxx years, we carried out painting and anti-corrosion work on pipes and fans of aging and corrosion of air-conditioning ventilation system, and insured some air-conditioning pipes, and repaired 1 set of outdoor fume exhaust motor, which cured the building's smoke exhauster and blower. The air conditioner room replaced a dn250 gate valve, a dn200 gate valve, and a dn20 copper gate valve. It repaired the leakage problem of the cooling tower glass steel body, dealt with the water leakage problem of the softened water glass steel container, and made the moisture proof work of the air conditioner room. The air conditioner room is damaged by the short circuit of the control box switch, repairing the air conditioner main switch of the transformer room deformation, repairing and repairing all the electrical equipment of the air conditioner room, replacing the exhaust fan of the ls refrigerator, replacing the electromagnetic fan of the refrigerator One valve, the refrigerant liquefaction machine is filled with refrigerant r134a, the water seal and o-ring of the 1#, 3#, 4# circulation pump are replaced, the pressure gauge is replaced in the machine room, and the temperature meter is 5, the heat totalizer And the flow sensor has been verified, the heat pipes and valves have been maintained, and the pipes, valves and ends of the air-conditioning equipment facilities The end device has been maintained. In the spring and autumn, the indoor air conditioner was cleaned and the air filter and filter filter were cleaned. All air conditioner valves that were not opened were closed to reduce energy loss, and the winter antifreeze work was done. This is the largest workload. The most difficult job took more than four months. Usually, this work requires two people to complete the task, but because the engineering department has few staff, heavy tasks, and heavy workload, it is basically done by one person in the spring maintenance work, which undoubtedly increases the work. Difficulty, but the staff overcame all kinds of difficulties, completed the task of quality and quantity, and maintained maintenance on 132 households with 260 air conditioners. In the autumn, the engineering staff worked together to maintain 345 air conditioners for 133 and 1-4 floors.

Second, the transformation project

The engineering department actively cooperated with the construction department of the head office to renovate the two plate heat exchangers of the air-conditioned machine room, and replaced the heat exchanger with the original heat exchange area of ​​20 square meters with two heat exchangers with a heat exchange area of ​​48 square meters. In order to increase the heating flow, the two inverted dn150 plunger valves in the thermal well were re-installed correctly. The fan coil of the 11fh household that caused excessive noise due to the air conditioner motor was replaced. Disassemble and install the 26f air conditioning water tank once.

Third, energy saving

Energy conservation and consumption reduction is a key task of the engineering department this year. Under the leadership of the company, Mr. Chen led the staff of the engineering department to study the engineering management experience of advanced properties, improve the maintenance system, and keep the equipment in an efficient and energy-saving working state, completely reducing energy consumption, extending equipment life and saving expenses.

Central air-conditioning is a large energy consumer, and the work of central air-conditioning in energy conservation and consumption reduction will directly affect the profits of the entire property company. Under the leadership of Zhang and Chen, the air-conditioning workers have done a lot of work on energy conservation and consumption reduction, and have made major breakthroughs. Since the electricity price is subject to peak-to-valley charging, the peak electricity consumption is reduced as much as possible when electricity is used, and the valley electricity consumption is increased to reduce the energy consumption cost. Air-conditioning workers measure the temperature indoors every day, adjust the cooling and heating needs, sum up experience, save energy and reduce consumption.

Xxxx year summer cooling for 54 days, electricity 77820kwh, water 428 cubic meters, and XX year power saving 22988kwh, water saving 190.62 cubic meters, and XX year-on-year power saving 34020kwh. The power saving is all from the peak value of peace, and the electricity consumption in the valley is increased. In this way, the cost saved by using the peak-to-valley difference also accounts for a large proportion.

In the winter of xxxx, the heat for heating is 2204.85gj, the electricity is 82546kwh, and the water is 30.9 cubic meters. The xxxx year plan uses less than XX years of heat and electricity, which has achieved results in actual operation management. Among them, daily electricity consumption and XX year-on-year decrease by more than 150kwh, the heat is also low, but indoor heating is far better than Over the years, the heating needs of the households were initially met. If you continue to do so, the xxxx annual heating period ends, and the XX year can save more than 15,000kwh, and the heat is not higher than the previous year.

Only one central air-conditioning unit has reduced the cost of the company by more than 50,000 yuan in terms of energy saving and consumption reduction throughout the year. This will be the net profit created by the engineering department for the company.

Fourth, solve the heating problem

The heating problem is the biggest and most difficult legacy of the Tianzhi property. Due to the inappropriate introduction of heat sources during construction, the heating needs of the households cannot be met. Over the years, the complaint rate of households due to heating problems was 100%, and the dissatisfaction rate was 100%. In xxxx years, with the support of the company's leaders, the engineering department gave full play to the collective wisdom and strength and took every possible solution to solve the winter heating problem.

In October of xxxx, the engineering department actively cooperated with the construction department of the head office to replace two plate heat exchangers.

On November 29th, xxxx, the employees of the engineering department were not afraid of the cold and brought water operation, which solved the problem of the reverse valve installation of the main pipeline of the thermal well in the remaining problems of the project. Throughout the process, Zhang Assistant personally relied on it. The employees of the engineering department were not afraid of dirty, not afraid of being tired. They were not afraid of the temperature difference of more than 30 degrees inside and outside the well. They rushed to work in turn. After changing the valve, it was already more than 8 o'clock in the evening. The employees of the engineering department who sweated and licked the wet body went home to eat.

The staff of the engineering department worked hard to make a fuss from the heat source, actively communicated with the heat exchange station of the municipal company, and together with the leaders and technicians of the heat exchange station, technically analyzed the reasons for the poor heating effect, and told the truth to the truth. Ask the other party to increase the flow from 200 cubic meters per hour to 400 cubic meters per hour, increase the number of circulating pumps, increase the heat provided by the heat exchange station, and initially meet the heating needs of the households for the first time. The indoor temperature of the households has reached the minimum of 18 degrees as specified by Qingdao.

During the operation of the central air-conditioning system, the staff of the engineering department insisted on measuring the temperature in the households, paying attention to the weather changes, adjusting the operating status of the heating equipment and facilities according to the demand, not only ensuring the heating demand of the households, but also reducing the energy utilization to the lowest cost and solving them in time. Various problems encountered during heating.

Of course, this is only a preliminary solution to the heat source problem under the current heating conditions. The heating conditions are limited by the heating conditions of the municipal company. It is difficult to fully meet the needs of the business, and when the heating area reaches 10,000 square meters or more, it will not be able to meet the demand at all. From the perspective of long-term operation, it is necessary to introduce real “high temperature water” as a heat source to fundamentally solve the heating problem.

V. Pre-intervention of the property

The engineering department participated in the preliminary intervention work of the Huizhi Plaza project. In response to some problems found during the construction of the air-conditioning project, the engineering department promptly gave feedback to the Ministry of Construction. The engineering department also sent a special person to go to the scene to understand the construction quality, construction progress, etc., participate in the construction inspection and acceptance of the air-conditioning installation project, and put forward reasonable suggestions on the internal setting and function configuration of the property, participate in the completion acceptance of the property, and do a good job. The takeover and acceptance of the property will create a good foundation for future property management.

In the tense and busy xxxx years, the engineering staff worked together in the air-conditioning work, dedicated and dedicated, selfless dedication, enhanced maintenance skills and skills, enhanced service awareness and improved technical management.

Every penny saved by the engineering department will become the net profit of the property company. It is our goal to build the engineering department into a new profit-making department of the property company and create higher economic benefits for the company!

In xxxx, all employees of our engineering department will meet new challenges with a new spirit. Together with employees from other departments, we will provide a safe, comfortable and fast working environment for the owners and customers to ensure the normal function of the office building. Make the property value-added. We will show our talents in this harmonious, ideal and passionate environment and grow with the company. In the new year, we are confident that we will take the air-conditioning work to a new height and a new starting point with practical actions, and deliver a qualified answer to the company!
