4.2 FCU Fan coil to see from the overall level of similar products, compared with similar, but compared with foreign advanced level, the main difference is power consumption, weight and noise aspects of the coil.

Units from the perspective of the summer cooling energy consumption: centrifugal and screw chillers OEER the highest [link widoczny dla zalogowanych], two steam effect LiBr absorption chillers OEER minimum; winter heating: screw, piston pump cold hot water unit OEER highest, lowest electric hot water unit, that the highest energy consumption.

2 HVAC interior design to determine the temperature
By Chongqing, Shanghai, Guangzhou and other parts of proven, low indoor temperature in summer or winter than 1 1 [link widoczny dla zalogowanych], except HVAC investment increased by 6% to 8% in big things, increase the indoor outside temperature does not meet the hygiene requirements. Comfort air conditioning in summer is the ideal indoor temperature lower than the outdoor ambient temperature 5-8 for good.

(1) select the water pump is a pump according to the design value of search parameters to determine the sample plate, rather than pump water pump characteristic curve of the selected model;

this paper, the design staff to strengthen management, equipment engineers to speed up the implementation of a registration system, HVAC Air conditioning Temperature determination of interior design, air conditioning and heat sources, air conditioning units and terminal equipment, air-conditioning water system, to strengthen Central air conditioning Management, and actively promote the water loop Heat Pump Using heat recovery, variable air volume, variable volume systems, energy-saving technology, and energy efficiency of central air conditioning and discuss relevant issues.

(3) high flow and small temperature difference is widespread, the design for, and generally the return water temperature difference 5 , but by the measurement, return water temperature difference of chilled water in summer is better for 3 , less Only 1-1.5 , causing the ac
4.1 air-conditioning unit Fan flow unit should be selected, matching a reasonable pressure, less air leakage, the air transportation system a few large units.
3 cold and heat sources Central air conditioning energy consumption generally consists of three components, namely (1) cold and heat source; (2) Air conditioning unit terminal equipment; (3) Water or air transportation system. Energy consumption in the three-part, cold and heat source energy consumption accounts for about half of total energy consumption is an important part of energy-saving air-conditioning. If you are the respective consumption of energy converted into primary energy [link widoczny dla zalogowanych], the unit can use various types of primary energy consumption per unit time energy of the system to take the cold or heat comparison, this article uses a primary energy efficiency OEER (W / W) to represent .

5 air conditioning system General conditioning water system transmission and distribution of electricity, heating in winter, about the building during the power consumption of 20-25%; summer cooling period of about 12-24%, thus saving the water system has significance.
(2) at the end of each water loop for water balance calculation, the pressure differences between each end of the loop also take effective measures, so the hydraulic, thermal imbalance is serious;

4 air conditioning units, and terminal equipment
97 years of statistics, domestic production Fan Coil Unit The factory has more than 200, annual output of 60-80 million units; air conditioning units are also more than 100, the output of 5 million units.
1 HVAC projects, should more detailed cooling and heating load calculations and energy-saving measures taken by those present, many designers who are taking energy conservation measures, many designers are now using a combined budget targets Great, so cold, the heat source host long-term low load, low efficiency of the next.
