Problems solved by technology
[0003] Because the energy efficiency of outdoor units of various capacities is different, especially in the case of partial load, the conventional selection method does not consider this difference, so most of the multi-connected air conditioning systems designed are not the most optimal. Energy saving

Embodiment Construction
[0021] By the following figure 1 Specifically explained.
[0022] figure 1 Shows a method of multi-split air conditioning system of the present invention, selection of an outdoor unit, the method comprising:
[0023] Sl, when the cooling load is calculated by the value of the cooling load and the value of time throughout the year, and the system partition and to determine the time of the year cooling load statistics
[0024] Still further, the specific operation of the cooling load value in step cooling load values and time throughout the year is:
[0025] The use of cooling load calculation software and annual hourly load calculation software were calculated for each room of the building cooling load value by the cooling load and annual values at each time.
[0026] The total cooling load and the value placed further condition determination system according to the room partition and system functions, home owners, pipe length, the outdoor unit, while the statistics for the ye...

The invention provides a method for selecting outdoor units of a multi-connected air-conditioning system, which includes the following steps: calculating the hourly air-conditioning cooling load value and the cooling load value at each time of the year, and determining the system partition and the annual cooling load time statistical table ; According to the total cooling load value of the system, select an optional outdoor unit selection scheme; determine the cooling capacity, power consumption and energy efficiency of these outdoor units under partial load conditions; According to the energy efficiency of the outdoor unit under partial load, determine the operation strategy of each outdoor unit selection scheme under partial load throughout the year; calculate the annual air conditioning energy consumption of each outdoor unit selection scheme. Choose the selection scheme with the lowest energy consumption as the best scheme for air conditioning system design. The invention proposes a new method for selecting the outdoor unit of a multi-connected air-conditioning system, which makes the multi-connected air-conditioning system more energy-saving.
Description
Technical field [0001] The present invention relates to the technical field of computer-aided calculation, in particular a new method for multi-line selection of outdoor air conditioning system. Background technique [0002] For years multi-split system air conditioner outdoor unit of selection, has not been great importance to designers, are based on the functional partitioning of the total air-conditioning cooling load value and the manufacturers of the device parameters, go directly to the selection, as long as the cooling capacity of the device parameters greater than or equal to the total cooling load. [0003] Various sizes capacity outdoor unit is not the same energy efficiency, particularly at part load, the conventional method of selection, this difference is not considered, so designed air conditioning systems with a plurality, most are not the most Energy saving. Inventive content [0004] The present invention addresses the above prior art drawbacks, proposed a techn...
