Embodiment Construction

[0015] Referring to the accompanying drawings, the abscissa in the figure is the outdoor air temperature change axis, tw represents the outdoor air temperature in °C; the ordinate in the figure is the indoor air conditioner temperature change axis, tn represents the indoor air conditioner temperature in °C.

[0016] According to the difference of outdoor temperature, the indoor air temperature of the air-conditioned environment adopts different design and operating values, and the main adjustment steps are as follows:

[0017] ①When the outdoor air temperature is 23-25°C, set the indoor air conditioner temperature to 25°C;

[0018] ②When the outdoor air temperature is 25-35°C, set the indoor air-conditioning temperature tn=25+0.3*(tw-25);

[0019] ③When the outdoor air temperature is higher than 35°C, set the indoor air-conditioning temperature to 28°C;

[0020] ④When the outdoor air temperature is 7--12°C, set the indoor air-conditioning temperature tn=22-0.21*(7-tw);

Abstract

The invention provides an energy saving adjusting method of a central air conditioning system which relates to the air conditioning system technical field in civil architecture. The method of the invention comprises the following steps that: 1) when the outdoor air temperature is between 23 to 25 DEG C, the indoor temperature of the air conditioner is set to 25 DEG C; 2) when the outdoor air temperature is between 25 and 35DEG C, the indoor temperature of the air conditioner is set to tn=25+0.3x(tw-25), wherein, tw is the outdoor air temperature;3)when the outdoor air temperature is above 35 DEG C, the indoor temperature of the air conditioner is set to 28 DEG C; 4) when the outdoor air temperature is between 7 and 12 DEG C, the indoor temperature of the air conditioner is set to tn=22-0.21x(7-tw); 5) when the outdoor air temperature is 12DEG C below zero, the indoor temperature of the air conditioner is set to18 DEG C. Compared with the prior, the method of the invention can efficiently reduce the operation consumption of the central air conditioning systems, improve human sense of comfort and efficiently avoid the occurrence of air conditioning sickness.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning systems for civil buildings, in particular to an adjustment method for energy-saving operation of the central air-conditioning system. Background technique [0002] At present, the design and operation of the central air-conditioning system of civil buildings is to keep the indoor air temperature of the air-conditioned environment constant. For example, in summer, the indoor air temperature is always kept constant at 24-28°C. The building takes a high value; in winter, the indoor air temperature is always kept at 18-22°C, among which the high-end civil buildings take a high value, and the middle and low-end civil buildings take a low value. This kind of central air-conditioning system often leads to a large temperature difference between indoor and outdoor, and the operation consumes a lot of energy. At the same time, in summer, because the human body stays in an air-conditioned ...
