Description
Technical field
The present invention relates to the autocontrol method in a kind of air-conditioner field, particularly relate to the autocontrol method that a kind of chill temperature that can prevent that air conditioner room unit from directly discharging is spent low air-conditioner.
Background technology
Generally speaking, air-conditioner, indoor hot-air inspiration, cools off by heat exchange action in season at summer high temperature, again to indoor ejection, with this, regulates a kind of device of indoor air temperature.It constitutes refrigerant cycles by comprising with compressor, condenser, evaporimeter, expansion gear etc., generates cold air machine of using and the compositions such as circulation fan that discharge the cold air that generates.
According to this air-conditioner, the gaseous state condensing agent of low temperature, low pressure is compressed into HTHP under the compressor effect.HTHP gaseous state condensing agent after being compressed is through condenser, cool off condensing, become high-pressure liquid, then, through expansion gear [capillary 28], be transformed into the low-temp low-pressure abnormality, then, in evaporimeter, convert the gas form of low temperature, low pressure to, simultaneously, from around heat absorption, and the evaporimeter ambient air cooled off.Cooled air is arranged to the outside by circulation fan.Air-conditioner is regulated indoor air temperature with this process.
Air-conditioner is formed according to the machine configuration that constitutes refrigerant cycles, is divided into one-piece type substantially and two kinds of divergence types.Figure 1 shows that the separation type situation.It is indoor by being loaded on, the indoor set 10 that carries out the work of room air cool cycles be put in outdoor off-premises station 20 and separate to install and form.Indoor set is provided with evaporimeter 12 and circulation fan 14 for 10 li.20 li of off-premises stations are provided with the cooling fan 26 that condenser 22, compressor 24 and condenser are used.Indoor set 10 is connected by condensing agent pipe 30 with off-premises station 20.
The control method of above-mentioned air-conditioner is divided into two kinds of autocontrol method and hand operated control methods substantially.Automatic control method is that indoor temperature is set at particular value, then according to refrigeration room load situation, by the action of automatic control compressor 24 and circulation fan 14, guarantees that with this indoor temperature presses close to set particular value.And manual method then is the operation by the operator, simply controls the action of on/off with the circulation fan 14 that is attached thereto of compressor 24.
Here, above-mentioned automatic control method is divided into the simple control formula and two kinds of the variation control formulas that changes the use compressor that constant speed is used compressor again.
Above-mentioned simple control formula is benchmark with the design temperature, and when indoor temperature is lower than below the control range (being less than about 1 ℃), compressor is promptly shut down.When indoor temperature is higher than more than the control range (being approximately higher than 1 ℃), so, compressor is promptly reset.
According to this simple control mode, when cooling load was big, the rotating speed of circulation fan 14 accelerated, thereby the cold air drainage amount increases, and had to adapt to the characteristic that the refrigeration room changes fast.
On the contrary, above-mentioned variation control mode is used the compressor with variable of band commutation motor.In view of the above, can be subdivided into 5～6 sections to the condensing agent compression volume of compressor per unit hour again, therefore, can carry out the fine setting of temperature, reliablely and stablely the temperature in the holding chamber.
Autocontrol method according to above-mentioned air-conditioner, owing to only consider average cooling load according to the indoor whole space of design temperature decision, control duty, therefore, at the indoor set 10 with discharging cold air is the center, on the characteristic of diffusion low-temperature region, arrives the required standard temperature in the whole interior space, remove before the refrigeration room load, indoor set 10 will discharge strong cold air.
So, as adopt this conventional art, so, people before the refrigeration room load is removed, just become directly with cold air by force and have contacted when the indoor set 10, this state only otherwise finish will be felt stream of cold air near the personnel of indoor set 10, or feel that local skin has the temperature difference.Also can catch cold when serious, bring the variety of issue that is harmful to health.
