Description
본 고안은 공기조화기의 쾌적제어장치에 관한 것으로, 특히 보조증발기와 보조응축기의 역할을 각각 수행하는 보조열교환기를 이용하여 제습운전시 실내로 토출되는 공기의 온도를 높여 실내온도와 상대습도의 변동없이 쾌적한 실내공기조화를 수행할 수 있도록 한 공기조화기의 쾌적제어장치에 관한 것이다.The present invention relates to a comfort control device of an air conditioner, and in particular, by using an auxiliary heat exchanger that performs the role of an auxiliary evaporator and an auxiliary condenser, the temperature of the air discharged to the room during dehumidification operation is increased to change the indoor temperature and relative humidity. The present invention relates to a comfort control apparatus of an air conditioner capable of performing comfortable indoor air conditioning.
일반적으로 공기조화기는 제습운전시 실내공간으로 토출되는 조화공기는 온도가 매우 낮고 절대습도는 낮은 반면, 상대습도는 매우 높게 된다. 이와 같이 공기조화기의 제습운전이 토출되는 저온다습한 공기는 인체에 해로울 뿐만 아니라 사용자에게 불쾌감을 유발하는 요인이 되어 이를 해소하는 것이 요구되고 있는 실정이다.In general, the air conditioner is discharged to the indoor space during the dehumidification operation, the condition is very low temperature and low absolute humidity, while the relative humidity is very high. As described above, the low temperature and humid air discharged from the dehumidifying operation of the air conditioner is not only harmful to the human body but also causes discomfort to the user.
이를 감안하여 종래의 공기조화기에서는 제습운전시 실내로 토출되는 온도는 높이면서 효과적인 제습을 위해 실내팬의 회전수와 압축기의 운전주파수를 낮게 제어하여 왔으며, 정상운전시에는 압축기를 온,오프제어하여 운전능력을 조절하였다.In view of this, in the conventional air conditioner, the temperature discharged to the room during the dehumidification operation has been controlled while controlling the rotation speed of the indoor fan and the operating frequency of the compressor to lower the effective dehumidification. Driving ability was adjusted.
그러나, 종래의 공기조화기에서 압축기의 운전능력을 감소하고 실내팬의 회전수를 낮출 경우 제1도에 도시한 바와 같이 실내공기는 온도가 높고 상대습도가 낮은A에서 상대적으로 온도가 낮고 상대습도가 높은 B로 변화하게 된다. 이에 따라 실내온도를 유지하는 상태에서 습도를 낮추고자 하는 제습운전의 궁극적인 목적을 충실하게 달성할 수 없게 된다. 즉, 절대습도는 낮아지게 되지만 실내온도가 떨어지고 상대습도는 높아지게 되어 쾌적한 공기조화를 수행하기 어려운 문제점이 있었다.However, in the conventional air conditioner, when the operating capacity of the compressor is reduced and the number of revolutions of the indoor fan is lowered, as shown in FIG. 1, the indoor air has a relatively low temperature and a relative humidity at A having a high temperature and a low relative humidity. Will change to high B. Accordingly, it is impossible to faithfully achieve the ultimate purpose of the dehumidification operation to lower the humidity while maintaining the room temperature. In other words, the absolute humidity is lowered, but the indoor temperature is lowered and the relative humidity is higher, it is difficult to perform a comfortable air conditioning.
본 고안은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 냉방운전시 보조증발기의 역할을 수행하고 제습운전시 보조응축기의 역할을 수행하는 보조열교환기를 이용하여 실내온도와 상대습도의 변동없이 능률적으로 제습운전을 수행할 수 있도록 한 공기조화기의 쾌적제어장치를 제공함에 있다.The present invention has been made to solve the above problems, by using an auxiliary heat exchanger that performs the role of the auxiliary evaporator during the cooling operation and the role of the auxiliary condenser during the dehumidification operation efficiently without changing the room temperature and relative humidity The present invention provides a comfort control apparatus for an air conditioner capable of performing a dehumidification operation.

Accordingly, the high temperature and high pressure gas refrigerant discharged from the compressor 1 is condensed into liquid refrigerant by the condenser 2 and supplied to the first anisotropic valve V1 via the refrigerant pipe 3. The first relief valve V1 supplies the refrigerant condensed by the condenser 2 to the auxiliary heat exchanger 6. The auxiliary heat exchanger (6) receives the refrigerant condensed primarily by the condenser (2) and condenses it to the second capillary (4b).
