Problems solved by technology
[0011] However, in an air-conditioning system in which an electric heater is installed inside the casing of the indoor unit, there is a risk of fire and the like because the heating element (electric heater) generates heat indoors.
In particular, when the indoor unit is a ceiling-buried type, the danger of fire is very high, and there is also a problem that its maintenance is also complicated.
[0012] In addition, the air conditioning system with a burner installed in the outdoor unit must use fuel (gas or oil) other than electricity, and because it uses fire directly, there is a problem that there are too many requirements for safety devices and exhaust devices.

Embodiment Construction
[0022] Hereinafter, a preferred embodiment of the present invention will be described in detail according to the accompanying drawings.
[0023] The air conditioning system to which the heat pump circuit of the present invention is applicable, such as figure 1 As shown, since the refrigerant flow direction is reversible, two operations of cooling and heating can be performed, so there is an outdoor unit A arranged on the outdoor side and an indoor unit B arranged on the indoor side.
[0024] The outdoor unit A is equipped with a compressor 2 that sucks and compresses low-pressure refrigerant and discharges it in a high-temperature and high-pressure state, a heat exchanger 1 that uses a fan 5 to exchange heat with outside air, and an expansion device 4 that depressurizes the condensed refrigerant . In addition, the indoor unit B is equipped with a heat exchanger 6 for exchanging heat with indoor air, and a fan 7 for forcedly blowing the heat-exchanged air into the indoor space...

An air conditioning system with a refrigerant heating apparatus is provided to improve efficiency of a heating cycle safely and effectively by improving a heating apparatus for heating a refrigerant supplied to a heat exchanger of an indoor unit from a compressor, in a heating operation mode. An air conditioning system has a heating apparatus for heating a refrigerant before the refrigerant discharged from a compressor disposed to the outside is supplied to an indoor heat exchanger functioning as a condenser, in a heating operation mode. The heating apparatus includes a heating device with plural heaters to heat a refrigerant flowing in a refrigerant line; a driving unit controlling driving of the heaters; and a control unit controlling the driving unit so that one of the heaters is on within a predetermined temperature range and one of the heaters is off for the initial or finial time of the temperature range. Thus, temperature is precisely controlled and the life span of the heaters is lengthened.
Description
technical field [0001] The present invention relates to an air-conditioning system applicable to a heat pump circuit, and in more detail, relates to an air-conditioning system equipped with a refrigerant heating device, which is used to supply the heat discharged from the compressor to the indoor heat exchanger during the heating operation. The refrigerant is heated, thereby improving the efficiency of the heating circuit. Background technique [0002] Generally, an air conditioning system to which a heat pump cycle is applied is designed to switch the direction of refrigerant flow through a four-way valve in summer and winter to perform both cooling and heating with one unit. [0003] Such a conventional air-conditioning system applicable to a heat pump circuit includes: an outdoor unit with a built-in compressor that drives a drive motor to compress refrigerant into high temperature and high pressure; and an indoor unit connected to the outdoor unit in a closed circuit and...
