作を行なうのである。In other words, the refrigerant flows to the compressor a, the four-way valve that switches between cooling and heating operation, the indoor heat exchanger C that becomes a condenser during heating and the evaporator during cooling, the floor radiator e, and the floor radiator e during cooling operation. In order to prevent this, a reverse 11-valve (g) provided on two pages, a pressure reducing device, and an outdoor heat exchanger (i) that serves as an evaporator during heating and a condenser during cooling are connected in a ring, and are connected to a floor radiator (e) during heating operation. A refrigeration cycle is constructed by connecting a check valve f provided for flowing refrigerant to a floor radiator e and a check valve g in parallel. Furthermore, an indoor blower d is attached to the indoor heat exchanger C, and an outdoor blower j is attached to the outdoor heat exchanger i. The operation during heating operation is as shown by the solid line arrow in the figure. The refrigerant is compressed to high temperature and high pressure by the compressor a, passes through the four-way valve, radiates heat in the indoor heat exchanger C and the floor radiator e, and condenses. The air then passes through check valve g, is reduced in pressure by a pressure reducing device, becomes low temperature and low pressure, is evaporated in outdoor heat exchanger i, passes through four-way valve again, and returns to compressor a.

せず冷媒温度も低い。However, when using a heat pump type floor heating system such as the one mentioned above, by operating the indoor fan d during heating operation to supply warm air into the room, and using it in conjunction with the original floor heating to obtain a heating effect from the warm air. The following problems arise. According to the refrigeration cycle diagram shown in Figure 4, indoor heat exchanger C and floor radiator 3B and 3E are connected in series, so the refrigerant sent from compressor A radiates heat between them. . However, the floor radiator e has a large heat capacity and takes about one hour to warm up itself. Therefore, at the start of operation, the high pressure does not rise much and the refrigerant temperature is low.

た。When indoor fan d is operated in this state, the time course of the blowing air temperature is as shown by the dotted line k in Figure 4, and it takes time for the blowing air temperature to reach a temperature that provides a comfortable feeling of heating. . Note that floor heating is originally radiant heating, so you can get a comfortable feeling of heating without raising the room temperature like hot air heating. Therefore, since the capacity of the compressor B can be reduced, the compressor B used can be smaller than a normal heat pump type air conditioner. This heat pump type floor heating system has the function of hot air heating,
When using both together, a compressor with a smaller capacity than a normal heat pump type air conditioner is used, so especially when the outside temperature is low, due to the nature of the heat pump shown in Figure 3,
There were various problems in that the capacity was lowered and cold air was blown out without being able to obtain warm air at the start of operation, causing discomfort to the delicious food.

ている。In Figure 1, its configuration is: a compressor 1, a four-way valve 2 that switches between cooling and heating operations, an indoor heat exchanger 3 that serves as a condenser during heating and an evaporator during cooling, a floor radiator 4, and a floor radiator 4 for cooling. A check valve 5 provided to prevent refrigerant from flowing to the radiator 4, a pressure reducing device 6, and an outdoor heat exchanger 7 that serves as an evaporator during heating and a condenser during cooling are connected in an annular manner. A refrigeration cycle is constructed by connecting a check valve 8 provided for flowing refrigerant to the vessel 4 in parallel to the floor radiator 4 and the check valve 6. Further, the indoor unit (not shown) provided with the indoor heat exchanger 3 is provided with an indoor blower 9 and an electric heater 1o, and an outdoor blower 11 is provided opposite to the outdoor heat exchanger 7. There is.

An electric heater 1° and an indoor blower 9 are connected to these contacts 16a and 16b, respectively, and the wires are connected as a whole as shown in FIG.

う動作を行なうのである。In the above configuration, when performing heating operation, power switch 1
2 is turned on, and at the same time, the cooling/heating changeover switch 13 is turned on to the contact side. This causes the compressor 1, four-way valve 2, and outdoor blower 11 to operate. As a result, the refrigerant flows as shown by solid arrows in FIG. That is, the refrigerant compressed to high temperature and high pressure by the compressor 1 passes through the four-way valve 2, radiates heat in the indoor heat exchanger 3 and the floor air gap g4, condenses, passes through the check valve 6, and is depressurized. It is depressurized in the device 6 to a low temperature and low pressure, evaporated in the outdoor heat exchanger 7, and returned to the compressor 1 after passing through the four-way valve 2'ff.

きる。At the start of the heating operation, the manual switch 15 is turned on when the outside temperature is low and it is necessary to obtain a heating effect immediately. As a result, the timer 16 is activated and the contacts 16a, 16
b is closed and the indoor blower 4 and electric heater are operated to supply hot air into the room, and heating is performed by using the function of hot air heating in addition to the original floor heating. In this case, the time course of the blowout air temperature is shown in the solid line in Figure 4, and the time it takes to reach the blowout air temperature that provides a comfortable feeling of heating can be shortened to about 1/3 of the conventional time, and the outside temperature is low. The impact of this can be significantly reduced. Furthermore, since the circuit is created to link the electric heater 1o with the indoor blower 9, there is no need to forget to turn on or turn off the electric heater 10, making operation easier and completely preventing cold air from blowing out. can.
