Abstract

PURPOSE:To make it possible to perform a comfortable heating operation and which has a small heat loss by a method wherein a condenser and an evaporator in a cooling cycle are provided in the room and the upper part of the room is cooled while the lower part of the room is heated by utilizing warm air in the upper part of the room. CONSTITUTION:An electromagnetic valve 10 is opened to cause a burner 20 to operate and an electromagnetic valve 17 is also opened. A coolant is heated to vaporize by a coolant heater 13, the vaporized coolant is sucked into, and discharged from, a compressor 14 to reach a second heat exchanger 7 and a first heat exchanger 5 and by operating blowers 6 and 8, the room is heated. When the temperature in the upper part of the room reaches a predetermined value, the electromagnetic valve 10 is closed and the combustion of the burner 20 is stopped. As a choking resistor is inserted in the coolant, the second heat exchanger acts as a condenser and the first heat exchanger 5 acts as an evaporator. In this case, an air blast by a blower 6 is directed upward in the room 2 and that by a blower 8 is directed downward so that the temperature distribution in the room is substantially equalized.

Description

[Detailed description of the invention] This invention relates to a heating system.

Conventionally, indoor heating using a refrigeration cycle involves installing a condenser in the indoor unit, which is connected to an outdoor unit equipped with a compressor, evaporator, and throttling resistor. They transported the patient to the hospital and tried to warm up the room.

However, the temperature distribution in the room during heating is not limited to heating using this refrigeration cycle /1/, as shown in Figure 1, the closer to the floor the lower the temperature, and the closer to the ceiling the higher the temperature. However, when you are in a living space, you feel uncomfortable because your head is hot and your feet are cold.

This invention has been made in view of the above points, and an object of the present invention is to provide a heating method that is comfortable and has little heat loss by using warm air in the upper part of the room to cool the upper part of the room and heat the lower part of the room. The purpose is to

Hereinafter, one embodiment of the present invention will be described with reference to Figs. 2 to 4. In the figures, (1) is an indoor unit disposed in the upper part of the chamber (2), and each is installed independently in the outer cylinder (3). The air passages (4'a) and (4b) are formed in such a way that one of the air passages (4a) is heated by using the temperature in the upper part of the heated room (2).
The first heat exchanger (5
) and a blower (6) that blows the air passing through this 1st f @ exchanger upwards into the room (2).
) is provided with a second heat exchanger (7) that acts as a condenser during heat utilization operation, and a blower (8) that blows air passing through the second heat exchanger downward into the chamber (2). The first heat exchanger (5) and the second heat exchanger are connected via a throttle resistor (9) and an electromagnetic valve αG disposed in parallel with the throttle resistor that is closed only during heat utilization operation. 0υ is an outdoor unit that is connected to the indoor unit (1) through the pipe body a2 and is installed outdoors, and includes a refrigerant heater θ and a compressor 0 as a heat exchanger that heats the cold during heating operation. Outdoor heat exchanger θG, which is a condenser for air conditioning, and throttle resistance part OQ, which forms the pressure difference during cooling.
are sequentially connected, and a bypass circuit OFj having a solenoid valve Oη is connected to both ends of the series circuit of the outdoor heat exchanger 09 and the throttle resistor αQ so that the refrigerant bypasses during heating.
An end of the refrigerant heating Rg 03 is connected to the first heat exchanger (5), and an end of the throttle resistor Of9 and the bypass circuit 010 is connected to the second heat exchanger (7). 0 Samurai is an outdoor blower for condensation, and (A) is a burner that heats the refrigerant heater 01.

To explain the entire operation of the device configured as described above, first, when the temperature in the room (2) is low and heating is to be performed (hereinafter referred to as heating), the solenoid valve θO is turned on (a).
and open it, burn the burner, and open the solenoid valve 07).
Also opens with ONj. As a result, the refrigerant is heated and evaporated by the refrigerant heater o1 as shown by the broken line, becoming a high-temperature, high-pressure gas refrigerant, which is sucked into and discharged from the compressor θ, and passes through the bypass circuit 0 to the second heat exchanger (7). It passes through the solenoid valve 00 to the first heat exchanger (5), heats the first and second heat exchangers, and operates the blower (6) (8) to heat the room. The indoor temperature distribution at this time is as shown in Fig. 1 as in the conventional case, but when the temperature in the upper part of the room rises to a predetermined temperature, this is detected and the operation is switched to heat utilization operation. That is, when the temperature in the upper part of the room reaches a predetermined temperature, this is detected by a detection element (not shown), and the solenoid valve 00 is turned off and closed, thereby stopping combustion in the burner rod. As a result, the refrigerant flows as shown by the dashed line, and since the throttle resistor (9) is inserted, the second heat exchanger (7) acts as a condenser, and the first heat exchanger (5) acts as an evaporator. . This is followed by a blower (6
) and the blower (8) are in full operation, and the temperature distribution in the room is controlled by directing the air from the blower (6) upwards into the room (2), and by directing the air from the blower (8) downwards into the room (2). As shown in Figure 5, the temperature is almost uniform, and the amount of heat from the temperature difference (hatched area in the diagram) is used effectively, and there is no discomfort in the living space, and it also saves labor. Become. On the other hand, during cooling, the solenoid valve M is turned on and opened, the combustion of the burner blade is turned off, and the solenoid valve θ7) is turned off and closed. As a result, the refrigerant flows as shown by the solid line, the outdoor heat exchanger QQ acts as a condenser, the first (5) and second heat exchanger (7) act as evaporators, and the refrigerant (61 ( 8
)'f: The inside of the room (2) is cooled by operation.

In the above embodiment, a refrigerant heater is installed in the same circuit to heat the room during heating, but the same effect can be obtained even if the heating is performed using a heat pump method. A similar effect can be obtained even if a heating device such as the above is installed separately in the room and is linked to the heating device.

As described above, the present invention is provided with a condenser and an evaporator of a refrigeration cycle indoors, and air heated by the condenser is blown downward into the room, and air cooled by the evaporator is sent upward into the room. By blowing air to
It also has the effect of providing heating with less heat loss7.
