It relates to a variable heat pump cooling and heating device combined with a heat recovery ventilator.

      As interest in overall quality of life increases, interest in indoor air quality, which is spent most of the day, is also increasing. The Ministry of Environment has enacted indoor air quality management laws such as multi-use facilities to provide indoor air quality standards and maintain indoor air quality. As a mandatory installation of ventilation equipment, the necessary ventilation amount according to the use should be provided for multi-use facilities.

      Airless and muddy indoor air is the main culprit of our health, and people live more than 90% indoors. For various reasons, pollutants are constantly generated, which can harm the health of indoor air. There is an urgent need for ventilation.

      In particular, new buildings have good airtightness, which can reduce heat loss by about 25% -50%, but the natural ventilation rate is lowered. Therefore, these buildings need an economical and effective mechanical ventilation system to discharge indoor air pollutants and excess moisture, as well as external fresh air supply.

      However, in general, ventilation reduces the cooling and heating effect, but if not, indoor air is polluted.

      When ventilated, the indoor temperature is lost to the outside air, causing a cold or hot feeling of discomfort due to a sudden change in temperature, and an increase in the load of the air conditioner, resulting in excessive economic loss of precious energy. Provides fresh air to the room by crossing the outdoor air and discharges the polluted air to the outside to purify the indoor air, while simultaneously recovering heat (energy) and recovering heat (energy) while maintaining the indoor temperature. As a result, a heat recovery ventilation system has been introduced to minimize the energy consumption of air conditioners.

      In addition, the air conditioner is operated when the indoor temperature decreases or rises due to the temperature difference caused by the introduced outdoor air. In general, the air conditioning system and the ventilation system complement the heat pump air-conditioning system and the total heat exchange heat recovery ventilation system capable of separate systems or air-conditioning.

      Hereinafter, embodiments of each operation mode of the air conditioning and ventilation system according to seasonal indoor and outdoor temperature conditions will be described in detail with reference to the accompanying drawings.

       Example 1. Cooling and heating mode (see Fig. 2)

      The air supply bypass line B1 for bypassing the outside air to the heat pump cooling / heating circuit P and the exhaust bypass line B2 for bypassing the indoor air are linked.

      When the outdoor temperature is above 5 ℃ (no optimum temperature for heating) and below 37 ℃ during cooling, it is an operation cycle of a circuit configuration that performs only cooling and heating without ventilation, and heat recovery is performed in the same configuration as a normal air heat source heat pump operation cycle. The air is supplied to the air supply heat exchanger 20b and the exhaust heat exchanger 20a via the air supply bypass line B1 and the exhaust bypass line B2, and the air is discharged by heat exchange.

      For example, when implementing a heat pump heating cycle, the high-temperature, high-pressure gas fruit (refrigerant) generated by the compressor 10 is converted into a liquid refrigerant after supplying heat to the indoor air in the condenser, and the low-temperature, Heat pump heating is performed by implementing a circulation cycle sent to the compressor at a low pressure gas state. At this time, the air supply heat exchanger 20b operates as a condenser, and the exhaust heat exchanger 20a operates as an evaporator. The cycle operates in opposition to the heating cycle by reversing the refrigerant flow by redirecting the four-way valve 12.

      In addition, the ventilation operation is supplied to the air supply inlet 90c by opening the opening control motor 50a on the air supply bypass line B1 formed between the air supply inlet 90c and the air exhaust outlet 90a in the compressor 10 operating state. The outside air is heat-exchanged with the exhaust heat exchanger 20a and then exhausted to the outside through the exhaust outlet 90a, and the indoor air is also opened between the exhaust inlet port 90b and the air supply outlet port 90d. Opening the control motor 50b to implement the heat recovery ventilation cycles to return the air supply heat exchanger 20b back to the room through the diesel air supply outlet 90d, respectively, to replenish heat to the heat pump air-conditioning system and to reduce energy by reducing heating and cooling loads. While contributing to this, it is possible to easily match the set room temperature.

Example 2. Ventilation Mode (See FIG. 3)
The circuit configuration is connected to the bypass line B3 for refluxing part of the outside air supplied by heat exchange in the air supply line A1, the exhaust line A2, and the air supply line A1.

    The compressor is a simple ventilation mode that does not operate, that is, does not perform heating and cooling. The air supply fan 40b and the exhaust fan 40a on the air supply line A1 and the exhaust line A2 operate to perform only ventilation, but indoors. If the outside air temperature supplied is too low to cause discomfort in the room, the bypass fan is opened by opening the opening control motor 50c on the bypass bypass line B3 which is bypassed and refluxed in the middle of the air supply line A1 for supplying air. When the operation 40c operates, the heat recovery heat exchanger 30 absorbs heat from the indoor air to replenish the heat amount of the refluxed air, thereby performing a ventilation process of supplying the outside air of an appropriate temperature to the room. (Operates reversely when cooling)

Example 3 HVAC and Ventilation Modes (see FIG. 4)
The air supply line (A1), the exhaust line (A2), the air supply bypass line (B1) for bypassing the incoming outside air and the exhaust bypass line (B2) for bypassing the indoor air are connected to the heat pump cooling and heating circuit (P). It is a circuit configuration that performs air conditioning and heating.

      As an operation mode with good load responsiveness, since both heating and cooling operations of Example 1 and Example 2 can be performed simultaneously,

      The opening degree of the opening degree control motor 50a and the exhaust bypass line B2 opening degree control motor 50b on the air supply bypass line B1 is adjusted according to the ventilation amount, and is heat-exchanged in the air supply line A1 to supply the indoor air. The air supply reflux cycle in the bypass bypass line (B3) for recirculating some of them is not implemented, while maintaining a comfortable room temperature while significantly reducing ventilation and heating and cooling loads.

Example 4. Heating and cooling bypass (BY-PASS) mode (see Figure 5)
The heat pump air-conditioning circuit P is connected to the air supply line A1 and the exhaust line A2, and a bypass bypass line B3 for refluxing the external air supplied by heat exchange, thereby implementing a double overlapping heat recovery heat exchange cycle. Configuration.

      This operating mode is a basic heat recovery heat exchange cycle when the exhaust exhaust temperature is below 5 ° C or 37 ° C or more during cooling and heating, and in addition to the bypass control motor 50c and bypass fan for bypass bypass in the bypass bypass line (B3). By operating the air supply reflux heat exchange cycle for circulating the sensible heat exchanger 30 again via the driving of the 40c, the operation mode is to increase the exhaust emission temperature by supplementing the heat amount of the exhaust heat by implementing the overlapping heat recovery heat exchange cycle of the double.

      For example, when the exhaust discharge temperature is 8 ° C. or lower during heating, frost is generated in the exhaust heat exchanger 20b. When frost occurs, the heating heat and performance of the heat pump is significantly reduced, so defrosting operation is performed. During heating operation, the heating heat can not be supplied. Therefore, the exhaust gas is maintained at 5 ℃ or higher by operating in the cooling and heating bypass mode. It is possible to suppress the occurrence of frost in the exhaust heat exchanger (20a) during the main surface heating.

      That is, when the exhaust discharge temperature is 5 ° C. or lower, the bypass fan 40c of the bypass bypass line B3 is operated. When the opening degree of the bypass opening control motor 50c is adjusted and opened, the sensible heat / electric heat exchanger At 30, the outside air heat-exchanged with the indoor warm air is partially introduced into the air supply heat exchanger 20b, and at the same time, the air is partially introduced into the heat recovery heat exchanger 30 to exchange heat with the air introduced from the room again, and the air supply temperature Since the air flowing from the room loses less heat, it is possible to maintain the exhaust exhaust temperature above 5 ° C, eliminating the occurrence of frost, and responding to condensation and freezing phenomenon flexibly and actively. In total, independent operation of heating and cooling operation and ventilation operation is possible separately, and simultaneous operation is possible by combining cooling and heating ventilation operation.

     Therefore, by controlling the flow path of the indoor and outdoor air and controlling the operating speed of the air supply fan and the exhaust fan, it is possible to implement the improved ventilation efficiency by adding or subtracting the amount of outdoor air supplied and the amount of indoor air exhausted.
