Description

Apparatus for preheating of heat-source air in air heat-source heat pump}

The present invention relates to a preheating device for a heat source air of an air heat source heat pump in a heating system using a heat pump. More specifically, when the outside temperature falls below 0 ° C., the heat medium, which is a heat source in the heat source supply, is moved forward to the evaporator of the heat pump. Continues to circulate through the fin coil type heat exchanger to the heat source supply to preheat and pass the outside temperature to the evaporator, thereby minimizing frost on the evaporator even if the outside temperature drops below 0 ℃. The present invention relates to a heat source air preheating device of an air heat source heat pump capable of minimizing defrosting of a pump.

In general, heating facilities that require heating, such as buildings or facility houses, are heated directly or indirectly using a heat pump. The heat pump includes a water heat exchange method and an air heat exchange method according to the heat exchange method of the condenser and the evaporator, but a suitable one is used depending on the intended use.

When the heat pump is a heat exchange method, when the heat pump is operated, condensation heat is dissipated from the condenser. Thus, when the heat of condensation is dissipated from the condenser, air is passed through the heat exchanger while guiding the heated air to the duct. When the heat pump is a water heat exchange method, the heat pump passes water through the heat medium to the condenser and heats it while the heat medium passes.Then, the heated heat medium is guided to the circulation pipe to radiate heat from the radiator inside the heating facility. The heating facility to be heated is heated.

The heating medium can be heated directly from the condenser of the heat pump to the heating facility, but the heat storage tank can be installed in the middle of the circulation pipe, and the heat storage medium is temporarily stored in the heat storage tank. The heating medium in the tank can be circulated and heated.

In addition, as mentioned above, the heat pump is mentioned only for the case where the heat exchange method and the water heat exchange method are provided, respectively, but a combination of the heat exchange method and the water heat exchange method is also used.

As described above, the heat pump includes a compressor, a condenser, an expansion valve, and an evaporator connected through a refrigerant circulation line to form a cycle. When the heat pump operates, the heat pump is compressed into a gas refrigerant of high temperature and high pressure as the compressor operates. The compressed refrigerant is condensed into a condenser and condensed into a liquid refrigerant having a high temperature and high pressure while being heated around the condenser by heat exchange (heat dissipation) while the refrigerant passes through the condenser.

The liquid refrigerant of the condensed high temperature and high pressure is evaporated in the evaporator as it is in a low pressure state in the expansion valve, and as the refrigerant evaporates (evaporates) in the evaporator, the vaporization heat of the refrigerant necessary for evaporation is absorbed from the outside so that the surroundings of the evaporator are cooled. The low temperature and low pressure gas refrigerant passing through the evaporator is compressed by suction by a compressor, thereby allowing continuous heat exchange in the evaporator while repeatedly performing the aforementioned process.

As described above, when the heat pump is operated, since the temperature of the outside air (outside air) that is sucked for heat exchange with the evaporator is high during the day or summer, the heat of vaporization necessary for vaporizing the refrigerant of the evaporator is sufficient. If the outside air temperature (below 5 ℃) is low during winter nights on this coming day, there is a lack of heat of vaporization necessary to vaporize the refrigerant in the evaporator from the outside air sucked for heat exchange with the evaporator. .

As the frost starts to form, the frost is accelerated more rapidly. As the frost forms on the evaporator, the heat exchange efficiency is further lowered because it blocks the air flow of the evaporator and obstructs air flow.

When frost is generated in the evaporator as described above, the heat pump is operated in reverse cycle to remove the frost of the evaporator, or the heat pump is stopped and defrosted by a separate heater.

However, in the conventional air heat source heat pump as described above, when the frost is removed by using a separate heater, the heat pump should be operated in a state where the operation of the heat pump is stopped. There was no problem.

In addition, in the case of a heat pump having a four-way valve, the evaporator acts as a condenser in the heat pump to dissolve and remove the frost of the evaporator, so that the condenser of the heat pump forming one cycle should perform the evaporator role. Because of this, since the heat of evaporation must be absorbed from the heating facility that requires heating, there is a problem in that a cold air flows to adversely effect the cooling.

The present invention has been researched and developed in order to solve the conventional problems as described above, the purpose is to provide a fin-coil type heat exchanger in the evaporator of the heat pump provided on the inflow of air in front of the evaporator and the heat source to the heat exchanger If the outside air temperature falls below 0 ° C, the heating medium is supplied to the heat source supply through the fin coil type heat exchanger provided at the evaporator of the heat pump. This preheats and passes the outside air temperature, which prevents the occurrence of frost on the evaporator even when the outside air temperature falls below 0 ° C. Also, it preheats the heat source air of the heat source heat pump to minimize the defrosting operation of the heat pump. To provide.

Another object of the present invention is to obtain the effect of widening the heat transfer area of the evaporator by integrating or connecting the fins of the heat exchanger with the fins of the evaporator, in addition to the radiant heat received from the outside air can also be received as conductive heat transferred directly from the heat exchanger. To provide a heat source air preheating device of an air heat source heat pump to maximize the heat exchange efficiency.

Another object of the present invention is to provide a heat source supply unit for supplying the heat medium to the heat exchanger as a hydrothermal tank or a geothermal heat exchanger that can store the waste heat as well as the excess heat of the house can be sufficiently preheated and passed through the outside air introduced into the evaporator This provides a preheating device for the heat source air of an air heat source heat pump that minimizes defrosting in the evaporator even when the outside air temperature drops below 0 ° C and minimizes defrosting of the heat pump.

The evaporator 14 is provided with a fin coil-type heat exchanger 40 at the front of the evaporator 14, i.e., the air inlet 14b of the case 14a, which is a position before contact with the air introduced therein for heat exchange. The heat exchanger 40 has a heat medium circulation line 41 having a heat medium supply pump 42 so as to circulate the heat medium as a heat source, and a heat source supply unit 50 at the end of the heat medium circulation line 41. ) Is provided.

In addition, there is a geothermal heat exchanger that obtains a heat source by circulating heat medium that exchanges heat with underground air, ground water and underground soil.

It will be described a process of operating the heat source air preheating device of the air heat source heat pump according to the present invention configured as described above.

First, when the heat pump is operated, the refrigerant compressed by the compressor 11 is circulated from the compressor 11 to the expansion valve 13, the evaporator 14, and the compressor 11 through the condenser 12. When the heat pump 10 is operated as described above, the compressor 11 is operated to compress the gas refrigerant at a high temperature and high pressure, and the compressed refrigerant is pumped to the condenser 12, and the heat is transmitted while the refrigerant passes through the condenser 12. The condensation is condensed into a liquid refrigerant having a high temperature and high pressure while being warmed around the condenser 12 by heat exchange.

The liquid refrigerant of the high temperature and high pressure condensed as described above is transformed into a low pressure state in the expansion valve 13 to be evaporated in the evaporator 14. As the refrigerant evaporates (evaporates) in the evaporator 14, the heat of vaporization of the refrigerant required for vaporization is removed. Absorption from the outside causes the surroundings of the evaporator 14 to be cooled.

The low temperature and low pressure gas refrigerant passing through the evaporator 14 is sucked and compressed by the compressor 11 so that a continuous heat exchange is performed in the evaporator 14 while repeatedly performing the above-described process.

Thus, while the heat pump is operating, the condenser 12 dissipates high heat. At this time, since the convective pump 22 of the heat medium line 21 is operated, the heat medium in the heat storage tank 20 is continuously circulated, thereby storing the heat storage tank 20. Heat is accumulated and stored in the heat medium of 50 ~ 60 ℃.

In this state, when the heating pump 32 of the heating line 31 is also operated, the heat medium in the heat storage tank 20 is circulated to the heat storage tank 20 through the heating line 31 and the radiator 33. Since the radiator 33 in the facility 30 dissipates the heat possessed by the heat medium, the heating facility 30 is heated.

During the heating as described above, the evaporator 14 is discharged through the blower 14c through the evaporator 14, the outside air introduced from the air inlet 14b by the blower 14c. At this time, since the refrigerant of the evaporator 14 absorbs the vaporization heat of the refrigerant required for evaporation (vaporization) from the outside air, the surroundings of the evaporator 14 are cooled.

When the evaporator 14 is operated as described above, when the temperature of the external air flowing into the evaporator 14 becomes less than 0 ° C., the heat medium supply pump 42 on the heat medium circulation line 41 is operated, thereby causing the heat source supply ( Since the heat medium of 50 is supplied and circulated, the external air is preheated while passing through the heat exchanger 40 before entering the air inlet 14b of the case 14a, and then passes through the evaporator 14. The external air preheated by the radiant heat of the heat exchanger 40 as well as the heat of the heat exchanger 40 is conducted to pass through the evaporator 14, thereby providing sufficient vaporization heat required by the evaporator 14, thereby No frost is produced in the evaporator 14.

6 to 10 are views showing another embodiment of the heat source supply in the heat source air preheater of the present invention.

6 is provided with a heat source supply tank 51 capable of basically storing and supplying heat medium water to the heat source supply device 50, and the water supply tank 51 collects rainwater falling on the roof of the heating facility 30. Except that the rain line 30b is connected to guide the drip tray 30a and the rainwater collected in the drip tray 30a to the water heat supply tank 51, and the same configuration as the present invention.

According to the heat source air preheating device of another embodiment configured as described above, when the outside temperature is 0 ° C. or lower when the heat pump 10 is operated, air is supplied to the evaporator 14 by circulating the heat medium in the water heat supply tank 51. After preheating, the vaporization (evaporation) heat required by the evaporator 14 can be sufficiently supplied while passing through the evaporator 14 to prevent frost (frost) from being generated on the surface of the evaporator 14.

When the rain pump is rained while using the heat pump 10, the rainwater flowing down from the roof of the heating facility 30 is received through the drip tray 30a and guided through the rainwater line 30b to be stored in the water supply tank 51. Can use sensible heat as a heat source.

7 is a heat supply tank 51, which is one of the heat source supply units 50 of one embodiment to recover the excess heat to be ventilated or cooled due to the temperature of the heating facility is increased by the radiant heat of daytime sunlight, and the heating The line 31 is connected to the excess heat recovery line 52.

According to the heat source air preheating device of another embodiment configured as described above, the house which is the heating facility 30 has a rapid rise in temperature in the heating facility 30 due to the radiant heat of daytime sunlight, and thus the heat medium of the water heat supply tank 51. It is higher than the temperature.

In this case, when only the heating circulation pump 32 of the heating line 31 is operated, the heat medium of the hydrothermal supply tank 51 is circulated through the excess heat recovery line 52, the heating line 31, and the radiator 33. At the heat exchange in 33, the heat absorbed in the heating facility 30 is absorbed, and the heat medium temperature in the water heat supply tank 51 is warmed up.

In this way, the excess heat of the heating facility 30 is stored in the hydrothermal supply tank 51 and when the outside air temperature drops, the thermal medium supply pump 42 of the thermal medium circulation line 41 is operated to heat the thermal medium in the hydrothermal supply tank 51. Supply circulation to the heat exchanger 40 along the heat medium circulation line (41).

The auxiliary heater 53 is a hot water production boiler, electric heater, geothermal heat exchanger and the like.

According to the heat source air preheating apparatus of another embodiment configured as described above, when the heat medium temperature of the water heat supply tank 51 is lowered, the auxiliary heater 53 is operated to maintain the heat medium of the water heat supply tank 51 at a constant temperature. It is.

Therefore, when the outside air temperature flowing into the evaporator 14 of the heat pump 10 falls below a predetermined temperature, the heat medium supply pump 42 of the heat medium circulation line 41 is activated to heat the heat medium in the hydrothermal supply tank 51. Supply circulation along the line 41 to the heat exchanger 40.

In this way, since the air flowing into the evaporator 14 by the heat exchanger 40 is preheated and then supplied to the evaporator 14, vaporization (evaporation) heat required by the evaporator 14 is passed while passing through the evaporator 14. It can supply enough, and it prevents the formation of frost (frost) on the surface of the evaporator 14.

9 is provided at the end of the heat medium circulation line 41 connected to the water heat supply tank 51 so as to prevent corrosion by debris and sea salt when the heat source stored in the water heat supply tank 51 is misfolded or seawater. The heat exchanger 54 is provided, and FIG. 10 is connected to the end of the heat medium circulation line 41 and the heat medium line 21 so that hot water, which is a heat medium of the heat storage tank 20, can utilize the heat source of the heat exchanger.
