Description

TECHNICAL FIELD [0001] The present invention relates to a multi-heat source multi-heat pump system having an air heat source, a multi-heat source multi-heat pump system, Source Cooling and Heating Simultaneous Operation, Water Heat Source Heating and Cooling Simultaneous Operation}

The present invention uses four types of operation modes based on heat storage base, cooling base, air heat source base and hydrothermal source while using the air heat source of outdoor side and the water heat source of indoor side as separate type, Each base mode can be selectively switched among each other, and automatic switching is possible using the four sides and the electronic valve in each base of the thermal storage alone, thermal storage alone, thermal storage cooldown, simultaneous thermal storage and defrost operation modes. Cooling water is supplied from the evaporator to the cooling load by using the air heat source and the water heat source as the heat source of the heat pump and at the same time, Heat source multi-heat pump that recovers the waste heat from the waste heat and uses it as hot water.

In general, thermal energy is obtained by burning a combustible material or by using electricity, chemical action, or reaction.

The methods of obtaining thermal energy by such combustion, action and reaction are such that the obtained heat energy is stored in a heat storage device or converted into a usable state and then used as a means for drying, cooling, heating or heating. There is a problem of generation and emission of environmental pollutants due to combustion of combustible materials, together with the necessity of a device for combusting combustible materials, since materials must be prepared and burned to obtain heat energy.

The method of obtaining the thermal energy by the electrical and chemical action is significantly less pollutant production than the method of burning the combustible material. However, since it requires a substance or apparatus for reaction, when it is desired to obtain a large amount of heat energy There is a problem in that the volume of the device is increased and the device for the device is complicated and bloated due to the necessity of safety, and there is a problem that the thermal energy to be obtained is smaller than the volume of the facility.

An outdoor heat source and an air heat source heat pump are known to solve the above problems.

The heat pump absorbs heat in the air and compresses it in the compressor to generate a high temperature compressed gas including the shaft force to raise the temperature of the water or to heat the heat exchanged condensation heat to the atmosphere. Is the same as the refrigeration cycle using the evaporation heat, and is constituted by the reverse cycle using the condensation heat in the high temperature maintenance.

In general, heating facilities requiring heating such as houses are directly or indirectly carried out using a heat pump. The heat pump has a water heat exchange system and an air heat source exchange system according to the heat exchange method of the evaporator.

In the case where the heat pump is an air heat source exchange type, when the air heat source heat pump is operated, when the refrigerant is evaporated under low temperature and low pressure using the sensible heat of the air in the heat source evaporator, air is passed, And when the heat pump is a water heat exchange type, the water that is a heating medium is passed through the evaporator, the water is heat exchanged while the heating medium passes through the condenser, and the evaporated refrigerant is guided to the compressor. Which is located in the condenser, to heat the heating equipment to be heated.

Although the above-mentioned heat pump is referred to only when the air heat source exchange method and the water heat exchange method are respectively provided, the air heat source exchange method and the water heat exchange method may be used in combination.

The air heat source heat pump as described above includes a compressor, a condenser, an expansion valve, and an air heat source evaporator connected through a refrigerant circulation line to form a cycle. When the air heat source heat pump is operated, The refrigerant compressed in the high pressure gas refrigerant is compressed by the condenser and condensed into the high temperature and high pressure liquid refrigerant while the refrigerant circulates through the condenser to heat the refrigerant and heat the condenser.

As the refrigerant evaporates (vaporizes) in the air heat source evaporator, the heat of vaporization of the refrigerant necessary for vaporization is absorbed from the outside, so that the air heat source The gas refrigerant of low temperature and low pressure that has passed through the air heat source evaporator is sucked and compressed by the compressor so that continuous heat exchange is performed in the air heat source evaporator during the above- .

As described above, when the air heat source heat pump is operated, the refrigerant temperature of the air heat source evaporator is taken up from the outside air (external air) sucked for heat exchange with the air heat source evaporator to rise (about 5 캜) The refrigerant is sucked into the compressor and compressed into a gas refrigerant of high temperature and high pressure. When the air temperature is lower than 5 캜, the refrigerant can not be vaporized into a complete gas and it is sucked into the liquid refrigerant in a particle state such as mist. .
