Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam / cold water simultaneous production unit capable of producing steam for humidification and cold water for cooling simultaneously by using a heat pump.

[0002]

2. Description of the Related Art Conventionally, there is a heat pump chiller as one of the devices capable of simultaneously producing cold water for cooling, hot water for heating, or cold water for cooling and hot water for heating. The reason why the cold water and the hot water are manufactured at the same time is that there is a space that requires cooling throughout the year in addition to the cooling or heating, and one heat pump chiller is used for cooling and heating hot water. Both are manufactured at the same time.

On the other hand, humidification is carried out in order to prevent a decrease in humidity due to cooling or a drying due to heating. With today's humidification, measures against white powder associated with intelligentization are further added.
Further, it is required to improve the accuracy of relative humidity, and it is said that steam humidification has excellent properties in terms of humidification function. Generally, a humidifier for humidifying is often installed separately from the cooling / heating equipment.

[0004]

Conventionally, as described above, in many cases, the humidifier is installed separately from the cooling / heating equipment, and the cold water for cooling and the hot water for heating are provided. Although there are devices that can be manufactured at the same time, no unit has been found that can simultaneously manufacture steam for humidification and cold water for cooling. Therefore, the advent of a steam / cold water simultaneous production unit capable of simultaneously producing the steam for humidification and the cold water for cooling has been desired.

[0005]

In order to solve the above-mentioned problems, a steam / cold water simultaneous production unit according to the present invention has a unit body in which steam introduced water is used as a steam water treatment device and a heating heat exchanger. , A steam generator that heats through an auxiliary heat source heater and supplies as steam, and a cold water generator that cools the introduced water for cooling water through a cooling water treatment device and a cooling heat exchanger and supplies it as cold water. A heat exchanger for heating,
A heat pump for forming a refrigerating cycle by a heat exchanger for cooling, a compressor, and a throttle is provided.

[0006]

[Operation] The steam / cold water simultaneous production unit according to the present invention is
With the above-described structure, the steam water introduced into the steam generating unit is heated through the steam water treatment device, the heating heat exchanger, and the auxiliary heat source heater, and is supplied as humidifying steam. On the other hand, the cold water introduced into the cold water generation unit is cooled through a cooling water treatment device and a cooling heat exchanger, and is supplied as cooling cold water. During this time, in the heat pump, the high-temperature and high-pressure refrigerant gas compressed by the compressor radiates heat to the water for steam in the heat exchanger for heating, and by heating this water, it cools itself to liquefy and condense with the throttle. After expansion, it enters the cooling heat exchanger, where it absorbs heat from the cold water, and by cooling this water it evaporates by heating and becomes a gas that is compressed again by being sucked into the compressor. By repeating the cycle, the heating action of the steam water and the cooling action of the cold water are performed, and the energy is effectively utilized in the unit.

2 and a cooling heat exchanger 13 for cooling the treated water,
It comprises a cold water pipe 14 for supplying cooled cold water.

Further, the heat pump 4 comprises the above-mentioned heating heat exchanger 7 and cooling heat exchanger 13, a compressor 15, and
A throttle (expansion valve) 16 is connected by a refrigerant pipe 17 to form a refrigeration cycle.

The steam generator 2 and the cold water generator 3 absorb and radiate heat through the outside air when the heat absorption and heat dissipation balance of the heat pump 4 is lost. An endothermic blower 18 and a heat radiating blower 19 that blow outside air to the heat exchanger 13 are provided.

However, according to the above embodiment, the water pipe 5
The water introduced into the steam generating unit 2 by the steam processing unit 6 is processed by the steam water processing unit 6 and enters the heating heat exchanger 7, where it exchanges heat with the high-temperature and high-pressure refrigerant gas discharged from the compressor 15 of the heat pump 4. After that, the auxiliary heat source heater 9 is entered, and the auxiliary heat source heater 9 is heated again to generate steam in a steady state. This steam is supplied as steam for humidification to a required location through the steam pipe 10.

On the other hand, the water introduced into the cold water generating section 3 through the water pipe 11 is treated by the cooling water treatment unit 12 and enters the cooling heat exchanger 13, where the heating heat exchanger constituting the heat pump 4 is formed. It is condensed and liquefied in 7 and is cooled by exchanging heat with the refrigerant adiabatically expanded through the throttle 16. This cold water is supplied as cold water for cooling to a required location through the cold water pipe 14.

During this time, in the heat pump 4, the high-temperature and high-pressure refrigerant gas compressed by the compressor 15 radiates heat to steam water in the heating heat exchanger 7, and by heating this water, the heat pump 4 is cooled and condensed and liquefied. Then, after adiabatic expansion at the throttle 16, it enters the heat exchanger 13 for cooling, where it absorbs heat from the water for cold water, and by cooling this water, it evaporates and becomes gas, and the gas returns to the compressor 15 again. By being sucked and repeating this cycle, the heating action of the steam water and the cooling action of the cold water are performed.

The heat pump 4 has a heat absorbing action by cooling the cold water in the cooling heat exchanger 13 and a heat radiating action by heating the steam water in the heating heat exchanger 7.
Although the operation is performed while keeping energy balance, when the energy balance is lost, the heat absorption blower 18 or the heat radiation blower 19 that blows the outside air to the heating heat exchanger 7 or the cooling heat exchanger 13 on the insufficient side, respectively. Is operated and absorbs and radiates heat through the outside air to balance the heat.
