As such, only with the expanded gas separating device including one high pressure pump and a sealed tank, its application is possible in both a high pressure (8-10 kg/cm^2) cooling and heating system for a high-rise building and a low pressure (3-6 kg/cm^2) cooling and heating system for a low-rise building, and thus, the present invention is capable of considerably improving the marketability and compatibility of the expanded gas separating device as well as maximizing the convenience of installation and applicability in a field by eliminating confusion caused by the classification of high pressure and lower pressure systems.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-

The present invention maintains the pressure of the cooling / heating water flowing along the piping of the cooling / heating system at a predetermined level so as to prevent the leakage of water through the connection portion of the piping and the damage of the piping, And more particularly to an inflatable gas separation device equipped with various heating and cooling systems to form a circulating circuit for separating an inflating gas component (particularly, an oxygen component) or a foreign substance (particularly, a chloride)

Generally, in a residential space such as a house or a working space such as an office or a factory, the cooling of the summer and the heating of the winter are emerging as factors of the main living environment. Recently, Due to the increase in the number of sites and offices, the demand for energy for heating and cooling is increasing rapidly.

In keeping with this trend, facilities such as hospitals, hotels, and schools, including large apartment complexes and buildings, can be integrated and effectively used for heating and cooling the residential space or work space using a single, economical heat source such as a heat pump Centralized heating and cooling system is installed and used.

In the centralized heating / cooling system, the cooling / heating water produced by electric energy or fossil energy is first introduced into the distributor through the main pump from one large heat source device, and then the air / And the circulation method of collecting the used cooling / heating water by the recovering device and supplying the water to the heat source device is applied.

In the cooling / heating system as described above, the pressure of the cooling / heating water flowing along the piping is maintained at a predetermined level to prevent the leakage of water through the connection portion of the piping and the damage of the piping, while the corrosion and scale of the piping Scale) is separated from the cooling / heating water is installed and used together with the cooling / heating system.

When the temperature of the cooling / heating water circulating inside the closed piping of the cooling / heating system is increased and the cooling / heating water expands and the internal pressure of the system is increased, the expansion gas separator as described above may be provided with an expansion tube having a relief valve Cooling water is supplied to the expansion tank to remove the expanded pressure and gas components, and when the temperature of the cooling and heating water is lowered and the internal pressure of the system is lowered, the cooling and heating water stored in the expansion tank as supplementary water is supplied to the system And performs a function of increasing the piping pressure of the system again by pressurizing and pumping with the piping.

Since the open-type inflatable gas separation device has a shape in which the expansion tank is opened, the installation cost is low and the supply of the make-up water is easy, while the inflation tank (Cooling / heating water) stored in the expansion tank is increased, and in addition, the energy loss due to the evaporation of the supplemental water (cooling / heating water) stored in the expansion tank is increased, There is a concern that there is a risk of freezing of the expansion tank, and that the installation place of the expansion tank must be the uppermost side of the piping system.

As a representative example of the closed inflation gas separation apparatus for solving the problem of the open-type inflatable gas separation device as described above, the present invention is applied to a gas-liquid separator of the present invention, which is disclosed in Patent Application No. 5345 filed by the present applicant in 2000 and registered as a patent (No. 10-0370603) And an inflation gas separator for heating and cooling systems, which was filed by the present applicant in 2007 Patent Application No. 104997 and registered as a patent (No. 10-0798503).

The inflation gas separating apparatus proposed by the present applicant is made of a sealed tank capable of disassembling and assembling the expansion tank, and according to the pressure difference method by the relief valve, the cooling / heating water inside the piping for the cooling / heating system passes through the expansion pipe So that the gas component and the foreign substances contained in the cooling / heating water are separated and discharged from the inside of the expansion tank, and at the same time, the supplementary water stored in the expansion tank can be supplied again to the cooling / heating system side by using the pressure maintenance pump It is.

A water level sensor for sensing the level of the replenishing water and supplying water to the expansion tank along the water supply pipe is installed in the expansion tank. An overflow pipe is provided on the upper side of the expansion tank. A drain pipe for discharging foreign matter (sediment) is provided on the lower side, a vacuum break valve for controlling the degree of vacuum in the tank to a stable level, and a gas component separated from the cooling and heating water are provided on the upper cover side of the expansion tank, And a gas removal valve for automatically discharging the gas to the outside of the expansion tank.

As described above, in the inflation gas separation apparatus of the present applicant, since the piston principle according to the increase / decrease of the water level of the makeup water, that is, the water level of the makeup water is lowered and the degree of vacuum inside the expansion tank increases, the solubility of the cooling / When the water level of the makeup water is increased and the internal pressure of the expansion tank is increased, the gas component separated from the cooling / heating water is discharged through the gas elimination valve, so that the gas components and foreign substances contained in the cooling / So that it can be separated and discharged.

However, in the prior-art expansion gas separating apparatus, the pressure maintenance pump is divided into a high-pressure pump and a low-pressure pump, and the relief valve of the expansion pipe is also divided into a high-pressure relief valve and a low-pressure relief valve, produced the two products for a low pressure separately, then there is a high pressure (8 ~ 10kg / cm 2) heating and cooling systems, such as high-rise building application is plant the high-pressure-only expansion gas separator and a low pressure (3 to as a low-rise building 6kg / cm 2 ) In the place where the heating and cooling system is applied, there was a trouble such as installing a low pressure exclusive inflation gas separation device.

In other words, it is necessary to precisely distinguish the high pressure dedicated inflation gas separation device and the low pressure exclusive inflation gas separation device in accordance with the type of the heating and cooling system applied to the field, but the appearance of the inflation gas separation device including the expansion tank is almost the same In the case where a low-pressure low-temperature air-conditioning system for a building and a high-pressure air-conditioning system for a high-floor system are mixed in a single building, two inflation gas separation systems must be applied. There is a problem in that not only the external competitiveness is lowered due to the rise but also the spatial restriction is increased due to the installation of the inflating gas separator.

Particularly, through the structural improvement of applying the pressure reducing valve 18 to the low-pressure supply pipe 4a, an inflation gas separator (not shown) having one pressure maintaining pump 17 as a high-pressure pump and one sealed tank 1 10) can be changed to the high-pressure heating / cooling system 14 or the low-pressure heating / cooling system 15 or used simultaneously, thereby reducing the number of pumps to a minimum, thereby lowering the cost, installation volume and weight of the product. It is possible to easily switch to and use the spare pump 5 when the pressure maintenance pump 17 fails.
