Frameless installations

Бескаркасные установки VC бассейнового исполнения

Frameless VC installations of pool design

Modern installations for swimming pools are considered one of the most technologically complex and responsible devices in the formation of the microclimate. Competently to design and make similar installation it is possible only at harmonious work of highly qualified personnel, beginning from design engineers and finishing assemblers. Without a doubt, there are a lot of leaders in this direction at the moment and almost all of their work is positioned as a standard equipment layout. Moreover, in most solutions, energy efficiency is not fully used.

This mainly concerns the moment when the condenser of the heat machine is installed at the outlet. In addition, in such installations often use the reverse, which makes it impossible to get the work of the thermal unit for the entire capacity calculated by the project, or initially put such a machine with an excessive capacity.

The task of forming an optimal microclimate in the pool can be solved using innovative approaches. It is a question of installations where there are no reversible heat engines as the reverse does not give the chance to apply fully both dehumidification, and to recover leaving heat.

If there is no ventilation, or incorrectly calculated, the safety of the structure and the entire finish of the pool, as well as the comfort of staying in it, is a big question. Moisture evaporation from the water surface leads to an increase in air humidity. If moisture surpluses are not removed in a timely manner, then condensation forms on the walls, Windows and ceiling of the room, in turn provoking the appearance of fungus, mold and stagnant unpleasant odor. In addition, it causes corrosion on metal parts and gradually destroys building structures.

With excessive humidity, people feel uncomfortable: it is difficult for them to breathe and extremely uncomfortable to be indoors. The same unpleasant sensation can lead to incorrectly selected temperature regime of air and water, draft and lack of air exchange. All this leads to air stuffiness and the formation of unpleasant odors, which entails poor health and a desire to leave the room as soon as possible.

In order to avoid such troubles in the room with the pool should be supported by the following air parameters:

  • air humidity should be 50-65%;
  • the water temperature should be at least +24-26 degrees Celsius at an air temperature of 26-28 degrees;
  • the level of air exchange is calculated as 80m < sup>3< / sup> per person;
  • air mobility in the so-called working area should be less than 0.2 m/s;
  • free chlorine in the air above the water mirror must be at a concentration of less than 0.1 mg.

Frameless VC medical installations

The air in the premises, which are subject to high hygienic requirements, for example, microchip Assembly plants or clinics and hospitals, despite the difficult conditions (pollution by dust, microorganisms, suspended particles) must meet the highest standards of quality. That is why the requirements for the design and individual components of the air conditioner operating in conditions of high sterility are really high.

VDI 6022 And VDI 3803-standards adopted by the Union of German engineers

– standard VDI6022 establishes the basic principles of these requirements. And especially important points are the issues of hygiene and cleaning of installations.

– DIN 1946-4 is responsible for the air hygiene of the premises. This standard specifies special requirements for installations that provide ventilation of hospital premises.

The scope of application of hygienic units is quite wide. They are used in the case of special requirements for the quality of air purification: in medical institutions, in pharmacological and chemical production, in operating rooms, in the food industry, the so-called “clean production”, in health resorts, medical institutions for children, sports rehabilitation centers and so on. In addition, ventilation units of hygienic performance can be put in residential facilities for public and personal use: theaters, cottages, sports centers, recreation areas and so on.

Condensing units and chillers

Компрессорно-конденсаторные блоки NORDET

NORD ET condensing units

KKB-compressor and condenser units-are used for condensation (deposition) of vaporous refrigerant, as well as its supply to the heat exchanger of the evaporative unit of the air conditioner. In most cases, KKB is used to interact with the freon heat exchangers standing inside the typesetting and monoblock devices. Such heat exchangers are responsible for cooling the air that enters the room from the street. That is, KKB performs two tasks at once – not only ensuring the flow of fresh air into the room, but also its cooling.

The main units of this unit are: condenser-heat exchanger of the air conditioner, compressor, receiver (storage), separator, which plays the role of liquid separator, elements of the automated control system of the air conditioner and safety valves. Compressor-condenser units are used in ducted, precision and Central air conditioners, as well as split-system air conditioners.

The principle of interaction of the compressor-condenser unit and supply units is based on the fact that the air collected by the fan of the ventilation system from the street passes through a cooled heat exchanger, in turn cooled by freon. The latter enters it under the pressure of the compressor through copper tubes, and then boils from the heated street air and passes from a liquid state to a gaseous one. Then it returns back to the compressor-condenser unit, where it is again cooled in the KKB heat exchanger due to air fan cooling and goes into a liquid state, again rushing to the heat exchanger with further repetition of the entire cycle.

all condensing units are divided into 2 categories:

  • 1-Vaya-it includes specialized devices that are manufactured on the basis of chillers (this name is the compressor-condenser units with water cooling);
  • 2-Paradise are ordinary external blocks standing in powerful split systems. We are talking about compressor-condenser units with air cooling.

Here the principle of operation< / strong> is similar to the principle of operation of external units of split systems and is based on the Carnot cycle. At the initial stage, the working body of the air conditioner, i.e. freon, under the influence of the heat of the air from the room evaporates in the indoor unit. Due to the tightness of the system, freon, passed into a gaseous state, is under increasing pressure. After its evaporation, it ends up in the outdoor unit, where the pressure becomes even higher due to the operation of the compressor. This leads to an increase in the gas condensation temperature and, as a result, an increase in the efficiency of the entire system as a whole. When condensation freon gives heat to the environment around, and then again enters the indoor unit, but in the form of a liquid, and then the above described cycle is repeated.

In split systems, which are capable of not only cooling but also heating the air, the compressor is able to move the gas in the opposite direction – when switching the system to the heating function, direct evaporation will be carried out in the outdoor unit, and its condensation – in the internal.

among the advantages of such KKB is to highlight:

  • ease of installation;
  • low price;
  • possibility to install units indoors, if there is no suitable site on the street, or it is impossible to mount the unit on the roof.

The disadvantage of such units can be called only one: it is a power limitation, when compared with compressor-condenser units having water cooling.

MISTRAL chillers

Chiller Classifications

Chillers have a number of classifications. One of them is by the type of circulating fluid. Thus, water has the maximum efficiency as a circulating liquid. However, the technological processes carried out, as well as the requirements imposed on temperatures, allow the use of other types of liquids: alcohols, oils, glycol. And in this regard, today emit absorption and freon chillers.

Absorption refrigeration units are more appropriate For large facilities because they save energy, resulting in reduced overall resource consumption. The role of freon in such units is performed by water and lithium bromide.

Due to the design differences, chillers can be classified into refrigeration units that have a remote condenser and have a built-in device.

The Separation of chillers can be carried out on such parameters as the presence of a heat pump, the connection diagram, the type of cooling of the condenser. According to the last parameter chillers are divided into devices with water and air cooling. Water-cooled devices also differ in the number of refrigerant circuits.

Roof fans

The roof fans produced by the company are radial fans of one-way suction and low pressure, whose working blades are bent back. The body of the products are made of carbon steel with a polymer coating of the highest quality. The deflector around the body is designed to protect the ventilation channel from rain and dust. 3-phase asynchronous electric motor of the air series is used as a drive.

The function of overheating protection in the fans of the “TERRAL” series is realized with the help of built-in thermal sensors with terminals for connecting a device that provides protection for the engine.

Production of roof fans is made of carbon steel. They are used in exhaust ventilation systems and mounted on the roofs of public and industrial buildings. Fans can work both in the ventilation network, and do without it. Their purpose-the movement of non-explosive gaseous media, whose temperature is not more than 80°C, with a content of solid impurities not more than 0.1 g / m3, but without fibrous materials and sticky substances, in the ambient temperature range from -30°C to +40°C.

Reduced power consumption due to increased efficiency: thanks to the use of the impeller with the blades bent back, the fan is characterized by two major advantages: this impeller provides it with optimal efficiency and increased resistance to contamination.

Built-in control switch: its presence greatly simplifies the process of electrical connection.

Fire damper

Fire prevention valves are devices designed specifically to block supply and exhaust ventilation ducts in order to prevent the spread of fire in the event of a sudden fire. In addition, they are responsible for the admission of fresh air to the hearth fire, and the timely removal of smoke and other combustion products.

Structurally, the fire-prevention valve consists of a housing, inside of which a movable damper is placed, and a drive responsible for the transfer of the damper from the initial position to the working one.

Fire-prevention valves manufactured by the company, based on the functional purpose and scope of use, are divided into:

  • smoke valves;
  • fire-retaining valves;
  • double acting valves;
  • normally closed (NC) valves.

In fact, the smoke valve and the valve NZ — the same thing, and they differ only in the field of application.

Огнезадерживающий клапан (нормально-открытый)

Fire-retaining valve (normally open)

The fire-retaining fire-prevention valve (normally-open) represents the fire-prevention valve, whose flap in an initial state stays in open position. It is intended for closing the ducts, and thereby blocking the spread of flame and products of combustion. In the standard mode of operation of the ventilation system, such valves do not create obstacles for the passage of air through the sections of the vent ducts where they are installed. If suddenly a fire starts, the valve onesidezero valve will immediately shut it down bore and thereby prevent the spread of flame through the air ducts, and, in addition, will not support combustion oxygen from fresh air that would do to the fires.
Клапан дымоудаления (нормально-закрытый)

Smoke exhaust valve (normally closed)

The smoke removal valve (fire-fighting smoke, normally-closed) is a fire-fighting valve, whose damper in its initial state is in the closed position (NZ – normally-closed). It is used to open vent channels, through which smoke is removed. In the standard operating mode of the ventilation system, such valves cover certain areas of the vent ducts where they are installed (for example, openings in the smoke removal shaft, available on stairwells). If a fire suddenly starts, the flap of the smoke valve will be opened, which will make it possible to quickly remove smoke from places of evacuation of people (for example, staircases) and other areas that are smoky.
Клапан двойного действия (универсальный)

Double acting valve (universal)

Valve double action (also called the fire valve, universal) is a fire valve closing at the beginning of a fire, thereby preventing fire propagation through air ducts and fresh air to the fire sudden fire. Once the fire is extinguished, the valve dual action is opened, providing an opportunity for the rapid removal of smoke and other combustion products.

Literally every fire-fighting valve (including fire-retaining valve, universal valve and smoke removal valve) has its own set limit of fire resistance.
