pool in the suburban area or in the house - the attribute of luxury comfortable life sought by many.And if the "Walrus" and simply people who love to harden, the temperature in the pool does not really matter, for all the rest is required to provide a comfortable temperature.For adults it is recommended water temperature is +23 ° C, and for children +25 - +28 ° C.In hot summer weather, the water in the pool itself is warmed to a temperature, but in the rest of the cooler months is necessary to ensure the pool water heating using special devices.In total there are several ways to heat water, which we describe below.
- retain heat - a special film for pools
- Solar Heated Water in the pool
- heating pool water via a heat pump
- exchanger for heating water in the pool
- Electric heaters for heating water in the pool
- fuel water heaters for swimming pools
retain heat - a special film for pools
Water - in itself a good heat accumulator.Therefo
as heat-saving cover film is used with bubbles of light color or black - for the accumulation of solar radiation.The film is cut out at the desired size and placed on the surface of the water without additional fastening.Such a coating reduces the evaporation of water from the surface and reduces heat transfer to air.
Solar Heated Water in the pool
The cheapest way to heat water - to use the sun's energy.This is especially true in areas dominated by clear sunny days.
To be effective, solar collector it should be located so that during the day it received the sun's rays 4 - 5 hours.This will keep the temperature of the pool water at the level of +25 - +30 ° C, or to raise the temperature of water at 6 - 10 ° C.
helio Solar water heating system in the basin consists of several elements: a solar collector, a pump for pumping water, filter and control valve.
Filter necessary in order that the solar collector is not got junk. pump needed to raise the water to the solar system and its promotion on it.Sometimes you want to install more powerful pump on the filtration system. control valve is needed for controlling the operation of the reservoir.How does it work?
on the surface of the solar collector are sensors that monitor the level of lighting and heat input.When the sensors detect that the collector receives a lot of heat, they instruct the control valve to direct flow of water from the basin to the manifold.This filtration system must be configured so that it was worked intensively during the period of the most active illumination.Then, the filtered water will flow into the solar collector, where it is heated and returned to the pool, on the other hand.
When the desired water temperature in the pool is reached, water is redirected and moves past the reservoir, just getting into the pool after the filtration.
inside solar collector circulating coolant, which is heated and the water of the pool.When in the dark collector cools down, the flow of water through it stops.Control valve closes it over the solar systems.
When installing solar collectors, there are certain rules:
- conventional solar collectors on the roof of a house, but you can install them on the ground, on a support, which provides a certain angle of inclination.
- desirable to have the collector array due south.It allowed them to offset no more than 45 ° to the south.
- Slope placement of solar panels depends on the setting of the region, so this information should be gleaned in the manual or consultant of the manufacturer.
- can install collectors on roofs that are deployed to the west and east.In this case, using special collectors with the increased area.
There are several types of solar collectors, you can see them in the diagram below.
collectors with vacuum glass tubes more expensive selective panels.A shop selling equipment for pools usually offer selective rectangular panel.
example, heating water in the frame pool by using panels "Sanhiter», «Azuro» and others.They are installed next to the pool on a special support, ensure the correct bias.
calculation of solar heating systems are best left to the professionals, because it takes into account many parameters: the intensity of solar radiation, the attendance of swimming pools, its size, place of installation, the required temperature in the pool.
The average surface area of the solar collector should be :
- to the indoor swimming pool or swimming pool in the house - 50 - 70% of the surface water.
- to the outdoor pool - 70 - 100% of the surface water.
care in solar pool heating systems are very simple.You only need to regularly clean the filters and drained for the winter.And many current models themselves poured water for the winter.In winter, the use of solar systems for heating water in the pool is not possible, because in our region a lot of snow.In the snow-free period vacuum collectors can operate in winter as antifreeze flowing in them, can withstand temperatures from -30 ° C to +70 ° C.
The most popular models of rectangular solar panels, but there are also pyramidal model and even awnings above the pool.Solar collectors in the form of a canopy over the pool perform two functions: to heat water and reduce water evaporation and heat transfer between water and air.Also, in addition to the heating by means of collector water is warmed by the action of direct solar radiation, which accumulates the black surface of the system.
heating pool water via a heat pump
second most economical way to heat the water in the pool can be regarded as use of the heat pump.His work does not depend on the intensity of solar radiation, the duration of daylight, enabling better quality control of water heating.
based heat pump put Carnot cycle.In fact, it works like a refrigerator, only in reverse.The heat pump takes heat from the environment and uses it to heat the water in the pool.The heat source may be soil, water or air.Use heat pumps with ground collector and water only for heating the pool is not profitable.Too expensive equipment itself and the installation of the collector.
Only in the case when home heating and other life support systems are organized via the heat pump with the ground or water collector, then it can be used to heat the water in the pool.
In other cases, use the swimming pool heat pumps air.Externally, they resemble the outdoor unit air conditioner.The fan sucks in ambient air, which transmits its heat to the coolant (antifreeze), which then passes the compressor and the evaporator.In the evaporator heated antifreeze its heat from the pool water, which comes to the pipes.Then the cooled heat transfer fluid is heated again and the cycle repeats.
Important!An air heat pump can operate even at ambient temperature +5 ° C.Usually it is set in the immediate vicinity of the street pool.If you need hot water indoor swimming pool in the house, the heat pump is installed outside the house.
Also note if the heat pump is used for air conditioning in the room, it can be easily used for water heating.The selected areas of the heat is directed to heat the pool, and not just thrown into the street.
heat pump for heating the pool is much more economical than a conventional electric heater.It consumes only 1 - 1.24 kW and produces heat by 5.5 - 6 kW, thereby saving up to 80% of electricity.This system is a great alternative to traditional energy sources, because it is completely harmless, does not harm the environment and saves.
Do not forget to keep warm in the pool with the help of a film with bubbles.After all, a lot more time and energy is spent on the initial heating of the water in the pool, and very little to maintain the desired temperature.
exchanger for heating water in the pool
heat exchanger is used quite often for heating water in the pool.It works as follows: it is connected to the heat source, such as heating boilers or inserted into the central heating system.The heating medium, heating in the boiler is sent to a heat exchanger where it gives off heat to the water from the pool, which is pumped therethrough.
heating system water in the pool works like this: the circulating pump connected to pump water through a heat exchanger.When the temperature of the pool water drops below the desired thermostat signals and the pump is activated.The water is pumped along the coil in the heat exchanger and is heated.Merges back into the pool on the other side.
Similarly, when the desired temperature is reached, the pump is switched off.Water from the pool is no longer to pass through the heat exchanger.
to a large swimming pool, several heat exchangers are used to speed up the heating water.The size and capacity of the heat exchangers are different from 13kVt to 120 kW.Also, they are horizontally and vertically, titanium and stainless steel.So you can pick up the unit for swimming pools of various sizes and dimensions.
The only drawback of this method of heating the water in the pool - this is dependent on the heating boiler.Although if you properly design the heating system and hot water, the heat exchanger can be used in this and in the summer, when the heating system is not working.The boiler will be activated only for heating the coolant, which circulates between the boiler and the heat exchanger of the pool.
Electric heaters for heating water in the pool
Flow heaters fitted inside the TAN, the water is not heated by a heat transfer medium, but directly from the heating element.This imposes certain restrictions on water quality.It should be soft enough, not pure salt to the heating element will last longer and is not covered with scale.Also heater is made of alloy, corrosion-resistant and covered with several layers of protection.
Given that energy consumption with this method of heating is quite large, usually only use electric heaters to heat a small pool.For example, inflatable pool, brick pool, small jacuzzi pools.
Inflatable swimming pool with water heated using an electric heater - a luxury not available even a family on a budget.
electric heater for the pool is directly connected to the network.Its capacity is varying from 3 to 18 kW.Sometimes household current is not able to provide such a device work.This is a significant drawback.
fuel water heaters for swimming pools
Finally I would like to dwell on this method of heating water, the use of fuel boilers.For example, the boiler can be a gas, pyrolysis, with wood, fuel oil and other fuels.The water is heated in it can be implemented in several ways:
- C by a heat exchanger, the boiler heats the coolant, and only heats the water coolant in the pool.
- Line hot water directly into the pot.
- heating water in the tank, and then reset it to the pool.
Typically, these systems heat water in the pool is used in areas where there is no mains gas, as well as other convenient ways to heat the pool.Installation of any boiler is connected with a number of difficulties: authorization, projects, calculations, chimneys and ensuring fire safety.All this needs to be addressed before the construction of the pool, and sometimes at home.
When selecting hot water in the basin need to take into account its size, the amount of water to a temperature to be heated, whether you want to process automation, and more.Budget - is also an important aspect.Therefore it will be more correct if the selection and installation of heating equipment will be handled by experts.
