Anti -urbeting valves in heat pump installations play a key role in protecting the system against damage caused by the freezing of the medium. They are an essential element for the correct and trouble -free operation of the installation, especially in the case of a break in power supply in the power grid. This article discusses the details of the structure, operation and installation of anti -urbel valves from the perspective of the heat pump installer.
Operation of anti -urbel valves
Anti -urban valves and In heat pump installations, they begin to work when the ambient temperature drops below 0 ° C. When lowering the temperature to -3 ° C, the valve opens, enabling the outflow of the medium, which prevents its freezing. The valve operation is proportional to the temperature drop - the lower the temperature, the greater the outflow of the factor. When the temperature reaches 4 ° C, the valve closes, which eliminates the need for additional consumption of the medium, minimizing losses. The anti -I and IW, which is in the Dambat offer, are intended for installation in installations using monoblock heat pumps. Their task is to eliminate the risk of thickening and freezing the factor in the installation at negative temperatures, which may occur, e.g. as a result of a power failure. Why is the role of the anti -urbeting valve to the heat pump so important? Well, in the event of freezing the medium, the resulting ice can damage the heat exchanger or other elements of the installation, and the costs of repair will be very high in such a situation.
So although anti -urbet valves are relatively small elements with a not very complicated design, their role is huge. Therefore, it is simply not profitable to give up the assembly of this element, the cost of which is very small compared to the expenses that would have to be incurred in the event of damage to the installation.
Construction of anti -zamoration valves
Anti -Żezamroving valves available in Dambat's offer are simple in construction, but incredibly effective in operation. They consist of a three -hearted structure, including the body, insert and a stop valve. The body made of brass ensures high durability and corrosion resistance, which guarantees the longevity of the valve operation. Thanks to the modular construction, valves and can be quickly and easily replaced, which is an important advantage for installers.
The importance of correct assembly
Installation of anti -urbel valves is a simple but key process for their effectiveness. It is recommended to install the valves on both the power supply and the return of the heat exchanger. It is important to mount them in places most exposed to low temperatures, but avoiding the closeness of heat sources that could disturb their proper operation. The correct installation in a vertical position with outlet directed down allows for optimal medium discharge. Importantly - anzamroxation valves for heat pump work only when temperature changes, ensuring reliable and tight cut. They do not affect the pressure and remove only the minimum amount of water required to prevent possible damage as a result of freezing the medium.
The anti -chamflower valves offered by Dambat can be replaced quickly and easily, which is enabled by their three -part construction, with a stop valve placed between the body and the insert. The body itself, as well as the thermal element of the valves and are made of brass.
Variants and parameters of anti -urban valves
Anti -urbeting valves are available in three basic variants, differing in diameter of connections: 1ʺ, 1ʺ and 1½ʺ. The maximum flows of these valves are 166.7 l/min, 266.7 l/min and 416.7 l/min, respectively. The maximum drain in each variant is 16.7 l/min, which is sufficient to protect the system against freezing. The scope of work (medium) is 0ºC -65ºC, and the operating range (external temperature) is in the range -30ºC -65ºC. The valve is fully opened at 1ºC, and the closing temperature (medium) is 4ºC. The maximum pressure is 8 bar.
Installation recommendations
Anti -illegal valves should be mounted with intervals: both among themselves and from the ground. The horizontal distance between the valves should be 15 cm, while the vertical distance of the lower part of the valve from the ground must also be at least 15 cm. Proper distribution of valves will ensure effective medium discharge at the time of temperature drops, thus guaranteeing optimal protection of the installation.
