The swimming pool has two categories: outdoor open-air swimming pool and indoor heated swimming pool . From the nature of the swimming pool, there are competition pools, training pools, diving pools, children's paddling pools, etc.; from the nature of business, there are public swimming pools, commercial hotel swimming pools, swimming pools in private villas, etc. However, no matter what type of swimming pool, there is a requirement to maintain a constant temperature of the pool water. The temperature of the pool water varies depending on the nature of the use. The heat loss of the swimming pool has the following aspects:
(1) The swimming pool water is evaporated due to the water surface, the water surface is transmitted, and the bottom of the pool and the wall of the pool are transmitted and the heat is continuously lost.
(2) Because people swimming in the swimming pool, they will lose some of the pool water, they must constantly replenish heat exchange, and the supplementary water needs to be heated, and it needs to be supplemented with some heat;
(3) In addition, the entire pool water treatment equipment and pipelines are constantly discharging heat to the surrounding environment.
The above-mentioned losses of heat need to be continuously supplemented in order to maintain a certain temperature in the pool water. These heat losses, combined with the heat load of swimming pool showers, etc., can be referred to as regular heat loads.
In addition, the constant temperature pool water has a new requirement for replacement at one time. In order to clean and disinfect, it is required to empty all the water in a certain period of time and re-enter warm water. If the supplemental water is cold water (water temperature is 5-15 ° C), then the heat required to heat the whole pool water is a one-time impact load.
Swimming pool water temperature
Generally, the indoor pool water temperature is 24-29 ° C, and the outdoor temperature is 22-30 ° C. If the indoor swimming pool has perfect air-conditioning heating facilities, it can be taken as 25 ° C; if the temperature is low, it can be taken as 27 ° C. The heat loss is related to the temperature of the pool water and also to the ambient temperature. Generally, the indoor ambient temperature is 1-2 ° C higher than the pool water temperature.
Kelanwater data indicates:
The best environmental parameters for an indoor pool are:
Air temperature 26-30 ° C
Pool water temperature 25-28 ° C
Ground temperature 30-32 ° C
Wind speed 0.05-0.1m/s
Relative humidity 50-60%
2. Indoor swimming pool relative humidity
It is necessary to maintain a certain relative humidity in the indoor swimming pool. When the outdoor temperature is -10 °C, the indoor air relative humidity is 50-60%, and when the heat transfer coefficient of the double-layer window is 2.9W/m2, the glass window will still be wet and dew; even if the outdoor temperature is -1 °C When the room is at 28 °C, it will also condense. Therefore, the swimming pool venue must be dehumidified.
The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel.
