Knowing how dose direct expansion wshp and cooled water chiller using natural water at normal temperature as cooling source differ can help users better understand the two units and make better choice.
The water to air heat pump is a cooling and heating direct expansion air conditioning that uses natural water at normal temperature as its cooling and heating sources. Available cooling sources for water cooled chiller include natural water sources at normal temperature and cooling towers. Here we will analyze the difference between a direct expansion water source heat pump and a water cooled water chiller that uses natural water at normal temperature as the cooling source.
Different working modes
First, the two units have different working modes. The water source direct expansion unit is a heat pump heating air conditioning unit, which has heating and cooling working modes. However, the cooled water chiller is a single cooling unit and only has a cooling working mode.
Different unit output
Second, the two units have different output. The output of the water source direct expansion ac is cold air or hot air. The unit directly blows air into the room to achieve indoor space cooling or heating, and does not require a matching indoor terminal. On the contrary, the output of the cool water chiller is cold water. Therefore, if you want to use a water cooled chiller to achieve indoor cooling, you need to equip the unit with matching indoor terminals.
Different unit functions
Third, the functions of the two units are different. The output of a water source direct expansion system air conditioning is cold air or hot air, so the unit can only be used for indoor cooling and heating. The output of a water cooled water chiller is cold water, so this unit can be used to prepare cold water and can also be used for indoor space cooling.
In summary, the two units both uses natural water source at normal temperature as its source, but they are very different. Therefore, users who are considering using water source heat pump need to first determine your needs and preferences, and then choose the right unit based on these.
