Hi All,
I am working on the project of storage facility for one supermarket in Poland. In the file disposition is drawn the evaporator positions, door air curtain and the Underfloor heating pipes. At the moment I am developing the idea and I would like to listen to the different opinions.
On the floor above is a room in which two condensing units are stored. One unit is for regime of 0 °C and another one is for -18°C.
For the piping concept I would like to use headers.
The condensing unit room-units are stored in a room so I will propose to install one grill and above condensing units I would design one air duct for exhaust air. In this would be installed air to water heat exchanger which is connected to the buffer tank. The water from the buffer will be stored until the frost is likely to occur on the floor in two rooms. I have found some controller for the snow melting and de icing from Velta. This controller will control the pump and the 3 way valve.
Underfloor heating-will be used un two rooms. The pipes shall be connected to one manifold in the hallway. The floor sensor will be connected also to the actuators on the manifolds so that normally closed actuators shall open up when necessary.
Door air curtain will blow a recirculated air, without any conditioning, just to prevent infiltration.
What do you think about this stuff? The thing that worries me are condensing units,
Should I use for each evaporator a separate condensing unit or this thing will be OK? I thought to use a Bitzer condensing units with two pistons so that capacity could be changed and also the condensing fan speed control.
All the things that you think that i have missed oranything else, please comment
