HVAC Design for Warehouse

HVAC design will need lot more data.

You need to know height of the warehouse apart from the area, temperature required in the warehouse vs outside temperature, warehouse construction details like whether the roof and walls are insulated to know heat load, occupancy in the warehouse, any addtional heat load like machines, lighting etc need to be detailed.

Are you serious? You are making a proposal and you have no clue why!

Dear M-A,

You clearly do not know the first thing about this topic and therefore should not attempt to proceed any further in this vein. Find a competent HVAC consultant preferrably one who can demonstrate a track record of successful projects in the field of pharmaceutical and associated laboratory work and brief him/her.

You will save yourself a lot of time and money.

I would also implement Demand Controlled Ventilation (co2 sensors) with one central location reporting the data to a BMS. Please feel free to contact me for further info. Greg 631-756-9116 x129

Hi Greg,

I would question the VfM aspect of a CO2 monitoring system in a large and usually sparsely populated space such as a warehouse. Trickle ventilation with purging when ambient conditions permit is probably as far as you need to go. It is possible that the CO2 based control is valid in a lecture theatre environment, but given the extra kit needed and the on-going costs of servicing I would not be rushing to accept such an addition to the control philosophy.

Energy saving from correctly sizing of fans, motor drives and ductwork will pay dividends in the long run, apply the KISS principle whenever possible. Fancy gizmos invariably fall by the wayside over time and cannot be justified in most instances.

Good luck,

Massey.

That's true in a warehouse setting.. Maybe just C0 monitoring.. Massey,you seem to know about DCV. Have you implemented this in the past??. If so, contact me for further info gshine@cemtrex.com

Dear Z-A,

Please cut the CAPS LOCK! Shouting at people is not done.

Your 'solution' is short on logic. Do you realise that your chiller will have an electrical demand of 350 kW under favourable conditions.Until ambient conditions are presented you cannot even predict the likely COP of the set-up. By the time you have added in all the extras you will be selecting a 500kW machine! What about the AHU side? There is no reference to the volume of air needed to transmit this degree of 'coolth' into the environment.

What you are suggesting is a glutton for energy and I would not wish to burden a client with this sort of operating costs until all other options had been tested.

Anyway back to basics; as you (we) do not know the volume of the store it is impossible to proceed cogently.

Presumably somewhere along the line there are Building Regs to satisfy and we do not know anything about the proposed type of construction, so heat gains/losses are quite fictitious.

This is not an 'on the cheap' design exercise. I am a professional engineer with over 40 years experience in this field and will not be taking this matter any further.

See my initial comment regarding the appropriate way forward.
