I work at a university and need to build an environmental test chamber 1mx1mx2m.
The chamber air temperature needs to be maintained between 18 and 24 deg. C. Outside temperature may be as high as 30 Dec C. The U value of the chamber insulation is 0.5.
A variable speed compressor cooling system is required to control this temperature closely (within 0.5 Dec C) and the compressor needs to have the ability to receive a control signal input for speed control.
Components inside the chamber may generate up to 7000kWhr per day.
The environmental control system is being built in-house and required design is only for the cooling system and covering all required components including the compressor and electronic interface module, the condenser, the expansion device and the evaporator plus all ancillary components such as connectors, fans, filters etc.
The design should include a list of components and recommended suppliers and cost estimate.
The project will be carried out in the UK.
