Detailed introduction

Key points of selection of air cooled chiller:

1. Cooling capacity (cooling load) : according to the heating heat of the equipment matching the corresponding cooling capacity (KW), the law of energy conservation: system sensible heat Q1+ latent heat Q2+ installed efficiency and pipe insulation and cold loss;

I, Compressor selection:

1. Compressor evaporation temperature: the refrigerant evaporates and absorbs heat in the evaporator (lower than the water outlet temperature of 5℃) (for example, the process needs 10℃ water outlet, the compressor evaporation temperature selection is lower than 5℃). The material form of the radiator is determined according to the use requirements;

2, Condensing temperature: the cooling and condensing temperature in the condenser of the refrigeration unit (ambient temperature +15℃ to 20℃), the air cooling unit is generally greater than 50℃ (because in summer or when the outdoor ambient temperature is high, the cooling area of the condenser can ensure the efficient and reliable operation of the unit), and the heat transfer area of the cooling equipment must be enough;

3, compressor refrigerant type selection: environmental protection R134A,R410, R407, R744, R1270

4. Compressor brand type selection (international big brands, original factory certificate products are recommended)

Auxiliary system design

1. Freezing pump matching: head (evaporator pressure loss of refrigeration unit + pipeline pressure loss + equipment heat exchanger pressure loss), flow > rated evaporator flow 10%

2, freezing water tank design: ensure the refrigeration unit efficient operation, temperature stability, according to lower than the refrigerant evaporation temperature insulation

3, freezing pipeline design and installation: to ensure the efficient and reliable operation of the unit, the design of cold loss, the pipeline needs to be in accordance with certain requirements of heat preservation, filter Settings, bypass Settings;

refrigeration host protection function; Main power switch, total power without fuse, break electrical appliance, high and low voltage switch, power under reverse phase switch, antifreeze protection, compressor overload protection, ice pump overload protection, fault indicator system, fault alarm system, ice water By-pass pressure relief circuit, anti-static spray shell, European design, beautiful and generous, the outer plate is easy to remove, easy to use and maintain.
