What’s Chiller Replacement andHeat Pump?

HEAT PUMPCHILLER REPLACEMENT

Heat Pump’s advantages

What is Heat Pump?

Chiller Replacement’s advantages

What is Chiller?

1. More even temperatures. 2. More comfortable humidity level in the winter; not too dry. 3. Less noise and odor. 4. No pilot light or vent to worry about. 5. No seasonable change over. 6. Only one fuel bill.7. May supply hot water with excess heat generated during the

summer. 8. Fewer home fires are caused with heat pumps in

comparison to gas heating.

1. New chillers will reduce maintenance cost and increase total system reliability

2. Better control and operations3. System efficiency during operation can be monitored and

reported through chiller monitoring system4. Better control of temperature5. Ability to expand air condition system for new area by using

air-cooled split type fan coil unit

Chillers of the air condition system are the major system of electricity consumption for commercial buildings; department stores, hotel, and office buildings. Therefore, the usage of high efficiency chiller can keep power cost down together with proper maintenance

Heat pump is a system for extracting heat from source (air stream or water) and applying this heat to media such as water. We gain more comfort and saving due to less electrical consumption and nothing burn such as boiler system.

Normally heat pump working life time is more than 10 years. We can take value added and long term pay back from investment of this measure. Properly design optimizes to existing heating and cooling system can take more benefit. Replacement diesel boiler with heat pump avoids accident from hazardous fuel storage and pollution reduction.
