     Air-cooled water coils are an indispensable cooling system in modern buildings. As part of the central air conditioning system, the installation of air-cooled water coils involves a larger project compared to others. A significant amount of auxiliary materials and pipe fittings are required during the installation process, making the quotation list for air-cooled water coil installation relatively complex. It is crucial to be meticulous and attentive to detail. However, for those new to preparing the air-cooled water coil installation quotation list, there may be nervousness and potential omissions. Below, I share a sample quotation list for air-cooled water coil installation for your reference.

     Fan coil unit installation price - Price list - Quotation attachment itemization.The price for installing a single fan coil unit typically ranges from $500 to $1200, varying with the brand and model. The installation cost can also differ based on the location where the fan coil unit is installed. Let's take a look at which accessories are included with the installation of a single fan coil unit and their prices.

In a fan coil unit installation system, at least one thermostat, two control valves, one filter, one automatic air vent valve, one electric two-way valve, and several air outlets will be used.

The air conditioning unit includes 2 control valves, 2 automatic air vent valves, 1 electric regulating valve, 2 pressure gauges and a thermometer, 1 filter, 1 temperature controller, and 2 flexible joints.

If a cooling tower unit is in place, electric valves, drain valves, 2 supply-return control valves, a make-up valve, and a float ball valve will be required.

Air conditioning units and fan coils installation require canvas flexible connections, vibration reduction equipment, and equipment brackets.

Calculation of the air duct quantity used in the system.

The supports for the ductwork require rust prevention treatment, including sandblasting and oiling, so this cost is to be billed separately.

Fire dampers and smoke exhaust openings need to be installed on the fan coil ventilation system.

Charges for wall penetration during duct installation.

Charging for the installation of fan coil units and outdoor units.

All of these are essential items for the installation of fan coil units, so regardless of the project type, there will only be additions to this quotation list, never any reductions.

Above, we reviewed the installation accessories for fan coil units and their associated prices. Below, let's understand the basic knowledge of fan coil unit installation.

1. Indoor fan coil units must be installed horizontally.

2. Installed using a Φ10mm diameter hanger, the hanger is treated for rust prevention and securely fastened with the internal unit's fixing nut to prevent loosening.

3. The hoisting location must comply with the indoor air circulation requirements and the drawings, with a certain distance between it and the floor.

4. Installation method using a zone valve: The main pipeline between the water module and the zone valve is made of Φ40 or Φ32 PPR pipe, and aluminum-plastic pipes are used to connect the zone valve to the fan coil unit, ensuring even flow distribution and minimizing leakage. The hydrostatic test pressure is 0.6 Mpa, maintaining no leakage for 2 hours.

5. Pipelines must be insulated with a thickness of 20mm, and the condensate drainage pipeline insulation must be 10mm thick.

6. Secure with U-shaped clips or other methods, ensuring the compressive amount of the insulation material does not exceed 2 to 3 millimeters.

7. The condensate drain piping must maintain a certain slope; the slope of the drain outlet for natural drainage fan coils should not be less than 1% to ensure smooth drainage. The full water test should not leak, and the drainage test should not retain water.

8. Pipeline hanger brackets are used for secure fixation.

Installation Precautions for Fan Coil Units

1. When the ceiling height exceeds 3 meters, it is not advisable to choose the ceiling model. Because with a high ceiling, the warm air from the ceiling unit cannot reach the lower levels, affecting the heating efficiency.

2. The condensate drain pipe should be connected to the unit with a flexible hose. Failure to use a flexible hose for the connection will cause the pipe to come loose and leak, as well as cracks in the pipeline and noise issues due to the unit's vibration during operation.

3. When the room height exceeds 3 meters, it is not advisable to use ceiling blowers with diffuser outlets. Instead, use double louvre outlets with downward air outlets. Otherwise, the warm air in winter will not descend, affecting the heating effect.

4. Ensure proper indoor air circulation organization to avoid short-circuit and dead-end airflows. Short-circuit primarily refers to the improper arrangement of supply and return air outlets, where the air supply does not reach the occupied area and instead returns to the unit through the return outlet. Dead-end airflows mainly occur when the return air is not within the same air conditioning zone or the supply air fails to reach the zone. Both short-circuit and dead-end airflows significantly impact cooling and heating efficiency.

5. The fan coil units must be installed with a return air box. Without a return air box, the indoor air in the air conditioning area cannot be circulated effectively, leading to poor cooling and heating performance.

6. The air outlet, air intake, and duct dimensions and materials meet the specification requirements. Otherwise, the air outlets and ducts will be too small, inevitably leading to high wind speed or insufficient air volume, resulting in noise and poor cooling and heating performance. Generally, the air outlet size is determined based on a wind speed not exceeding 2m/s, and the air intake size is determined based on a wind speed not exceeding 1.5m/s.

7. A flexible connection, such as canvas, must be used between the duct and the air outlet. If not, the vibration during the unit's operation will be transmitted along the duct, resulting in vibration noise.

8. When using flexible air ducts, the length of the duct should not exceed 4 meters. This is because flexible air ducts are commonly used with FP-136WA to 238WA units, and they have high resistance. Moreover, these units have low static pressure. If the connecting pipe is too long, it can lead to low airflow at the farthest vent and uneven distribution of airflow among different vents.

Installation Precautions for Water System

1. When connecting the fan coil to the water pipes, stainless steel flexible connectors must be used. This prevents vibration from being transmitted to the water pipes during operation, reducing noise and issues such as pipe vibration, loosening, cracking, and leaks.

2. The installation of the flexible hose connecting the fan coil to the water pipe must be horizontal and straight, not bent. As excessive bending of the flexible hose can lead to weak spots causing cracks and leaks.

3. When connecting piping to a fan coil, a "Y" type filter should be installed on the inlet pipe. This prevents impurities and debris from the water system from damaging and clogging the heat exchanger in the fan coil.

4. When installing electric two-way valves in systems with energy-saving requirements, they must be mounted on the return pipe to ensure the normal water flow required by the fan coil unit.

Electrical System Installation Precautions

1. The equipment must be properly grounded. Lack of proper grounding can easily lead to electric shock accidents.

2. Power cable specifications must comply with the unit requirements. Non-compliance with the specifications may prevent the unit from operating properly, and could lead to cable burnout or even fire accidents.

3. Each control switch can only control one fan coil unit; it is not allowed to control multiple fan coil units simultaneously. Controlling multiple fan coil units with a single control switch can cause the motor of the fan coil unit to burn out.
