Heating System Overview

What is Heating systems ?

Heating and cooling systems have three basic elements—a source of warm air, a method of sending the heated air into your living space, and a way to control the temperature in your home.

The thermostat recognizes when the temperature is too hot, and turns the system on and off to maintain your temperature based on your preferences. A furnace, heat pump will take in existing air from inside your home, heat it, then push that air back into your living space to achieve the desired temperature.

WHAT ARE THE Type OF A HEATING SYSTEM?

- Central Heat (Furnaces)

A furnace uses fuel (gas, oil, or electricity) to create heat. The heat is transferred to your home via a heat exchanger. This heated air is then distributed throughout your home by a series of ducts. Simply put, a furnace will heat your air and then distribute it through your ducts. Heating the air.

- Boilers

A boiler uses a fuel source to heat a fluid. The fluid is then pumped through your hydronic heating system. You don’t need ductwork to install a boiler. A boiler can also be used as your home’s water heater. A boiler provides more consistent and efficient heat. Plainly put, hydronic radiant heat is the best form of heating a home. Boilers are also quieter than furnaces since there is no fan to move air through the house. With a furnace, you have to change or clean the filters. You don’t have to worry about that with boilers, so it’s less maintenance for you.

How to Control the Heating Radiators at Projects?

The TIS TRV Thermostat Radiator Valve keeps every room at the perfect temperature. It uses automation intelligence to warm rooms . This wireless, battery-powered solution offers scheduling and accurate room temperature analysis. It regulates the normal radiator by opening and closing the supply, and allows you to set radiators remotely and separately. With this solution, there are many ways to manage radiators in your house: you can automate them and schedule their operation, you can use the TIS app in your phone to set the temperature if you have internet connectivity, and you can control it manually using its on-device buttons, backlight, and LCD screen.

Floor Heating Control

Underfloor Heating Collectors Valve Functionality

In well-insulated buildings, water-based underfloor heating provides several advantages over conventional radiators when considering acceptable room temperature. Heat is distributed more evenly, cold feet are avoided and consequently the indoor temperature may be reduced by 1° or 2°C without felling cold, resulting in energy savings. Underfloor hearting will also work at lower supply temperature and low flow rates. Room temperature is controlled by thermal actuators, but with-out further system balancing, poor control may become a problem. This can be solved by installing a Pressure Independent Control Valve as zone valve control with accurate actuator from TIS and connection with each manifold controlling both flow and pressure in the zone.

The Control Valve will regulate the flow of low temperature hot water to re-quired flow by adjusting the actuator position. This helps to secure a steady temperature in the entire underfloor heating system.

Air Conditioner Cooling System Overview

What is Air Conditioner systems ?

WHAT ARE THE Type OF Air Conditionner SYSTEM?

Each type of air conditioning system has its own benefits and limitations, and the best system for a particular building or application will depend on factors such as the size and design of the building, the climate, and the desired level of control and efficiency.,There are several Tow types of air conditioning systems, including:

1- Central HAVC SYSTEM

2- Ductless Ac SYSTEM

Central HAVC SYSTEM

Packaged HVAC System :

Is Large-scale systems, This type of system combines heating, cooling, and air circulation an entire building by circulating through a network of ducts. It's often used in commercial or residential buildings.

HOW HAVC SYSTEM WORKS?

HVAC systems that use a central chiller to cool water, which is then circulated to air handling unit throughout a building to provide cooling. The air handling unit contain fans that blow air over the cooled water coils to lower the temperature of the air, and then distribute the cooled air throughout the building through ductwork. This type of air conditioning system is commonly used in larger commercial and industrial buildings, as it provides a more efficient means of cooling large spaces compared to traditional direct expansion systems. The centralization of the cooling process also provides greater control and flexibility for temperature management.

Chilled water air conditioning systems are often used in office hotel rooms as well as in other types of buildings. These systems provide a centralized and efficient means of cooling, and allow for greater control over the temperature and air quality in each room. In a hotel setting, individual thermostats in each room can be used to set and maintain the desired temperature.

The components of a central HVAC system

1 / unit indoor : This unit is responsible for circulating air throughout the building. It typically includes a fan, a heating or cooling coil, a filter, and a thermostat.

2/ Ductwork: Ducts are used to distribute conditioned air from the air handling unit to each room in the building. They can be made of metal, fiberglass, or other materials..

How TIS can control HAVC?

HAVC systems are controlled by a central control system that manages the operation of the central chiller and fan coil unit. This control system can be operated and monitored for individual rooms or areas.

The control system of a chilled water conditioning system usually includes two sections The outdoor control system and the indoor control system have the following components:

1 - air-cooled chillers with out heating system

2 - air-cooled chillers with heating system

The indoor control system

Indoor control system HVAC System Stage Cool

Indoor control system if the installation of HVAC support only Stage Cool like this example then only we need to control the fan speed and on/off for Fan Coil unit

1- control Fan speed : the control of the fan speed so we need 3 channel of relay TIS that have support function FAN, in our example we chose panel additional ADD-3R-5A.

2- panel TIS ( Luna ,IO-AC-4G ): like Thermostats located in each room, these panel measure the temperature and send signals to the control system to adjust the cooling as needed.

indoor control system HVAC System Stage Cool and Stage Heat

Indoor control system if the installation of HVAC support Stage Cool and Stage Heat like this example then we need to control the fan speed and mode of HVAC like cool and heat and Aux

1- HVAC MODUL TIS : This module has 6 relays to control multiple fan speeds (low, medium, high), cooling, heating, and auxiliary contact. Keep in mind that the auxiliary contact can be configured for both a dehumidifier and/or heating/cooling pump.

2- panel TIS ( Luna ,IO-AC-4G ): like Thermostats located in each room, these panel measure the temperature and send signals to the control system to adjust the cooling as needed.

Outdoor Chiller Controller system

outdoor control system is Chiller Controller: responsible for managing the operation of the central chiller, including the control of the refrigerant flow, compressor speed, and condenser water flow. and this controller can be integrated with TIS Protocol via Modbus.

0-10V / Variable Valve (VAV )

Variable Air Volume. VAV stands for variable air volume. this systems are very common in offices. This is because they are much more energy efficient compared to the CAV model (Constant Air Volume).

VAV allows zoning within the building. That’s ideal for most situations because every room in a building will experience a slightly different heating/cooling load. VAV systems allow each room to control the amount of cooling, and possibly heating, individually. Each room is supplied by the same main AHU and ducts. Different parts of the building may have dedicated AHU’s and ducts, for example the south and north sides of a building or selected floors depending on functionality.

how we can control VAV ?

Type 1

Relay Based Valve

Control Relay Based Valve using TIS

Controls VAV from 0 to 100% with Open and Close the damper using TIS Relay Channel

Use ADD-3R-5A

Controls VAV from 0 to 100% with Open and Close the damper using TIS Relay Channel

Use VLC-12CH-10A

Type 2

Control 0 - 10V VAV

Ductless Mini-Split AC (VRF)

Ductless mini-split air conditioning (AC) systems are a type of HVAC system that provides heating and cooling without the use of ductwork. Instead, they use individual air handling unit (indoor unit) that are mounted on the walls or ceilings of each room, connected to a single outdoor unit (compressor) through a small conduit. These systems can be used to add cooling or heating to specific rooms or areas, rather than to the entire building. Each indoor unit is equipped with its own temperature control, so each room can have its own desired temperature. The outdoor unit is typically installed outside the building and is connected to the indoor unit through the conduit.

How we can control VRF with TIS?

FUNCTIONS

TIS VRF Controller is the central controller that can manage up to 32 Indoor unit in one space individually or as combined. TIS-VRF–AC can monitor or control the AC unit installed in each room of the building from the places such as the management office of a building or the administration office of a school.

SPECIFICATION

Ductless Ac SYSTEM

How can TIS control Ductless Ac system? As it is support infrared control , control using TIS IR emitters devices?

3 option of device TIS to control AC the From IR that you can use:

IR Learner

TIS Control company’s products are designed to support all types of homes’ smart needs. In order to make this happen, we’re introducing the IR Learner—an intelligent code learner that enables the TIS network to be configurable with any brand. If an infrared AC Brand doesn’t work with TIS’s IR solutions, such as the Energy Servant 10F Sensor and the IR Emitter, it’s because its code is not available in TIS’s smart library. This is where the IR Learner saves the day. It learns the new code and records it in its intelligent memory. You can transfer the new data to your PC through the USB port and then upload it to TIS solutions with infrared capability. Remember, keeping a code library in your PC is a valuable backup for future projects.

You can also test the new code’s accuracy before any information is added to the database. The IR transmitter option in this device makes any new data testable.

TIS’s engineers are proud to enrich your smart lives wherever you are and whatever digital brand you use.
