Free HVAC Plan Templates

1. Free HVAC Plan Examples & Templates

You can easily create a proper HVAC plan for a house or building using an HVAC plan template on EdrawMax. An HVAC plan is a schematic diagram that depicts the components and structure of an HVAC mechanical system. There are three key elements of every HVAC plan template, the ventilation system, the architecture of the house or building, and the devices and machinery used in the system. A proper template helps you create an HVAC plan that satisfies the environmental comfort requirements after adjusting the in-door air-condition.

The best way to create an HVAC plan is by using pre-drawn templates with the correct diagram layout and specific symbols used to represent the components of the HVAC system. You can get free HVAC plan templates on EdrawMax. There are various benefits of creating an HVAC plan using a professional template. With an efficient HVAC plan, you can provide better ventilation in your house with clean air. EdrawMax gives you four types of HVAC plan templates.

  • Standard Split System HVAC Exmaples
  • Ductless Split System HVAC Exmaples
  • Packaged System HVAC Exmaples
  • Geothermal System HVAC Exmaples
  • Basic HVAC Plan Exmaples

1.1 Standard Split System HVAC Examples

The standard split system HVAC plan includes outdoor and indoor cabinets. These HVAC systems are mainly used when there is enough space for large indoor cabinets in the house, and there is also space for a big outdoor cabinet. The outdoor cabinet holds the condenser and compressor. The air handler and evaporator go in the indoor cabinet with linked ducts. The indoor and outdoor system both connects to copper tubing. EdrawMax gives you standard split system templates with specific symbols for each component.

Example 1: Standard Split System HVAC Plan

The Standard Split HVAC system plan includes an indoor unit with a fan and coil, an outdoor compressor, and remote control. A standard split system HVAC plan uses both an indoor and outdoor unit controlled by a remote to provide high energy efficiency and superior heating and cooling comfort for a specific zone in the home. All systems are intended to keep indoor environments comfortable throughout the year. Designs can be powered by gas, electricity, or a furnace. The cooling-only split-system is ideal for residential or commercial buildings with limited square footage because it uses a condensing unit with an outdoor condenser coil and compressor. Indoors, an air handling unit comprises a cooling system and a heating system.

Example 2: Mini Split System HVAC

This Mini-split diagram depicts heating and cooling systems that allow you to control the temperature in specific rooms or spaces. Mini-split systems are two major parts: an outdoor compressor/condenser and an indoor air-handling unit(s) (evaporator). Mini-split heat pumps are excellent for whole-house or new construction applications. Still, they also make perfect retrofit additions to homes with non-ducted heating systems such as hydronic, radiant panels, and space heaters (wood, kerosene, propane). They're also good for room additions where extending or installing distribution ductwork isn't an option, as shown in the mini-split diagram.

Example 3: Heating and Cooling Split System HVAC

A heating and the cooling split system is an HVAC system that includes both indoor and outdoor units linked by copper tubing. There are many heating and cooling split systems, including a heat pump or air conditioner installed outside your home, paired with a gas furnace or a fan coil installed inside your home. Heat pumps are powered by electricity, draw heat from the outside air (even cold air), and transfer it indoors. The outdoor unit is made with a compressor and a heat exchanger, while the indoor unit contains an air handler and a fan that circulates air throughout the house.

1.2 Ductless Split System HVAC Exmaples

A ductless split system is completely different than a standard split system. It doesn't need the ducts, large cabinets, or other components for the HVAC system to work perfectly. It is also known as a mini-split system, mainly used to send warm or cool air in one or multiple rooms without a duct. The individual room units connect to one outdoor compressor. With a ductless HVAC plan template, you can determine the perfect position to install the system in your house.

Example 4: Ductless Minisplit System HVAC

Mini split-system HVAC systems (mini-splits) with no ducts have many potential applications in residential, commercial, and institutional buildings. Most are used in multifamily housing or as retrofit additions to homes with non-ducted heating systems such as hydronic. Ductless mini-split HVAC systems are also an option for room additions, and small apartments where extending or installing distribution ductwork for a central air conditioner is not feasible. Like central systems, mini-splits have two major components: an outdoor compressor/condenser and an indoor air-handling unit.

Example 5: Ductless Split System HVAC

A ductless split system HVAC system consists of one outdoor unit and one indoor unit connected by refrigerant tubing and electrical wiring in its most basic form. The indoor unit is typically wall-mounted and delivers heated or cooled air directly into the living space, eliminating the need for ductwork. This is known as a single-zone system, and it is intended to provide heating and cooling comfort to a single area. To provide comfort for an entire home, a ductless split system HVAC system combines one outdoor unit with five indoor units. Ductless HVAC systems are one of the easiest and most versatile systems to install due to the variety of indoor unit styles available. That installation only requires a hole in the wall for the wiring and refrigerant line.

Example 6: Ductless System VS Central Air

The question is Ductless system vs. central air. If you already have ductwork in your home. If you don't have any ductwork, installing a ductless system from scratch will be much less expensive. There will also be less construction mess because you need a 3-inch hole in the wall to run the cable through. Ductless systems are also best for homes with new additions that are not connected to the ductwork that runs throughout the rest of the house. On the other hand, a ductless system necessitates a vent in the ceiling or a remote unit on the wall. While the manufacturers go to great extents to make the boxes as attractive as possible, there is still something to notice. This clarifies the distinction between the Ductless system vs. central air.

1.3 Packaged System HVAC Exmaples

Packaged systems are space-effective HVAC system that comes in an all-in-one package. A packaged system houses the heating, cooling components, and everything else that is a part of the central air system of the house in an outdoor cabinet. The only components in the house are the ducts that deliver the conditioned air. Houses with no space for indoor cabinets use these systems. EdrawMax gives you packaged system templates to create a perfect HVAC plan.

Example 7: Packaged Air Conditioner HVAC

A package air conditioner is a larger model of a window air conditioner. However, unlike window air conditioners or PTAC units, it has a greater cooling or heating capacity and can typically cool an entire house or commercial building. Nominal capacities range from 3 to 15 tonnes. In this Packaged air conditioner, the conditioned air is transferred to the space to be conditioned via ducting that is typically hidden in the ceiling and walls of the building. The unit is installed outside the home, in a special room within a building, or even on top of a roof. This air conditioner is factory assembled, and skilled technicians are required to install it.

Example 8: Packaged System HVAC Plan

This HVAC package plan depicts everything involved in a central air system in a single unit located outside the home. Homes with limited indoor space for these systems or without underground spaces will use a packaged unit. The packaged HVAC system contains all of the system's components in a single metal cabinet. The evaporator coil, condenser, and compressor are all housed together to save space inside. The outdoor cabinet is connected to all of the rooms in the house via custom-made ductwork. Even though the cabinet is outside, the actual functions of a packaged central air system are controlled inside.

Example 9: Packaged System HVAC

All heating and cooling components are contained within a single unit with packaged system HVAC. These units are typically installed on the roof or the ground outside your home. They are linked to your ductwork via a single hole in an exterior wall. If you're short on indoor space or want to free up some square footage, a packaged system HVAC is good. The entire system is conveniently located outside your home. The supply and return air ducts are both connected to a packaged system. There are various types of packaged HVAC systems to choose from. The best one for you is determined by your climate and the features and needs of your home.

1.4 Geothermal System HVAC Exmaples

The geothermal system is a cost-effective and environment-friendly HVAC system that uses the geothermal energy stored under the group to provide heating and air-conditioning through ventilation. Geothermal energy is a renewable natural resource. EdrawMax gives you free geothermal HVAC system templates consisting of two key components, the ground source heat pump and the loop system.

Example 10: Geothermal System HVAC Drawing

An electrically powered heat pump cycles fluid, usually water or refrigerant, through long loops of underground pipes in a Geothermal system HVAC drawing. Heat is transferred from the building's ambient air to the ground via this process, and vice versa. As shown in the Geothermal system HVAC drawing, the three main components are the geothermal unit, the underground piping system (open or closed loop), and the ductwork. The compressor, loop-to-refrigerant heat exchanger, and controls are all housed in a single cabinet in the geothermal heat pump. The air handler, duct fan, filter, refrigerant-to-air heat exchanger, and condensate removal system for air conditioning are also included in systems that distribute heat via ducted air.

Example 11: Geothermal System HVAC

Geothermal energy system Geothermal heating, cooling, and ventilation are referred to as HVAC. To heat and cool your home, geothermal HVAC systems use energy stored in the ground. Heating, ventilation, and air conditioning can thus benefit from free and renewable geothermal energy. Although geothermal energy is commonly associated with heating, the potential for cooling should not be overlooked. Heat is then extracted from the air in your home and replaced with cool air from the ground when the cooling mode is activated. This is possible because the Earth has a constant temperature throughout the year and can act as a heat sink in the summer. You no longer have to be worried about your AC system failing, and you can reduce your reliance on mechanical HVAC.

Example 12: Geothermal System HVAC Plan

Geothermal HVAC systems can be used in both large commercial buildings and small residential homes. The only difference is the size of the ground loops that must be buried. Nydalen Business Park in Norway, for example, benefits from geothermal heating and cooling. Akershus University Hospital also generates 8 MW of cooling and 28 MW of heating. Geothermal HVAC is also used in the country's national stadium and airport. The airport investment is expected to pay for itself in under two years. Heating and cooling methods, hot water supply, and air conditioning can all be provided by a geothermal system HVAC plan for your home. The energy source is both free and renewable.

1.5 Basic HVAC Plan Exmaples

The Heating, Ventilation, and Air Conditioning systems, also referred to as HVAC, combine multiple systems in any building to move air between indoor and outdoor areas. HVAC Plan is a very important part of building construction or renovation. By including the HVAC plan in your architectural setup, you are ensuring that you have properly marked all the systems.

Example 13: HVAC Floor Plan

HVAC floor plans are drawings created by specialized engineers that include all the details required to develop, install, and maintain a building's heating and cooling system. The HVAC floor plan is critical and is created after the building's floor plans have been completed. The engineers apply their knowledge to make the most effective and efficient system possible. This system requires minimal wiring and costs while still meeting the needs of the building's occupants. HVAC plans can be used in various ways because they provide the overall floor plan for heating, cooling, and ventilation.

Example 14: HVAC System Diagram

In the following HVAC system diagram, we have a mixing box, dehumidification unit, controlled zone, cooling coil unit, heating coil unit, extract fan, damper, air handling unit, gas burner, exhaust, and more. It should be noted here that HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied by indoor air quality. According to multiple zones, locations, and distribution, HVAC systems can be classified into central and local systems. Primary HVAC equipment includes heating, ventilation, and cooling or air-conditioning equipment.

Example 15: HVAC Diagram Example

HVAC stands for heating, ventilation, and air conditioning. Such systems provide heating and cooling to residential and commercial buildings. In the day-to-day world, you can find HVAC systems anywhere from single-family homes to submarines, where they provide the means for environmental comfort. In the following HVAC diagram, we have illustrated how the HVAC works and its main components. For instance, while designing an HVAC diagram, always remember to add a Chiller/Boiler, Cooling/Heating Coil, Supply Air, Thermal Zone, and Dampers.

5. Appendix

One of the key components of an HVAC plan is ventilation. It would help if you made sure that the size of the ventilation complies with the square feet area of your house. The number of bedrooms in your house also affects the airflow. For a house between 3000 to 4000 square feet with 2 to 4 bedrooms, your ventilation should be big enough to handle 80CFM airflow. The airflow value increases with your house's size and the number of bedrooms.
