Withair's Heating and Cooling Solutions for Greenhouses

Producing a differentiated crop while maximizing yield requires consistent and reliable growing conditions. Mother nature doesn’t always provide it, but you can. Controlling temperature, humidity, lighting, CO2 and airborne pathogens is complicated, yet Withair® gives you the authority to manage it all. We can engineer a proprietary environment that supports the genetic potential of your crop—and replicate it quickly as you grow into additional spaces.

Permanent glass house structures are often ideal to take advantage of the benefits of a heat pump heating system. The heat also enables clients the option to grow a wider variety of plants more profitably. In addition to this the "dry heat" that is produced through the ground and through the fan coil heaters can help reduce disease developing on the plants. The possibilities for ground and air source heat pumps in the agricultural industry is enormous. There are so many sectors within agriculture where this can benefit the customer, both financially and productively.

A technology-based approach to growing crops indoors

Indoor agriculture is a technology-based approach to growing crops indoors. This allows growers to specify and control the ideal environment to achieve the optimal harvest. Growers can do this by controlling temperature, humidity, carbon dioxide, lighting, irrigation, and fertilization. To maintain space temperature and humidity, systems will very likely need to be equipped with both temperature control and humidity control.

Innovate with less risk

HVAC equipment, controls, energy services and engineering expertise: Withair® has a full set of tools to help you succeed. Our holistic approach to HVAC system design innovation has been proven many times in the world’s many buildings, from data centers to hospitals, and we can apply that expertise to your facility, we’re ready to support rapid growth at your facility—and the worldwide indoor agriculture industry.

How to Solve Your Greenhouse Temperature

When comparing your alternatives, don't forget to factor in the following:

• Cost of energy
• Cost of installation
• Cost of maintenance

The possibilities for Ground and Air Source Heat Pumps in the Horticultural, Industrial Agricultural industry is enormous. Whether you are looking to heat a farmhouse, large scale greenhouse or industrial warehouse, a ground or air source heating system will help keep your running costs low and protect your business from the volatility of fossil fuel prices.
Eco-Friendly and Efficient Greenhouse Heating Ideas

More and more gardeners are looking for ways to operate their greenhouses in a most eco and cost-effective manner. Not only is there a growing desire to garden in a more sustainable fashion, but fuel costs are also rising considerably. If you need to heat your greenhouse more efficiently, use an air or ground source pump

Air and ground source heat pumps are becoming increasingly popular. Although you will need electricity to run a ground source heat pump, it will take warmth from the ground to transform it into heat that you can use in your greenhouse. An air-source pump takes heat from the outdoor air. It can either transfer it to your greenhouse air or to water in pipes to keep your greenhouse warm. An air-source heat pump is a less expensive option than a ground source heat pump. This is because no excavation is required.
Types of Greenhouse Heat Pumps

There are four types of heat pumps for environmentally-friendly greenhouse heating:

• Ground Source Heat Pumps - These draw the heat energy from the Earth to your greenhouse.

• Air Source Heat Pumps - These are the ideal pumps for greenhouse growers, providing a versatile system that efficiently heats and cools the greenhouse.

• Water Source Heat Pumps - These pumps draw heat from the water and transform it into heat for your greenhouse.

• Heating & Cooling Systems - These all-in-one pumping systems serve as an air-conditioner, a boiler, a radiator to offer underfloor heating and fan coil services.
Achieve Your Sustainability Goals

Indoor growing is inherently energy intense, but we can help reduce the impact. We offer a wide range of sustainability solutions, including Withair® equipment with high energy efficiency and refrigerants with low global warming (GWP) potential, turnkey Energy Services to help you manage both energy supply and demand, and Intelligent Services to guide continuous improvement and document results.

An Energy Assessment using Withair® Energy Optics can help you gain even greater efficiency for your commercial building. You’ll see which parts of the building are consuming more energy, when and how usage patterns differ across the enterprise. The opportunities for improvement become more obvious so you can make faster and more-informed decisions with confidence.
Monitor and Control Remotely

You need to be able to monitor and control critical growing room conditions 24/7. You need it to be as simple as a cell phone app. You need Withair’s Connected Building solutions. On-demand access to real-time information and remote system control provides peace of mind that conditions stay consistently ideal for plant productivity.
Indoor Growing

Crop growth rates, duration of growing period, plant sizes, and other variables are used to determine whether plants are kept in a single space from seed/seedling to harvest or if they’re moved from room to room. In those facilities where plants are moved, there are often several types of growing spaces with unique lighting, temperature, and humidity conditions. This allows spaces to be specifically designed for the growth phase with some crops necessitating several different spaces (e.g. clone rooms, mother rooms, vegetation rooms, flowering rooms, and drying rooms). It’s important for the HVAC designer to understand the specific conditions that must be maintained in each space, and whether the grower intends to change these for future crops.

The choice of growing space dry-bulb temperature and humidity setpoints can affect HVAC equipment sizing and energy consumption. Growing spaces with lower dry bulb temperature setpoints and drier relative humidity setpoints often require more cooling and dehumidification capacity. As a result, larger equipment must be provided, and the equipment uses more energy.
