Compare the 16 displayed Deye solar AC, heat-pump and pump pages
Open the relevant page for source-derived content, then confirm exact model, design condition, AC/PV architecture, refrigerant or hydraulic duty, included components, files, availability and order terms.
Displayed application families
Separate cooling, heat-pump and water-pump duties
These products solve different loads and use different design inputs. A hybrid AC/DC label does not make their capacity, PV input or installation requirements interchangeable.
Wall, low-temperature and window solar AC
Confirm cooling/heating duty, climate, room load, indoor/outdoor units, AC and PV/DC input, refrigerant, piping, condensate, controls, backup/grid behavior and exact model files.
Cassette, duct, multi-split and multi-zone
Define zones, indoor-unit combination, duct/static pressure or cassette layout, diversity, piping lengths, drainage, ventilation, electrical/PV supply, controls and commissioning.
Heat pumps and water-heating routes
Monoblock, air-source water heater, swimming-pool and floor-console pages need water temperatures/flows, ambient design points, tank/loop, pumps, freeze protection, refrigerant, hydraulics and local plumbing rules.
3-inch and 4-inch solar water pumps
Pump pages require water demand, total dynamic head, borehole or source level, pipe losses, pump curve, PV/controller architecture, dry-run protection, materials and local hydraulic design.
Application selection checks
Six inputs before requesting Deye solar HVAC or pump equipment
Start with the delivered thermal or hydraulic service, then match the exact product, climate and electrical/PV architecture.
Application and design duty
State space cooling/heating, hot water, pool heating, floor console or water pumping; provide required capacity, temperatures, flow/head, schedule, occupancy/process and redundancy.
Climate and site conditions
Provide design ambient temperature/humidity, altitude, coastal/corrosive exposure, freeze risk, indoor/outdoor location, noise limits, shading and service access.
Building, hydraulic or borehole data
Provide load calculation, zones/ducts/piping/condensate for HVAC, or water demand, static/dynamic levels, head, pipe losses, borehole diameter and water quality for pumps.
AC, DC and PV architecture
Define grid/generator/backup, phase/voltage/frequency, exact modules and strings, PV/DC limits, switching priority, protection, earthing and whether batteries or controllers are in scope.
Refrigerant, water and installation scope
Confirm refrigerant and destination rules, line lengths/charge, drainage, tanks/heat exchangers, water treatment, pumps/valves, mounting, penetrations, lifting and installer qualifications.
Performance files and commercial scope
Request exact capacity/performance tables at design conditions, datasheet/manual/certificates, included units/accessories, controls, warranty, spares, quantity, delivery and commissioning scope.
Performance and application boundaries
Solar and hybrid labels do not define delivered cooling, heat or water
Final performance depends on the exact duty, ambient conditions, system design, installation, controls and available electrical/PV input.
Rated capacity needs a test condition
Cooling/heating capacity, COP/EER or water output applies at stated indoor/outdoor or water conditions. Do not transfer a nameplate value to another climate or duty point.
Hybrid AC/DC is not automatic off-grid operation
Confirm PV/DC window, AC priority, startup, clouds/low irradiance, grid or generator support, controls and whether storage is required or supported for the exact product.
Refrigerant and installation rules are local
R410A, R32, R290 or another refrigerant changes safety, charge, room/location, tools, technician and regulatory requirements. Exact model and destination rules govern.
Water pumps need hydraulic selection
Pump diameter or solar label does not define flow. Use the exact pump curve, total dynamic head, water level, pipe losses, PV/controller limits, materials and protection.

Deye solar HVAC and pump FAQ
Questions to resolve before selecting equipment from this mixed category
These answers classify the request; final thermal, hydraulic, electrical, refrigerant, plumbing and installation design remains project-specific.
Does the Deye Solar Air Conditioner category contain only air conditioners?
No. The current displayed category also includes heat-pump, water-heating, pool, floor-console and 3-inch/4-inch water-pump pages. Start with the required cooling, heating, hot-water or hydraulic duty and use the exact product family and documentation.
Can a hybrid AC/DC solar air conditioner run without the grid?
Do not assume so. Confirm the exact PV/DC input range and power, AC support and priority, startup and low-irradiance behavior, controls, protection and whether any storage or generator support is required. Operation depends on model and conditions.
How should a solar heat pump or air conditioner be sized?
Use a building/thermal load and design ambient/water conditions, required supply temperatures, zones, schedule and redundancy. Compare the exact capacity and efficiency tables at those conditions, then design electrical/PV, refrigerant, piping, drainage and controls.
What should a Deye solar HVAC or pump RFQ include?
Include the exact duty, capacity/temperature or flow/head, climate/site, building/hydraulic data, AC/DC/PV supply, refrigerant or water system, protection/controls, installation and commissioning scope, required files, quantity and destination.

Deye Solar Air Conditioners, Heat Pumps and Water-Pump Routes
Review 16 displayed pages in the Deye Solar Air Conditioner catalogue. The source category is broader than room air conditioning: it includes wall, low-temperature, cassette, duct, window, multi-split and multi-zone AC routes; monoblock, water-heater, pool and floor-console heat-pump routes; plus 3-inch and 4-inch hybrid AC/DC or DC water pumps. Select by the actual thermal or hydraulic duty, climate, electrical/PV architecture, refrigerant or water system, installation and destination requirements—not by the category label alone.
Prepare a Deye solar HVAC or pump RFQ by actual duty
Send the cooling/heating/hot-water or flow/head duty, climate/site, building or hydraulic data, AC/DC/PV architecture, refrigerant/water system, controls, installation, documents, quantity and destination.
