Temperature and Humidity Dual-Control Radiation Air Conditioning Five-Constant Main Unit
The variable-frequency water-source ground five-constant main unit is a heat pump unit specially designed for villas, large apartments, homestays, and clubs, offering independent temperature and humidity control for radiant air conditioning. It uses the soil as the heat/cold source and leverages four-pipe/six-pipe multi-outlet technology. Paired with a fresh air system, it provides a five-constant indoor microclimate: constant temperature, humidity, oxygen, cleanliness, and quietness. It's a fifth-generation core heating source for radiant air conditioning, different from traditional dual-supply or standard air-source five-constant units.
product key technologies
Four-control dual water temperature simultaneous output
A single unit can simultaneously output two different temperature chilled water loops, allowing the radiant terminals and fresh air dehumidification to get independent water supply. No need to switch modes back and forth, solving the common issue in traditional systems where you can't deeply dehumidify while cooling, and the temperature goes all over the place during dehumidification.
Automatic smart water temperature adjustment
The main unit links with dew point sensors throughout the house to collect indoor temperature and humidity in real time, calculate the air dew point temperature, and dynamically adjust the radiant water supply temperature automatically. This ensures the radiant panel surface temperature is always above the dew point, preventing ceiling and floor micro-pipe condensation and dripping from the source, without needing to manually change the water temperature. During the high-humidity rainy season, it automatically raises the radiant water supply temperature and increases the pressure difference on the fresh air dehumidification circuit to prioritize humidity control, completely eliminating condensation risks. This is the key protection logic of radiant air conditioning.

Floor Heating Version
Single water circuit output, compatible with floor radiation systems, comes with a dew point tracking water temperature algorithm; requires an external third-party fresh air dehumidifier unit, suitable for projects with a limited budget that only do floor temperature control and not ceiling capillary radiation, and does not support simultaneous output of two water temperatures from one unit.

Mainstream temperature and humidity dual-control model
This is an industry-patented model that can output two water temperatures simultaneously. It's the main unit for temperature and humidity dual-control radiant air conditioning. With just one main unit and one fresh air unit, you can set up a complete Five-Constant system. It works with ceiling capillary networks, wall radiant panels, and floor radiation, and is mostly used in residential and villa projects.

Top-of-the-line high-spec model with temperature control
One unit provides three separate water temperature outputs, allowing independent temperature control for ceiling radiation, floor radiation, and fresh air dehumidification. The supply temperature for the ceiling and floor can be set separately. For example, in summer, the ceiling handles most of the cooling while the floor temperature is raised to prevent cold feet; in winter, the floor is heated and the ceiling is cooler, achieving fine-tuned temperature control between ceiling and floor. This setup is ideal for high-end large apartments, clubs, or boutique hotels, though it comes with a higher cost.

Dew Point Tracking Anti-Condensation Algorithm
The main unit works with whole-house dew point sensors to collect indoor temperature and humidity in real time, calculate the air dew point temperature, and dynamically adjust the radiant water supply temperature automatically. This ensures that the surface temperature of the radiant panels is always above the dew point, preventing condensation and dripping on ceilings and floor capillary tubes without having to manually adjust the water temperature.

The four-pipe geothermal air conditioning system features dual water temperature output, with one high-temperature chilled water supply for radiant terminals and another low-temperature chilled water supply for fresh air dehumidification. It can switch freely among six modes without the risk of condensation due to its four-pipe dual water temperature output, eliminating the need for a mixing module. It automatically performs dehumidification and humidification functions
The host is merely the core component of the entire five-constant system. The success or failure of the entire project hinges on professional survey and design of the buried pipe system, insulation and airtightness of the building envelope, matching and selection of fresh air dehumidification units, standardized installation and commissioning, and the collaborative coordination of multiple processes. Only through such synergy can the full performance of the equipment be truly realized, creating a stable, comfortable, and energy-efficient indoor living environment.
