CHRU-HTPF30 • Recuperator with thermodynamic recovery

  • Heat recovery units
  • 300 m3/h

  • PURIFICATION
    • Outdoor fresh air passes through the primary filter and F8 filter at OA side, to arrest the dust/ PM2.5/ other pollutants
  • VENTILATION AND HEAT RECOVERY
    • Introduce outdoor fresh air into the room & extract the stale air out; It recovers the heating in winter and recover cooling in summer
  • PRE-HEATING/ PRE-COOLING
    • After the first stage heat recovery, the air passes through the condensor for further heating/cooling
  • DEHUMIDIFICATION
    • The two airstreams run through the heat exchanger and condensor, it can decrease the moisture of fresh air

  • A constant supply of fresh air in the indoor spaces in which we spend more than 70% of our time is vital to our health. CHRU - HTPF 30 heat pump energy recovery ventilator is an innovative product that combines fresh air purification, heating/cooling, heat recovery, and dehumidification in one machine. It can provide you with comfortable and healthy indoor air while saving energy and money. It provides the ideal solution for air tight buildings in which the windows often remain closed due to noise, dust particles and energy loss
  • With a heat exchanger and heat pump system inside, CHRU - HTPF 30 delivers clean and fresh air in a double energy recovery system. For example, 35˚C fresh air in summer time can be cooled to 21˚C, while 5˚C fresh air in the winter time can be heated to 36˚C. It can work as air conditioner in Autumn/ Spring or at night, when outdoor is 10-28˚C. Besides, it can remove the excess humidity, prevent furniture mold build-up and keep the indoor air at comfortable temperature and humidity

Characteristics

  • Double energy recovery, COP over 6
  • Fresh air preconditioning, save your electricity bill on heating system and AC system greatly
  • Work as an independent air conditioner in suitable seasons and places
  • Low noise level of 37/42 dB(A)
  • Equipped with EC fans & DC inverter compressor to minimize energy consumption
  • Wide working ambient conditions from -15˚C ~ 50˚C
  • Indoor air quality monitoring like CO2, humidity, TVOC and PM2.5
  • Bypass - In summer, the 100% bypass contributes to improved comfort and it is controlled automatically on the basis of the measured outdoor temperatures

Working principle

Advantages

  • CROSS-COUNTERFLOW ENTHALPY HEAT EXCHANGER
    • The cross-counterflow enthalpy heat exchanger can transfer heat and moisture between the outdoor and indoor air streams without mixing them. It can recover up to 80% of the energy from the exhaust air, reducing the heating or cooling load on the compressor. It is washable and easy to maintain. It has a lifetime of up to 15 years
    • Anti-mold & Anti-bacteria
    • High Strength & Stability
    • Special Polymer Membrane
    • Washable
    • Long Service Life

  • ENHANCED COMFORT THROUGH OPTIMUM INDOOR AIR QUALITY
    • High efficiency with up to 90% heat recovery and up to 80% humidity recovery
    • No more dry air in winter
    • Pleasant reduction in humidity in summer
  • INCREASED DURABILITY OF THE BUILDING FABRIC
    • A constant humidity level prevents cracks in sensitive materials such as wood flooring and extends their lifetime
  • NO FROSTING UNDER - 30˚C
    • Because of its high permeability to water molecules, no condensation water will form on the surface of the membrane, and condensation and ice blockage will not occur under extreme conditions of - 30˚C
  • MORE COST EFFICIENCY
    • Condensate-free operation under normal conditions means there is no need for a condensate drain. This saves your customers money

Application

  • It offers air volume of 300 cubic meters per hour, which can meet the ventilation needs of 80-150 m2 residential houses, villa, hotel, office etc.
  • If you are fed up with limited space in the house by adding traditional ventilation unit, dehumidifier, air purifier, split type heat pump etc, let’s try one DC inverter fresh air heat pump system. It is available to install in the attic, basement, cabinet in the kitchen etc which take up limited space.

1. Calculation of airflow according to air exchange rate.
L= V prem.×Ach (m3/h)
where V prem. – premise volume (m3])
Ach – minimum air exchange per hour, refer air exchange table.

2. Calculation of airflow according to number of inhabitants.
L=L1×NL (m3/hour),
where L1 – rated value for air volume per one person, m3/h*person,
NL – number of inhabitants in the premises.
20-25 m3/h per one person at low physical activity
45 m3 /h per one person at light physical activity
60 m3 /h per one person at heavy physical activity

3.Choose the bigger result as the required airflow. Then choose the model with the required airflow accordingly.

  • The heat pump energy recovery ventilator should be used priority to supply fresh air then to do the air conditioning.

Accessories

  • Optional Preheater for Intelligent Defrosting
When the outdoor air is low than -15˚C in winter, it’s recommended to use the preheater. The intelligent frost protection with preheater guarantees the high efficiency at extremely low outdoor temperatures. Compared to other solutions for frost protection, it means extra savings on the energy bill

  • Optional IAQ Module
The wireless IAQ module can communicate with the touch screen control panel of HPERV with zigbee signal sensing indoor air quality and transmitting data to the control system, which will subsequently control the ERV to maintain good indoor air quality
Features:
1. Free installation, no wiring, no code matching
2. Sensing the air quality of the user's living space in real-time
3. An ERV maximum connected with 15 IAQ sensors
4. Zigbee networking, long transmission distance, more stable data
5. Micro USB 5V DC power supply, mobile phone charger can supply power
6. Linked with APP to achieve more intelligent control
  • CO2 sensor and humidity sensor (option)
