1、 Central air conditioning system for Villa

Small ground source heat pump unit is one of the series of central air conditioning products developed by Baoding Spring Island ground energy air conditioning Co., Ltd. the unit develops and utilizes the low-grade renewable energy which is inexhaustible but not easy to use underground (or surface). It is an integrated central air-conditioning equipment with water as cooling (heating) source medium and cold (hot) source. With the advantages of high energy efficiency, low noise, reasonable structure, simple operation, safe operation and convenient installation and maintenance, the unit is widely used in villas, residences, farmhouses, hotels, office buildings and other small and medium-sized places. The type of the system is central air-conditioning system for purification of air and comfort.


1. Advantages of central air conditioning in Villa

Home is a harbor. The air conditioning of all living rooms is realized as a whole by the central air conditioning system, which overcomes the local treatment and uneven air flow of split wall hanging and cabinet air conditioning, so that the indoor air distribution is more reasonable and the living is more comfortable.

Through ingenious design and installation, ena-sen.company makes the air conditioning and overall decoration consistent, harmonious and unified, making the residence look more beautiful and elegant.

The central air-conditioning system not only cleans the air, but also protects the indoor environment.

Home central air conditioner is equipped with fresh air device, which can keep indoor air fresh by introducing fresh air, effectively improve indoor air quality and avoid the trouble of "air conditioning disease".!

Each indoor unit can adjust the temperature and air volume at will through an independent temperature controller, and the indoor unit can be switched on and off without interference. Family members can enjoy a fresh and comfortable personal space. Considering that there are not many opportunities to use air conditioning at the same time in each space of the family, the installed capacity can be relatively reduced, and the purpose of power saving is really achieved, 30% less than that of ordinary air conditioning.

High quality and durable system is simple and reliable, and its service life is more than twice as long as that of general air conditioner.

2、 Small ground source heat pump unit for central air conditioning system of new rural construction buildings is one of the series of central air conditioning products developed by Baoding Spring Island ground energy air conditioning Co., Ltd. the unit develops and utilizes the low-grade renewable energy which is inexhaustible but not easy to use underground (or surface). It is an integrated central air-conditioning system with water as cooling (heating) source medium and cold (hot) source Equipment. With the advantages of high energy efficiency, low noise, reasonable structure, simple operation, safe operation and convenient installation and maintenance, the unit is widely used in villas, residences, farmhouses, hotels, office buildings and other small and medium-sized places. The type of the system is central air-conditioning system for purification of air and comfort. The following is a brief introduction to the single family building in the new countryside


1. Advantages of central air conditioning in New Countryside

With the development of economy and the improvement of people's living standard, heating and air conditioning of public buildings and residences has become a universal requirement. On the other hand, the national requirements for energy conservation and emission reduction are also higher and higher, water ground source heat pump central air conditioning has energy saving, comfort, environmental protection, and also has an ultra long service life, so, water ground source heat pump is the future trend.

Most of the rural areas live in separate households, and the heating mainly depends on coal stoves. The price of coal will rise sharply with the price adjustment of fossil energy every year. The heating fee will only increase but not decrease, and the pollution will be great. And the rural insulation measures are not good, the indoor temperature is only about 15 ℃. In this context, ground source heat pump system should be a good choice.

It is suitable for small water source heat pump units. For rural users with different building structures, measures should be taken according to local conditions, and various forms of indoor end can be adopted. For buildings with heating as the main part, floor heating method can be considered, with small initial investment and good heating effect. For users who need both heating and cooling, according to the requirements of building and decoration, fan coil units in traditional central air conditioning can be used, and wall mounted units and cabinet units in household air conditioners can also be used. Can be surface mounted or concealed, completely according to the needs of users.


2. Product features:

The cooling capacity of this series of single machine is from 12.4kw-96.5kw, and the heating capacity is from 14.1kw-111.7kw. The cold and heat distribution is close and uniform. The user can customize it. The selection of cold and heat is wide. The water temperature on the heat source side of this series of small ground source heat pump units is between 10 ℃ and 20 ℃, and the water temperature at the use side is between 3 ℃ and 60 ℃

The operation range of this series of units is wide: sdra-14, sdra-17, sdra-20, sdra-25, sdra-35, sdra-40, sdra-50, sdra-70, sdra-80 and sdra-95, with wide selection of high-temperature refrigerant.

The advanced technology controller (dnr-a) is a control module independently developed by our company. It adopts domestic advanced DSP data signal processing technology, which can display and control the temperature and pressure of system compressor, circulating water temperature, well water temperature, pump operation and unit electrical working conditions. It has the protection of water temperature out of limit, water cut-off of internal and external network, phase sequence, over-voltage, under voltage, over-current and contactor misoperation.

It is easy to operate, safe and reliable. Spring Island water source heat pump unit adopts the special controller of heat pump unit developed by chundao. The program programming, accessories selection and disk debugging are all subject to the company's strict process quality control procedures. The controller has the advantages of simple operation, stable and reliable operation and long service life

The water body as a low-temperature heat source is relatively stable in a year, and its fluctuation range is far less than that of the air temperature, which makes the unit operation more stable and reliable, and also ensures the efficiency and economy of the system. There are no difficult problems such as defrosting in winter and heat attenuation of air heat source pump unit.

Digital centralized control, accurate and efficient 7-inch color display screen, full Chinese color display screen, humanized design, dynamic display of operation status, with fault self diagnosis, energy self-regulation and multiple protection functions. Through RS485 / RS232 conversion interface program, remote monitoring and control function of the unit can be realized to ensure efficient and controllable start-up and stop operation of the unit; standard MODBUS slave RS232C / RS485 communication protocol has transparent application address, which can be easily connected with various universal man-machine interfaces; the standard and unified bottom system program has open logic function, and the program can be easily upgraded according to needs; peripheral electrical devices: circuit breaker, AC contactor, thermal relay, low-voltage switching power supply, air switch, sensor (PT100) and other components are domestic Know the products of various enterprises, safe and reliable, long service life.
