Application scheme of heat pump in a villa in Bulgaria for your reference

Project information:

A Bulgarian household has three rooms, one living room, one kitchen and one bathroom, with a heating area of 180 square meters.

Customer requirements:

The newly built villa pays attention to energy saving, high efficiency and stability of equipment. In response to the global environmental protection action, the owner hopes to install a comfortable and healthy floor heating system for the first floor of the villa. After some investigation, the owner chose Yuexin Heat Pump, which has a good reputation in the local area.

System review:

Yuexin heat pump unit adopts high performance DC variable frequency scroll compressor and compressor for supplementing air and increasing enthalpy.

Built-in industrial-grade control circuit can produce higher outlet water temperature and output more heating capacity. Even if the ambient temperature is as low as -7℃ and electric heating is not needed, the heat pump unit can still maintain a constant customized heat output, while the traditional heat pump can only achieve 60% customized heat output, and the heat pump can completely provide high-temperature hot water and room heating for cold areas.

It adopts DC frequency conversion technology, soft start and soft stop, constant and accurate control of target water temperature, no power grid impact, low noise, low vibration, low energy consumption, high efficiency and more comfort.

Yuexin low-temperature air-supply enthalpy-increasing DC variable-frequency heat pump unit adopts intelligent automatic heating mode, and the water supply temperature of heat pump is controlled by intelligent equation curve, which can automatically change the water supply temperature according to the change of outdoor environment temperature, and keep the room comfort unchanged while the unit runs in a more energy-saving state.

Using defrosting technology, the heating time of the unit is prolonged. By controlling the frequency of the unit, the defrosting time is shortened and the water supply temperature is restored quickly, which improves the heating efficiency of the unit and keeps the room comfortable.

The allowable operating temperature range of Yuexin low-temperature air supplement and enthalpy increase DC variable frequency heat pump unit can reach-25℃ ~ 43℃;

It runs stably at ultra-low temperature, and the heating capacity ratio is 20%~30% higher than that of ordinary heat pump.

Application effect: in December, the night temperature is -12℃, and the morning average temperature is 2~3℃. Yuexin low-temperature air-supplementing and enthalpy-increasing DC variable frequency heat pump unit is adopted, and the indoor constant temperature is 18℃. The heating cost in December is $72.4, and the electricity fee standard is $0.076/kWh, and the average heating power consumption is 30.7/day, which is very energy-saving.

Owner's evaluation: Yuexin heat pump unit is great! Very energy-saving and low noise, the running data recorded every day is a surprise, and it's not wrong!

Comprehensive comments:

The research and accumulation of design and application experience and professional technology of Yuexin heat pump products have broken through the energy-saving application of traditional heat pumps, from the wide improvement of low-temperature heating performance of low-temperature air-supplementing and enthalpy-increasing DC variable frequency heat pump to the timely and efficient control of defrosting design and the automatic change of room water supply temperature according to the change of outdoor ambient temperature. The products incorporate the energy-saving design idea in all directions, and have achieved outstanding energy-saving effect in practical application of Yuexin products.
