Efficient Air Source Heat Pump Renovation for Older Residential and Commercial Spaces

Many residential and commercial spaces that have been occupied for over ten years are facing challenges with old-style water machine central air conditioning: insufficient cooling in hot weather, resulting in stuffy and hot indoor conditions; high energy consumption over the years, leading to significant electricity bills during both heating and cooling seasons; and loud operation noise from the old outdoor units, disturbing daily rest and office work. The daunting difficulty for homeowners is that traditional whole-system replacement requires the removal of ceilings, alteration of the entire house's piping, and destruction of the original interior decoration, with a long construction period and high renovation costs. Many families and businesses have to endure the inconvenience of old equipment for a long time.

In response to this challenge, the century-old thermal energy brand, Linuo, has launched the "Air Source Heat Pump Local Renovation Special Service," which focuses on the "only replace the outdoor unit, do not change the interior decoration" renovation model. This service upgrades only the outdoor unit and the core control system, retains the original indoor fan coil and the entire house's piping, and does not require the removal of ceilings or walls. With lower costs and a shorter construction period, it can solve the three core pain points of poor cooling, high energy consumption, and loud noise in one go, providing a convenient new choice for upgrading heating and cooling in residential, commercial, and office spaces.

Targeting Old Equipment with Precision, Threefold Upgrade to Reshape the Heating and Cooling Experience

The Linuo local renovation solution perfectly fits the real usage scenarios of old water machine existing users, and optimizes the inherent defects of old equipment without changing the original indoor facilities, achieving a comprehensive improvement in the experience. For the problem of reduced cooling capacity of old water machines in high temperatures, the renovation is equipped with Linuo's inverter three-way heat pump main unit, which has an intelligent inverter temperature control system that can stably output 7-13℃ low-temperature cold water. Relying on the original indoor fan coil for circulating heat exchange, it quickly removes indoor heat and moisture during the rainy season. Even in the face of continuous extreme high temperatures above 38℃ in summer, it can stably maintain the indoor temperature at 24-26℃, completely saying goodbye to the old equipment's pain point of "the room is still stuffy after hours of operation."

For the long-term high energy consumption problem, the new heat pump main unit is equipped with an efficient heat exchange structure, which is significantly more efficient than old water machine equipment. Under the same heating and cooling requirements, it can effectively reduce the overall operation energy consumption, significantly reducing electricity costs over a long period of use, balancing comfort and energy saving.

For the noise disturbance caused by outdoor units, the heat pump outdoor units used in the renovation have been optimized with a whole-machine silent structure, and both the fan and the compressor are treated with vibration and noise reduction. The operation noise is much lower than that of traditional old main units. The outdoor units are placed in locations such as balconies and courtyards, and the indoor operation noise is almost inaudible, not disturbing residential sleep or daily office work.

Multiple Scene Landing and Real-World Testing, Proven Successful in Residential and Commercial Renovations

Currently, Linuo's heat pump local renovation service has landed a large number of real renovation cases across the country, covering a variety of scenarios such as 20-year-old old apartments, self-built villas, store exhibitions, and office buildings, with the landing effect receiving unanimous recognition from homeowners.

【Case One: Anji, Huzhou Self-built Villa Renovation

Mr. Xie, a homeowner in Anji, has lived in his self-built villa for more than ten years. The original old-style water machine outdoor unit is seriously aging, and the full-house cooling cannot be achieved even when operating at full load in summer. Local Linuo dealers went on-site for a real survey, one by one to inspect the operation status of the entire house's indoor piping and fan coil, confirming that the indoor equipment and piping can be reused normally, and only the outdoor heat source main unit needs to be replaced. The construction team only worked outdoors, without changing the indoor walls, ceilings, or furniture. The host replacement, piping connection, and overall debugging were completed in just one day, and the whole house could stabilize cooling on the day of completion, solving the long-standing problem of poor cooling.

【Case Two: Shandong Weifang Store Office Renovation

Mr. Song, the boss of a store and office area in Weifang, Shandong, with a total area of 670 square meters, was originally connected to the property management centralized water machine system of the building, and the use of heating and cooling was completely controlled by the property management. Unexpected high temperatures, cold waves, and inability to turn on during non-working hours could not meet the indoor temperature requirements. This year, Mr. Song decided to take control of the air conditioning, so he invited Linuo to go on-site for an inspection.

After on-site measurement and calculation of the cold and heat load, the project selected 3 units of 25kW heat pump main units for parallel operation, and the equipment was placed in the outdoor area on the first floor. The construction team handled a number of technical problems such as the load-bearing reinforcement of long-span pipes, outdoor piping sun protection and insulation, and long-distance cable waterproofing, and the renovation was completed without damaging the indoor decoration. After completion, it achieved independent control of heating and cooling, and could turn on the air conditioning as needed throughout the year, maintaining a comfortable indoor temperature of 25℃. Mr. Song and his team finally achieved "air conditioning freedom" and were very satisfied.

【Case Three: Tianjin Self-built Villa Ground Source Heat Pump Renovation

A self-built villa in Tianjin was originally equipped with an old ground source heat pump, which failed due to aging. The cost of repairing the whole unit was high. After the Linuo staff went on-site for an inspection, it was confirmed that the indoor fan coil and the entire house's water piping were in good condition and could be reused, and only the heat source main unit had failed. The renovation plan only disconnected the original ground source heat pump piping, and then re-matched three 25kW Linuo heat pump main units for联动 operation. The main units can start and stop according to the real-time indoor cold and heat requirements, outputting heating and cooling as needed, balancing the use effect and operation energy saving, and saving the high cost of replacing the entire house's piping and indoor units.

Full-process Supporting Services, a Stress-free Old House Heating and Cooling Renovation

Unlike traditional repairs, Linuo's heat pump local renovation is a complete and落地 service system covering the entire chain from pre-construction survey to post-construction maintenance, reducing homeowners' concerns about renovation.

During the pre-construction phase, Linuo provides free on-site survey services, where engineers conduct real-time detection of the existing water piping, fan coil, and building pipeline layout, customizing a dedicated outdoor unit matching plan based on the apartment area and usage scenarios, specifying the construction scope, and informing the timeline and cost in advance; during the construction phase, standardized operations are carried out, and outdoor pipelines are reinforced for load-bearing, insulated and protected against the sun, and waterproofed over long distances. After the renovation is completed, the original piping is flushed in a cycle to remove long-term accumulated impurities in the pipes, preventing old impurities from damaging the new heat pump main unit; after the overall debugging is completed, complete user instructions are provided, and long-term after-sales maintenance services are provided. Equipment failures and piping maintenance can be handled through official channels.
