Monoblock Refrigeration Units

Monoblock Refrigeration Units for cold rooms — a monoblock unit is a practical and economical cooling solution that allows equipping a cold room with minimal installation complexity; it is particularly suitable when there is no possibility or desire to invest in installing a split system with an external condenser.

Operating principles of a monoblock unit

Monoblock Refrigeration Units for cold rooms — a monoblock operates on the same thermodynamic principle as any cooling system. Compressor — compresses the refrigerant, increasing its temperature and pressure; the most energy-intensive part; built into the monoblock. Condenser — releases heat into the environment; in a monoblock, the condenser is located on the outside of the housing (in the room where the monoblock is installed); therefore, the room where the monoblock is placed must have good ventilation. Evaporator — located inside the cold room; absorbs heat from the room and transfers it to the condenser; see Cold Room Panels. Installation — the monoblock is mounted through the wall or ceiling of the cold room; holes are made in the wall panels; refrigerant connections and cables are built into a single housing; installation takes 2–4 hours.

Monoblock vs split system — selection criteria

Monoblock Refrigeration Units for cold rooms — the choice between a monoblock and a split system depends on several factors. Installation simplicity — monoblock: no external condenser required; refrigerant lines are internal; installation does not involve refrigerant refilling; split: piping must be laid; a refrigeration technician is required; more complex installation. Space requirements — a monoblock releases heat into the room where it is located; the room must have sufficient ventilation; a split condenser is placed outside — heat is released outdoors; see Modular Shelving Systems. Capacity and room size — monoblocks are more suitable for small and medium-sized rooms (up to 20–30 m³); for larger rooms, a split system is more efficient and economical; BHS helps choose the right option. Cost — a monoblock system is generally cheaper in terms of purchase and installation; a split system may be more economical for large rooms in terms of operating costs.

Temperature range and application

Monoblock Refrigeration Units for cold rooms — monoblock units are available for various temperature ranges. Positive temperature (+2°C to +8°C) — suitable for storing food products and beverages; most restaurant cold rooms; widely used in the HoReCa sector. Negative temperature (-18°C to -22°C) — suitable for storing frozen products; frozen meat, frozen seafood, ice cream; ensure that panel insulation meets negative temperature requirements; see Cold Rooms. Universal use — some monoblocks can switch between positive and negative modes; a flexible solution for changing storage needs. Capacity selection — capacity must match the room volume, insulation thickness and expected frequency of door openings; BHS helps calculate.

Maintenance and operation

Monoblock Refrigeration Units for cold rooms — regular maintenance ensures stable operation and a long service life. Condenser cleaning — the condenser grille accumulates dust and grease; cleaning every 3–6 months; a dirty condenser increases energy consumption and reduces cooling capacity. Defrosting — ice buildup on the evaporator reduces cooling efficiency; automatic defrosting cycle is a standard feature; see Cold Room Panels. Temperature monitoring — a digital thermostat controls the temperature; an alarm for temperature fluctuations; HACCP documentation. Refrigerant pressure check — a specialized refrigeration technician checks once a year; refrigerant leakage is a source of economic and environmental problems.

Frequently asked questions

Can a monoblock unit be installed independently without a refrigeration technician? The refrigerant system is hermetic and does not require additional refilling; contact BHS; see Cold Rooms.

How long does a monoblock refrigeration unit last? Monoblock Refrigeration Units for cold rooms — with regular maintenance, a quality monoblock lasts 8–15 years; service life is reduced by insufficient condenser cleaning, operation at high ambient temperatures and frequent temperature fluctuations; see Modular Shelving Systems.
